Stuck in Majorca, and my rear hub has developed what appears to be know on the web as the mavic death squeal..basically freewheeling at speed It starts making a horrendous grinding sound which goes away as soon as I turn the pedals.
Obviously I'll need to get the cassette off, but once this is done is it simply a case of packing with grease as a short term fix. Or is it going to require some replacement parts?
In Majorca at the moment, last day tomorrow and going for a big ride with alot of descending, so will need to buy a chain whip and big spanner or ask a bike shop to do it, as don't fancy riding it as is. But I can't be assed taking it apart only to find it's not going to be an easy fix with a bit of cleaning and grease.
Also, I'm in alcudia, can anyone recommend a bike shop that sells tools?

No idea what Mavic hub you have but I've had a couple of Mavic wheels that have done the same thing you're describing.
Both of them were just a dry whiteish coloured bush in the freehub that needed a bit of grease on it.
If I remember rightly (I don't use Mavic hubs anymore now...) You need to use a really really light oil on a bushing or something in the hub. Sorry to not be more help, it's been a while! Just be careful if you do put grease anywhere and from past experience I think chain lube was too viscous.
It's a 2015 ksyrium elite. Daft question but can I remove the free hub body with the cassette in place as I don't have a chain whip with me.
Also, how do you remove the non drive side bearing cover. I read that I just stick a 5 mm allen key in both sides and turn in opposite directions ..a 5 mm fits in the drive side but not the non drive side. I assume I have to remove the cover bit it won't pop out.
Been here before . Oil is short term but reality is that Mavic make poor hub internals and use a plastic bush - aluminium interface instead of a bearing.
Your plastic bush has worn the freehub is moving and it howls.
Oil/grease takes up the play for a while -or a short period depending on how lucky you are.
Might be worth asking a shop if you can hire a wheel for a day rather than ****ing around and still ending up stranded..
Or not.
But it depends how lucky you feel.
Wife's cross max went from death squeel to not freewheeling pdq.
My ksyrium have been grand for many years.
Won't rush to buy more Mavic wheels.
The non drive side has a push fit axle end. Pull that off and inside will be a 10mm allen key socket. Use the 5mm allen key on the other end of the axle and undo and remove the axle assembly. The freehub should then pull off (with cassette on), carefully as there are pawls and springs that can easily ping off. Also there will be a spacer in the freehub that needs to locate on the axle inside the freehub when you reassemble it.Clean out the freehub and put some wet lube chain oil in it, or similar light oil. Put hub back on, screw axle together and pop the push fit end back in.
Edit: that push fit axle end can be difficult to remove by hand, sometimes I have to use mole grips or the like.
Yep, I can't manage to remove the push fit axle ends. Will try to find a diy store tomorrow morning. Useful to know the cassette doesnt need to come off.
There's only a rubber 'o' ring holding it in place but it can hold fast!
I only have dry lube with me..Will that do as a fix for day or similarly wd40 from a hardware store?
plain old 3in1 would be better than dry lube. The dry lube will be a bit too grippy on the freehub bush when it dries. WD40 should be ok for a day or two I think. Load the freehub up with a nice pool of oil.
I'd really not put any WD40 on it.
As above, I’d avoid WD40 and go for 3 in 1, or similar light oil. If you get really desperate, a light olive oil might be better than nothing.
I think you've got the answers but you just need to open it up an oil it. Mine was fine for ages after this. I probably use a wet lube or of about that consistency (engine oil?) I'd see what the diy shop has.
Got any mineral oil brake fluid? That’s what Mavic recommended for my road wheels.
As above, I've used mineral brake fluid in Mavic hubs a few times.
I suspect WD40 or dry lube won't do much. IN your shoes I'd probably be looking for a wheel to borrow from someone.
A clean and a few drops of 3-in-1 quickly sorted my Crossmax many hundreds of miles ago. I saw recommendations for light oil such as sewing machine oil, but went for what I had handy.
Kits to replace the white bush with bearings can be had from eBay....
From memory the hub internals should be lubed with mineral oil.
I had a crossmax which developed the squeal. Replaces the plastic bush with a ceramic bearing using a kit off eBay. It has been ok since.
