I have a leak out of the bearing on the driver side of my differential, along with a quiet humming noise while driving. Can someone tell me what kind of bearing I need to buy? I've searched the net and I found some from the $14-$40 range and then another kind of bearing for just under $400. What kind do I need? Inner or outer? Do I need a seal too?

Welcome to the forum dreyco!

The diff seals are available to buy from Jaguar (the ones that seal to the outside of the diff case) but the bearings are not.

I recently had the diff in my 2005 XJR rebuilt (at the same time as fitting an LSD) and I bought a bearing & seal kit from the supplier in the UK who sold me the LSD.

Unfortunately I didn't write down the part numbers of the bearings, I only took a photo...



You can see the part numbers for the seals on the bags, there are four bearings, 2x from Koyo, 1x from Timken and the other came without a box...

The Koyo ones are for the sides of the diff center, the Timken and other are for the pinion.

Try contacting TL Jaguar or Racing Green in the UK. I also remember seeing a website of a company in the US that fitted a Quaife to an X150 XKR (has the same diff) and they found the bearings needed.

 

Hi any news with part numbers? Thank a lot!

 

Hey Pavel,

The bearings were identified as generic Ford bearings, same as the Lincoln LS and a few others.

The part number for the bearings is in this thread https://www.jaguarforums.com/forum/x...arings-102296/

I got your message on the other forum, please go to this thread https://www.jaguarforums.com/forum/g...ids-sdd-77299/ and continue the discussion there, very interested to know how the ratio swap went, and if your guy will be able to reprogram the ZF transmission, he's not in Bulgaria is he?

Thanks, I've finally found the numbers and will update that thread. The guy is in Czech Republic.

 

Very keen to see how this turns out!
