Anyone have any info on doing this on the X300?

 

Hi Juliesjag69,

I assume you're talking about one of the rear hub bearings, Part 3 or Part 9 or both in the diagram below? Part 8 is the Hub Carrier and Jaguar Classic Parts lists the bearings as Hub Bearings, which are also commonly called Rear Wheel Bearings:



If those are the ones you're looking for, below are links to photos of the replacement job on our '93 XJ40, which is essentially identical to your X300. The job isn't difficult, just take very seriously Jaguar's warning to use new axle nuts because they are only good for one use, and you'll need a torque wrench capable of setting those nuts at 221-236 ft. lbs.:

Superb reply, excellent info Don, thanks for sharing

 

Unfortunately no its parts 13 thro to 18 listed as the hub carrier bearings. Mainly number 15.

 

Sometimes the bolt (13) becomes seized in the carrier. Note at the opposite end, towards the rear, you may have a bolt head instead of a thread. Clean the head carefully and you may see a small mark. This is for adjusting the toe-in. Take note of this as you may need it for setup afterwards. Get something like a small extension or bolt of same diameter and hit the bolt (13) carefully out towards the rear of the car. Don't mix up the spacers (16)

 

What sort of job is it to change Bearing 15 tho.

 

Hi Juliesjag69,

In the links I sent earlier, Photo 7 in Album 1 and photo 3 in Album 4 show those bearings. Somewhere I got the "Hub Carrier Bearing" terminology too, because that's what I call them in my photo albums, but Jaguar Classic Parts and the Electronic Parts Catalog just call them "Taper Roller Bearings."

Replacing those is not usually difficult unless the pivot bolt and/or the pivot pin sleeve are corroded as overtheatlantic observed. Typically you don't even have to remove the hub from the car. What are the symptoms prompting you to need to replace those bearings?

Cheers,

Thanks Don, had the rear wheel off and noticed quite a lot of movement in the bearing mentioned.

 

Be careful after you change the bearing. The end float is the key, you will have to measure that with a gauge. IF there are no end float you will damage the bearing, so in that case you will have to change the spacer No. 16.
I forgot how much end float was appropriate, but that was stated in the workshop manual.
I will check when I have time, or maybe someone will help with that.

 

Actually, the X300 manuals call for a couple thou *pre-load* on the rear bearings. That is, less-than-zero clearance; no end float at all.

Near as I can tell almost nobody goes thru the process of checking and setting up the pre-load. Presumably replacement bearings are all so close in size that merely reassembling all the parts gets them close enough to spec.

Some better replies guys thanks. will get on with it now.

 

Hello,

Doing this job now and all the clickable links to the photos are broken.

Thanks,

Hi Leo,

Unfortunately the Jag-Lovers forum has been in the process of transferring images and other data to a new server for a couple of years now, and most of the large images are still unavailable. Only the thumbnails are visible. Uploading all those images took me countless hours and unfortunately I haven't had time to upload them again to the Jaguar Forums. Maybe someday! Good luck with your bearings. I'm sure you'll do fine.

Cheers,

Don
