Pinion bearing replacement 2003 XKR

![Default](/forum/images/icons/icon1.gif)
Hi folks,
went to my mechanic with the car, put it up on a lift with car in drive, to investigate the noise I am having from the rear end. I previously had a thread called "Wheel bearing noise", but have since learned that it is the diff that is making the noise.
After listening with a stethoscope, mechanic is pretty sure that it is the pinion bearing that has gone bad, even though there is no play whatsoever in the driveshaft. He recommends me to replace the bearing, praying that it hasn't damaged the differential yet. The only issue, he said, is that there are no instructions from Jaguar on how to replace the bearing. You can buy the parts required (about 200 EUR) however.
Anyone with experience/instructions on how to replace this bearing?

This was one of the few tasks I left up to my indy. I only needed the seal (which you can apparently get from Coventry West) but Jaguar doesn't sell them separately, and since my indy only uses OEM parts, I got the bearing and the seal. If anyone needs a used bearing without the seal, I'll gladly ship it to him for cost of shipping. I'd rather not ship overseas though.

Getting too and removing the pinion bearing is straightforward. Getting the new one properly aligned and seated is the rub. A major factor is not over stressing the crush sleeve. If you do your back to square one. One of the Jag techs on the FORUM should be able to walk you or your indy through the process. Also, do a search on YouTube for replacing differential pinion bearing and a general web search for same. I have often found these sources to at least provide a good general familiarization with diverse subject matter.

So can one actually remove the pinion and bearing in place, without removing the entire differential? Just wondering how much I should expect to pay (hours) for this kind of job.

This is just the seal: NEW PRODUCTS
Part way down the page, Part Number: JLM-20602/SEAL
If you buy directly from Jaguar, the seal and bearing come together. I left it in my parents garage, otherwise I would give you the part number off of it.
EDIT: Part number is C2N2581 per my receipt. With new fluid and labor my total came in just over $500 from my indy.

So, can the diff stay in place when this operation is done, or do you have to take it out completely? My mechanic told me it would be about 6 hours to replace a diff.

Unfortunately I don't know of any differential experts around here. If I manage to find one, perhaps there are some send-in rebuild options available. Where are you located, avos?

You might want to put in a second hand one, as long as you are sure it is ok (i.e. not noisy), if you are not interested in a LSD yet. You see lots of diffs for sale in the UK for about 200 gbp.
I only know 1 company in the Netherlands (AenR) who can do it, this is thier main business including transmission rebuilds.
PS As the full rear end has to be removed to take out the diff, it’s also a good time to replace all the bushes if that hasn't been done yet.

Good advice, I'll make sure to have that done as well!

All XK8/R models are the same (except the XK8 Mexican market as it has a different rear end ratio). The XJ8/R are slightly different, and some have a different gear ratio, like the 3.2 for instance.
The difference I can see with the XJ versions is the flange on the pinion, but I wouldn’t be surprised if you could just swap that. Maybe someone can confirm this. It also looks as if the pin of the pinion sticks out more, but that can be cut of off course.
