Hi,folks!Now i try "to give" something to forum,not only take!
If your xj40 or x300 haves noisy rear probably it's time to replace this bearings. 120k miles is maximum for them (i read it at this forum). My car starts to noise at 50mph(80kmh) AND after 10 minutes driving. Mysteriuos quiet 10 minutes.
But don't be hurry to change them, diagnose firstly wheel bearings!
.....
When you take off wheel you can see this 4 nuts at the output shaft. Unbolt them. I stopped rotation by handbrake.



Now you can pull shaft and see this:

Then i saw "V"-letter (Vasen(fin.)-left hand) here i understood, i'am not first, who change outshaft bearings. But my car haves 134k miles at odometer

after take off this speed sensor ring


behind it are 5 bolts to the diff. Unbolt them all.


Pull whole construction from diff.

Atention! Be carefull with this metric rings (in my hand). Don't mix up rigts & lefts, they are differents!

Then i destroyed collar. You can also to drill it, how it said at manual. So-destroy is creative job



I haved interest why bearing is noisy and destroyed it too. So



Now i waiting for bearing kit from Germany. To be continued...

 

Hi Yari, Thanks for the photographs. My XJ40 has done 90,000 miles and the diff is noisy. I am replacing the output bearings soon. I also have an XKR but I prefer my lovely XJ40 to drive, it is as good as a Rolls Royce. Cheers, Dave.

 

I happy to find out my photos helpful for someone!!!
Now i'm just driving,driving & driving my xj40 in hard russian enviropment about every day)))So,i collected some of works for winter aint & leather scratches, interior wood issue , tires are worn out, suspension knocking.
I like my "budgetary RR" too!!!!I'll rapair with care))

 

Nicely done! I wish I had more time to tinker with my differential. You make it look so easy!

 

Thanks!

That first photo shows a very interesting way of getting at the flange nuts. Lots of people try to get in there from underneath.

Is that bearing not supposed to be splash lubricated by the gear oil? At least in theory?

(those brake pads look a liitle thin)

 

Thanks Yari
This really, really helps me out.

Hi Snowball,

In addition to Yari's excellent photos on removing the differential output shafts, below are links to photos showing the full process of replacing the bearings, seals and retaining collars once the shafts are out of the car. Check my other photo albums for additional differential work.

Thanks Yari and Don B for your excellent posts up-thread. I followed your instructions yesterday and successfully replaced the bearings and seals on my X300.

A couple of notes on the X300:

1. There's a spacer ring between the output shaft and drive shaft which is easily removed, allowing access with a socket to the Torx bolts holding in the output shaft assembly. Don't do what I did and assume it's attached to the assembly and try and remove the Torx bolts with a star spanner.

2. You'll need an E12 Torx socket to get the output shaft assemblies off. Yari's method of daisy chaining socket extensions works a treat for both these and the driveshaft nuts.

3. Lacking proper workshop tools, I managed to remove the collars using a cordless drill and subsequent cold-chiselling with the assembly held in a vice. I wrapped insulating tape round the drill bits to make sure I didn't drill through to the output shaft.

4. A short piece of scaffolding and a lump hammer makes a great tool for drifting on the bearings and collar (coupled with Don B's trick of freezing the shaft and heating up the bearing and collar).





Scaffolding drift

 

Bearing went on easily using my harbor freight 12 ton press. Collar not so much, got one halfway on and I could see my pipe I was using to install it start to bend on the lower edge. Going to get them pressed on by a machine shop and be done with it.
