Slack feeling in rear hub

Recommended Posts

Hi,

I started stripping down the rear end with a view to fixing the rear hubs. I noticed after removing the discs on the right hand side that there is quite a lot of rotational play in the wheel hub before it engages the diff and starts to feel resistance. I would say about 5-10mm of movement at the hub. At the end of travel there is a metallic clunk noise when it engages the diff. There is no play laterally and the bearings seems smooth, I am wondering if the noise I hear could come from wearing driveshafts?

It may be that this much play is normal, but I can't feel it on the other side (so far no stripped, so brake disk and wheel weight could be making it harder to detect.

Any help would be great :)

This will be your CV joints that have worn. I had exactly the same noise and removed both driveshafts. When I clamped the driveshaft in a vice I could rotate the CVs a few mill each way which seems minimal but when the driveshaft is installed in the car looks like a huge amount of play. My inner CVs were terrible so replaced them and it was miles better. Remember you cannot replace just the outer CV joints on these, just the inners.

See my thread here.......

Thanks for the quick response. It definitely feels like the inner CV joint has worn pretty badly. I will replace them both, are the GKN kits from Design911 reasonable quality? The good news is this looks like much less of a ballache than replacing the wheel bearings!

The bad news is that my alignment bolts have all seized, so I have a few fun hours with a hacksaw to look forward to :D

Do you still have the CP4L product number for these? I can't find them on their website.

Cheers,

Brilliant, got those ordered with next day delivery :)

Nicely done :)

They're easy to swap however you need to remove the exhaust or part of it to get the driveshaft out though you may have worked that out already!
