Hi I cannot get rid of play in my wheel bearings.I replaced the bearings, changed the stubb axle and trailing arm all to no avail.The bearings I used are ruville which are supposed to be the oe manufacturer.The castle nut was torqued to 300lbs/ft.Could i be doing something wrong? Hope sombody can give me some help
Thanks Peter

Some amount of play is not uncommon and it's due to parts other than the bearings. If it's excessive, you can look into replacing those parts - it's been gone over several times before, so a search should bring up more specific info.

Peter did you remember to replace the spacer between the inside bearings, and the outside bearings? Also check the wheel nut for bad threads, the spindle for bad threads or worn splines, and also the rear drums (if you have them) for worn splines. If you've replaced the bearings the excess play is probably coming from something else. How is your cv-joint? How old are your rear drums?

The spacer should not need to be replaced unless it is in fact crushed or has spun against the bearing races. (I just had one fail in fact)

Higher torque on the nut will do absolutely nothing to lessen the play. All you will do is crush the spacer and then you WILL need to replace it. Stick with the specs. (The 924/944 chassis cars that call for higher torque have a completely different setup on the rear stub axle. This is all the alloy trailing arms. You are talking steel correct?)

The axle may eventually stretch. Trash it.

I have yet to see a 924 rear axle that had no play.

This has been discussed ad nauseum.

The play everyone 'feels' is the radial play. The rear radial play is effectively controlled by the fit of the outter bearing in the arm and around the axle. It is what it is. Parts tolerance stackup.

Axial play is effectively controlled by the fit of the inner bearing against the 'C' retaining ring. There is a spec for this - it requires you have different thickness rings - almost no one checks this - you have to really work hard to feel it. I always set it and it has no perceptable affect on the play felt at the wheel.
