Had bearing replaced on one side on a 240 mtb hub about 2 months ago but there’s sideways movement,could it be the axle and skewer worn? Wheel 2 years old and would 135 axle be the same as 142? Not sure if the difference is made up with the adaptors.

The axle’s definitely the same so it won’t be that. Play can be a lot of things, you need to get it in bits really. It’s not very likely to be axle wear, more likely to be an issue with a bearing- either wear or fitment. TBH I’d suspect that new bearing first of all.

The 240 has a rep for being hard to work on but it’s not really, it has one bearing which needs special tools to get at but the other 4 are all just like any other cartridge hub, so you can strip and rebuild it pretty easily. And the one hard-to-access bearing is very well protected so lasts for ages in normal use.

Depends, in my experience this is usually caused by people buying Non-DT bearings which aren’t within tolerance and/or bashing them in wonky with a hammer & a socket set and flaring the hub shell.

There was also an American ebay seller offering ‘DT compatible’ axles a while back, these were a tiny bit too small and tended to also generate play as a result.

So long as you’ve used all DT parts and fitted them using the proper tools then you shouldn’t have any play.

Can’t really say any more without having a look at the hub, maybe talk it back to the shop or give TF tuned (the U.K. service center) a call.

TBH if you’re going to fit things wrongly, you can do that with the proper tool just as easily as you can with a good alternative, ie correct sized sockets in this case. It’s the operator that’s the issue in both scenarios.

It’s just an industry standard bearing so any known brand- FAG, INA, Koyo etc- from a reliable source should be absolutely fine. But cheapies will often cause problems. Hopefully the shop’s used decent ones.

I would expect that the DS hub bearing is not fully seated. This is the trickier one to do right, and would give you a smidge of L/R play but look mainly ok. Does the freehub seem to sit slightly proud of the body?
