2001 xk8 One of my rear hubs had bearing issues two years ago. I marked it down as my right rear in my notes. I had the work done at local well known shop.

So last week I had this feeling my rear end wanted to hula on some ribbed roads. I lifted car and found left rear wheel could wobble some. I checked the lug nuts and they were tight, but the axle nut had backed out several threads.

So today I pulled both wheels off and took a look to confirm which hub had been worked on. The left looks new while the right looks original with original yellow torque paint on bolt and original tape on hole.

The new hub has a much deeper well than old: the axle nut goes on much farther than on old hub. I have maybe 3/4 inch of threads showing on the new hub.

Anyone have good dimensions for Jaguar parts versus Eurospare hubs?

I will go see the local guy on Monday and see what he says.

The OE LH Hub Carrier MJA3291AA is listed as fitting XK8 1997-2006. The 'R' performance models have a different P/N (MXD3291AA). As your LH and RH are different, has he fitted an OE equivalent to the correct part?

A new hub was an expensive way to fix a bearing issue!

they replaced item 1, along with wheel bearings and seals in a kit QWB708
they called item 1 the hub assy.
the nut had backed off several threads causing the wobble the in tire and impinging the rotor on the carrier resulting in scoring of the rotor

 

I understand now - the hub and bearings, not the hub carrier.

After correct shimming on the bearings, the hub nut is finally tightened to a massive 304Nm so it's amazing it has backed off.

Unless they reused the nut.

 

Yes -as RJ237 says. the nut has a sort of helicoil type insert which is single use only. Even thought the assembly torque is massive, it can come undone if reused.

 

They billed me for a nut. Here are pics of original right rear, closeup of nut, replaced left rear, closeup of nut, and damage to rotor. The new hub has a much deeper well. Is that correct?
