I have just finished build a mega am and if you grab the rear wheel and give it a pull there is a loud creak from the rear end. One of my riding buddies has just bought a brand new mega tr and has the same problem. Has anyone came accross this before abd know of a fix?
Cheers

Have you both tried it without the wheel?
Could be the wheels maybe?
Checked all the bolts are done up properly? They sometimes may not be from the factory..
Hmm not quite the same but my TR frame has a clicking / creak coming from
the rear end. Have looked at / eliminated all the usual suspects.
Seems to be under load as somethings loose or too tight dry???
Grease and torque all the bolts to the specified torque?
Check the maxle is done up tight?
Make sure it's not coming from the wheel (spokes or bearings)?
Undo the shock and cycle the bike to make sure everything is smooth?
I've just finished building mine and it doesn't make any noise at all, but that doesn't really help you out.
Yep, same thing with my mega. Narrowed it down to the seat stay pivot bolts being lose and needing grease. The knocking went but has now returned I think due to a cracked bolt which I've bunged a break mount bolt in for now.

Check for play in the rear chainstay pivots, I know three people who have bought 2013 megas and all had play in the bearings/pivot points, all became obvious after the first ride on them.
They all got fixed under warranty, something to do with needing spacers in the pivot points. It's a known issue and is easily sorted.
Thanks for the replys guys, il wing an email of to nukeproof and see what they say about the chainstay pivots
Mine creaked on the main pivot bearings. There are spacers between the bearings and the frame that do not fill the space as they are smaller than the bearibg and I am sure mud gets in. Anyway I cleaned and greased then and the creak went.
Has anyone had any luck getting hold of nukeproof to resolve this creaking issue? I've emailed and facebooked nukeproof and emailed crc but no response.
MY 2013 TR creaks too. Happens when i plonk down on the saddle, compressing the suspension quickly. Need to grease and see if that helps, but not tried it yet.
I thought I had the same problem on my Mega a/m but then realised it was my aching bones. More oily fish I reckon 😕
Possibly cured mine with a strip and re-pack with grease of the pedals. We will see on the next proper ride.
If not next will be a chase out on the non d/s BB thread, as the BB is tight when fitting.
Ive emailed nukeproof 3 times and had no response, anyone have a number for them
go through your dealer/shop - they will go straight to hotlines.
Everyone one that's been out here (BC) has creaked like a barn door and needed constant pivot maintenance.
I think I have the same issue, not sure where the knock is coming from as it reverberates through the frame.Has anyone more info on the solution to this. I've replaced the chainstay bushings, shock mounts. Not had the bearings out yet. Would like to know if anyone has a fix as this is doing my head in.
Cheers.
Hi any news on this? I can feel movement when pushing on the pedal and holding the pivot above bb with my hand. It also makes a sound everytime. I will contact crc Monday and ask about these spacers that are mentioned.
Update here pedal re-build / grease did not cure.
Next is a BB chase as the non D/S thread is very tight when fitting the cup.
UPDATE . Got a reply from nuke proof apparently its a common issue and there is an upgrade part kit available CRC are sending me the kit free of charge and if i am unable to fit it myself they will reimburse me for LBS labour charges.
Which kit on CRC is it rab5474 ?
Never had an issue with this on my older 2010 model. 😐
I dont think its sold as a spare part but it is supplied for free if you get in touch with with your retailer, my riding buddy whent through his lbs where he bought his bike and they are supplying him with the upgrade kit as well
This is the reply i recieved from nukeproof
Hi Robert,
This should be a really easy thing to get fixed. Please contact the dealer that you purchased the frame from and ask them to have a look at the pivot for you. I would strongly advise your friend to do the same. There is a potential issue with slightly mis-sized hardware in the pivot and your dealer will be able to tell if this is the case and remedy the situation for you.
Best regards,
Sam
When i phoned CRC they said it was quite a common issue with the 2013 frames and had the upgrade kit posted to me straight away, but havent recieved it yet so cant say what exact parts need upgrading
Thanks
Thanks for the update. I'm going to contact them on Monday.
Ah, that makes sense. I had my 2013 TR in pieces today, to grease the pivots and try to sort the creaking. In the pivot just above the BB there are 2 thick (plastic i think?) washers either side of the frame/seattube. They sit between the frame and bearings set in the end of the chain stay, in a recess. I thought it was odd they're above half the size of the recess they sit in.
Guess they'll just send out the correct size washers. Easy job to fit. Hope that sorts it, the creaking/cracking noise is getting louder on mine each ride.
Just hope CRC can sort the issue with my very noisy shock too!
Awesome guys, thanks for finding out what the issue is. I bought my frame second hand and need to know what parts to ask hotlines or crc for. Once you know what parts are required please post them up. Cheers.
Gonna save this thread 'just in case' but i have had no issues with my 2013 mega am *fingers crossed* 😉
UPDATE received the parts today and it is the bush kit as linked a couple of posts above, i will update again once i have fitted the kit with results.
Rab5474, let us know how you get on once they are fitted. I have already replaced these just after I had replaced the shock bushes as I thought they were the most obvious source of the knock noise. I've been in contact with CRC and they confirmed that the noise is likely related to worn chainstay bushes and have refunded me a set as I have recently purchased them. Hopefully that is the cause!
I just tightened my rear pivot up and it stopped creaking. IIRC I went over the recommended torque spec but its been fine ever since, so, meh.
Ah, lucky I read this, just about to upgrade to a TR! CRC are on my doorstep so I should be able to get sorted quickly if a problem comes up.

Ignore that. CRC have told me NP don't recognise any issues with the pivot just above the BB. They have sent me the bush kit linked above. Fitted it today (it's for the pivots at the back, near the dropouts, where the seat stays meet the chain stays) and was pretty straightforward. Looked pretty much identical to the stuff i took out. [i]Maybe[/i] the thickness on the top hats were a little big different?? Can't be sure.
I have now greased every pivot too. Back out on it tomorrow. Fingers crossed. Effin fantastic bike. Just wish it would quieten down!
Any updates? I just ordered a Mega TR myself so would very much like to hear about this issue being easily sorted out. 🙂
Did 20 miles round Surrey Hills since replacing the bushes at the back with the ones CRC sent me. No creaks. Yet. But i have also now greased every pivot in the process of chasing the creak. Hopefully it's sorted but lets wait and see.
@svalgis. You'l love it. I replaced a Santa Cruz with my TR and it's 10x better. Best bike i've owned. Mine did not creak out of the box. Took at least 100 miles to develop the worst creak.
Ok, so not sure if this is a new sound but my 2013 mega tr frame makes loud cracking sounds from the BB pivot but only when its tightened to factory spec. When the pivot bolts are loosened the bike runs smooth. Any Ideas ?
Might be worth noting that there is no drain hole in the bb shell, so water can collect and then the bb creaks and eventually creaks. I drilled a 3mm hole near the isgc tabs.
The main pivot bearings lasted through winter and the others could do with replacing, will consider running a marshguard to reduce the amount of mud collecting at the main pivot bearings.
I've now replaced pivot bearings, shock bushes, rear chainstay bushings and even the bottom bracket yet the knocking noise still remains. All bolts to correct torque settings. Only thing I can think it could be now is the shock. New shock on order, fingers crossed that fixes the noise. What else could it be?
I've recieved and built up the frame now and I have a slight but definitely noticable play somewhere in the rear triangle, most apparent if I grap the wheel or seatstay and wiggle them by hand. I also get some very slight creaking while riding which I guess (hope) is related. Do others with the creaking also experience this play, or is it a whole other issue?
All linkage bolts are tight. I've emailed CRC to see what they have to say about it but would love some input in the meantime.
Most importantly; do you reckon it's safe to ride it in the meantime?
The upgraded parts kit that crc sent me stopped all proplems of creaking / play, i also popped all bearing seals and gace them some fresh grease at the same time
Good to hear. I realised that I had missed the chainstay/seatstay bolts, which were just a little bit loose - when I did them up, the play temporarily disappeared (but came back again during a ride). I guess that will keep it in check until I get the replacement parts.
Fantastic frame otherwise. 🙂
Mine arrived last week not got round to fitting em yet - do I need a press or owt?
No need for a press mate tho they can be a bit of a pain
Are the chainstay/seatstay pivots assembled dry? It's just a metal and poly bush so I don't think anything is required. Mine developed play there, replacement parts are fitted and problem gone for just now.
The chainstay/seat stay need to be installed dry without grease. I was informed by hotlines the grease will eat away at the polymer layer to the bushings. As folks are saying that tightening the bolts to the correct torque setting is stopping the movement/noise I'm thinking my torque wrench is wrong.
Noticed that my TR has the creaking on last nights ride, just around 2 weeks in of ownership. Will contact CRC and get this upgrade kit.
I've got an annoying creak around the bb on my new mega am frame too. Did people get it when pedalling/putting power down? I've stripped and greased pedals and bb, will replace the bb this week too. If that and checking the pivots doesn't solve it, I'll get in touch with crc.
Also, a slightly different issue - how loud is the monarch plus shock on everyone's frame? Mine seems to make a lot of noise on compression (sounds like air/fluid pushing through at high speed). It seems to work ok but I'm sure it clonks slightly on rebound too.
My AM doesn't creak and the shock is pretty much silent. Not sure if this helps! It's done about 500km since late feb and I've checked the torque a few times on all the pivots, but no issues. I do have a whole spare set of bearings/axles/hardware etc for the alps but decided against pulling it apart because I didn't want to introduce issues that aren't there today.
See if it creaks after a week being thrown down big mountains. Probably less than me 😉
I've had the crack/knock noise on mine and it was the shock bushing. Changed em and not a peep since.
CRC are sending me the bushing kit this week. I'll report back on my findings! It's a bloody good bike this...
Probably a daft question as everyone else seem to have figured it out, but how do you remove the old bushings and install the new ones?
I used a small socket to drive the metal bushing out then a drift to knock the plastic sections out.
Thanks. I ended up using sockets and that worked out okay. The creaking persisted though, which I finally managed to cure just the other day by greasing up the rear maxle (which I had used completely dry up to then). So I probably never had a problem with the bushings to begin with... Oh well, all quiet now!
Update on my creaking. All quiet since greasing up my rear maxle!
Also, the suspension 'clunk' I had which I thought might be pivots or the shock turned out to be a sticking SRAM clutch mech.
Has anyone still got this creaking noise or any updates on how you got rid of it.
Cheers
Anyone, your input would be appreciated.
Well, what's your situation? Have you tried new bushings and greasing the rear maxle? For a while I also experienced more of a squeeky sound, after getting rid of the creaking, which was fixed by greasing the suspension pivot bolts (they were all installed dry which seemed a little odd to me).
My knocking has returned 🙁 any one else had it return?
Warranty bushes sorted mine, thought it had returned but was a cracked freewheel. Frame has been silent ever since bushes
I've replaced bushings, bearings, shock mounts and correctly torqued up the bolts. I'm suspecting its the monarch that's at fault waiting on a ccdb inline to turn up to prove me correct! Just interested to hear if anyone has found a definite fix for this. Not tried greasing up the maxle but mine always has some chain lub on it. Does everyone who has the creak/knock have a clutch mech? Could that be the potential cause, this is my first clutch mech. Cheers.
Update. Mine is now fixed. Shock was the issue. Replaced with ccdb air. Vast improvement over the monarch.
Mine has movement in the rear triangle has returned again, tried everything, different shock as well. Now onto crc for replacrment / refund
Have you upgraded the bearings. The nukeproof ones are supposed to be shite. Hopefully you get a fix for yours and mine doesn't develop that noise again.
I got the chainstay pivot upgrade kit, that cured it for a while, what bearings need upgrading, i'm assuming all pivots?
The main bearing set, I've had mine all replaced but with nukeproof ones. Some folks recommend others as the nukeproof ones are not particularly good quality. My main pivot ones were seized causing some notchiness in the travel. Also had the chainstay pivot bushings replaced as these are seen as the weakest pair on the frame.
This is ominous, I have just bought a mega tr frame. I wonder if CRC have sorted them out or if I should just send it back before things get ugly..
So, figured out my creaking and cracking sounds by replacing the bearings with enduro bearings and things are allot smoother. Wouldn't go with nukeproof bearings again as they all ceased up pretty quickly, say 7-8 months.
I've got major play in my rear triangle. Going to strip it down tonight and also fit the replacement bushing kit I never got around to fitting. I have noticed that the rear shock moves side to side on the bottom bushing by 1-2mm. Not impressed with the build quality.
Reviving this thread, as I'm replacing the chainstay assembly on my TR. Can anyone advise how you remove / replace the pivot pin / bearings?
I was stuck with that too. Could not for the life of me work out how to get it out.
Easy, now that I've done it likely about five times now. Flip bike upside down, rear wheel off, loosen the screw, chap the the screw lightly to loosen the bolt and remove. Once out you can pull the frame apart and clean. Reassembling is a wee bit tricky you just need to realign it correctly to get the new chainstay pivot bolts in. Both sides can be done in 5 mins.
As there's a screw on both sides, does it matter which side / screw you tap from, or will the pin come out in either direction?
Mine has creaked like a bastard from day one. Awaiting response from CRC.
I've just received my bush kit from CRC, does anyone have a drawing that shows where they go? Thanks
Ignore my last question, I've just found [url= http://www.ebay.com/itm/Nukeproof-Mega-AM-TR-Bush-Kit-4x-Bushes-2x-Bush-Sleeves-/181674498723 ]THIS[/url] which seems to answer it nicely!
Hmm, my Mega TR creaks slightly when seated only. That what others are experiencing or when stood too? First FS for me so just assumed nievely maybe that it was just part of everything moving :-/
Grease time then.
I got my local shop to ring hotlines, and they denyed any knowledge of this or an upgrade kit. I ended up greasing the seat stay pivots and all has been fine since.

Can you just remove covers for that or do you need to strip them?
