Dear all I am new here and hope you can help me with your experience.

I own a 2006 Jaguar XKR (first X100 series) in excellent condition, with 100,000 km.

The car has two problems for which we are unable to find a solution (everyone has their say):

Play
The rear wheels have axial play at 12 - 6 o'clock. Is this normal in your opinion?

Some say it's the bearings, some say you can put shims on them to adjust them, others say they're not adjustable and shouldn't be touched to prevent them from seizing.

Do you have experience with this?

Do you think the play could be due to something else?

There is no noise typical of a broken bearing



Noise
Also on the rear axle you can hear dull, constant knocking noises on the ground speech.

Do you have experience with this?

We did a test and the shock absorbers are OK.

Could it be the upper rubber end plates of the springs? The handbrake cable banging?


I hope you can help me

 

I know a little play is acceptable, or at least that is what i've read. Wish I knew more.

There should be 'some' play at the differential output stub axle. The bearing has a load from the axle being used as the 'upper-control-arm'.

The upper rear damper mounts and spring isolators are known to disintegrate and cause a 'metal-on-metal' noise.
The brake shoe assy can make noise on 'bumps' if the cable is too slack.(take the slack out of the handbrake cable)

 

I would say test both L and R. If play is similar then normal. The L rear bearing typically goes out first an indicator is you will have abs warnings. If it is bad that also will give a knocking, roaring noise. The bearings are not 'shimmable'...replace if bad.
