Welcome to the forum Sherard Big Daddy,

I've moved your question from General Tech Help to XK8/XKR forum. US based members here with the same model will be able to help.

Please follow this link New Member Area - Intro a MUST - Jaguar Forums - Jaguar Enthusiasts Forum to the New Member Area - Intro a MUST forum and post some info about yourself and your vehicle for all members to see. In return you'll get a proper welcome and some useful advice about posting to the forum.

Actually, you moved it to the XK/XKR forum, which was correct.

 

Try to look at it with a positive spin, this is the perfect time to fit an LSD!

Have a look in this thread ==> https://www.jaguarforums.com/forum/j...ntials-134733/

Your XKR has a 3.31:1 ratio diff which was also used in the S-Type, X350 XJ, early XF's and even the Lincoln LS & Thunderbird.

Hopefully that might help you in finding a second hand unit. In that thread I mention which engines of which models got which ratio's.

If you have a capable workshop nearby then I would also suggest taking the diff and driveshafts from a 1999-2002 S-Type (3.31:1), fitting a Ford 8.8" LSD to that diff, and having your workshop sort out the driveshaft lengths.

Will be much cheaper in the end than the $7000 or whatever Jaguar insists for the upgrade kit to the GKN differential, which is still an open-center.

Good luck with it.

 

At one time, I posted notice of a bulletin dealing with
excess sand in the differential. The diffs were to be
replaced. But, there was an expiry date.

Even so, a case might be made that if the bulletin
existed, and the damage is a result of the same
condition that it should be covered.

 

What exactly is going bad? If it's just the bearings it's easy to do. Depends on how handy you are. Atlanta Driveline in Norcross will rebuild it for $400 but you have to bring them just the diff. You can use this tutorial to swap out the bearings. You'll just have to cut off or use a press to get off the old bearings.

If you can get it out yourself you'll save a ton of money. I'm in Atlanta if you'd like to PM me.
