- What's wrong with my XT hub?
I was investigating a squealing rear brake at the weekend – the brake seems fine but there’s lateral play in the wheel which is causing the brake to drag.
The axel appears solidly held by the QR but there’s quite a lot of movement between the hub and axel. Not enough for the wheel to foul on the chainstays, but still an alarming amount of movement.
I’ve never dismantled a hub, so:
– what’s the likely problem? Is there something which could just need tightening up, or am I more likely looking at replacement of the loose hub bearings. Or could the whole axel be worn?
– how straightforward is it to replace the bearings? Looks easy enough on Youtube, but in reality….?

easiest with the proper tool and they’re really cheap as they’re stamped out of sheet steel on the cheap ones.
I’d assume that you’ll need to dismantle and regrease everything before you reassemble and sort the tightness on the bearings out.
Have a look at the park tool site for details on how to do this.Posted 4 years agorascalMember

Cups of my rear XT hub were knackered – after a lot of pondering my options, which included stripping out the old cups and using a donor hub to replace them, I bought a Hope hub on a DT Swiss rim! Got that nice clicketty-click noise which annoys other people now too 😉Trent SteelMember
Saying the hub is knackered buy Hope is not very helpful since no one could possibly know if it was damaged from that description……
Its could be as little as the cones needs tightening cos they have come loose, which is 2 minutes job, may want to locktite it too.
if you don’t have cone spanners, adjustable ones will most likely work
However it may be a good idea to take a peek inside to check bearings, grease etc are ok before just tightening them up
Loads of stuff on Park tool website and look at the hub specs on the Shimano website so you know how many bearings each side takes (just in case you drop one and don’t notice when re-assembling)
Its not Hard just make sure you lay the pieces out in order so that you don’t get confused when putting back together
Good luckPosted 4 years ago
Thanks for the help guys.
Think I will invest in a couple of cheap cone spanners (I won’t use them often enough to justiy expensive ones) and have a go at replacing the bearing and tightening up the cones.
Are bearings just bearings, or do I need to look for a certain type/spec?
Anyone know how many there are in an XT hub?

“if you don’t have cone spanners, adjustable ones will most likely work”
for about 37 seconds – they will come loose again if you use an adjustable as the cones will not be locked in place
Multi fit cone spanners and a rear axel are one of the staples i keep in my touring kit when im loaded touring on shimano hubs.
you can do the job with 2 cone spanners but without cone spanners anything you do is temporary.Posted 4 years agocookeaaSubscriber
TBH I’m coming back round to the idea of using Shimano Hubs, Nothing against Hope or the like, I don’t think they are mechanically unreliable as some seem to find (YMMV), but an XT “Donor for the OPs would be ~£30 (You could probably go cheaper and cannibalize a Deore I think for ~£20) and for that you’ll get a new axle, Bearings/cones, QR and Freehub…
Vs all these suggestions of buying a new Pro2 and building a new wheel… ~£140 plus the cost of spokes/rims and time to build (or getting a shop to, or just buying an off the shelf “Hope Hoop”)… and even then you are still going to need to do some maintenance/bearing replacements down the line… what have you really saved?
IMO for the cost of a pair of spanners, a “Donor Hub” and a bit of time learning a (not all that tricky) skill you’d be saving upwards of £100, and have the wheel back in a functional state much quicker…

Madpierre – thanks, thats probably the clearest guide I’ve seen
APF – very generous offer mate, but I’m in Hertfordshire. Thanks anyway

I’m more averse to taking stuff apart, buggering it up more that it was already, then taking a box of bits to the LBS and confessing my incompetence!Posted 4 years ago
Agree with your point though – I’d rather learn how to do it as it seems like one of those things I’m likely to do more than onceduckersMember
Had a similar issue wih XT wheelset a few years back, stripped for investigation and found the inner hub shell cracked, so returned under warranty. Strip it and have a look, its not too difficult but unless you already own, or can borrow the correct tools (casette tool, cone spanners, wrench, etc) it can quickly turn into an expensive job, although you should probably own that kit anyway and carry in your trail bag, so its a good investment.Posted 4 years ago
