Yes, bought the Bearing and seal kit from Island 4x4. They are all Timken bearings. I think "Nodge" put a very good post up on here some time ago.
The diff is heavy and an extra pair of hands is essential, especially if doing the job without a powerlift & transmission jack.
The bearings on the crown wheel went on mine but the pinion bearings were ok but decided to replace the lot.
You will need split bearing separator and a good set of pullers together with a soft drift (Brass, Copper etc)
Access to a hydraulic press would be a great help. Relocated to Mid France from N. Wales March 2021

From what I read on here, most people change only the crown wheel taper roller bearings and seals, which is relatively easy. The pinion bearing rarely fails and is more difficult to change and set correctly.
I opted to change the complete diff, I picked up a used one from a range Rover sport with only 50K miles, cost me £90 delivered from *bay. I opened it it to check and it was like new inside, so I just fitted new seals.
My breather was blocked, so I replaced it with the new update version, this seems to be the root cause of bearing failures as it causes condensation to form inside the diff.
The diffs between RRS & D4 are interchangeable as long as you get the correct auto/manual version for the Auto 6 speed box 2005 TDV6 SE Auto

I did all the bearings in my rear diff. If you have a failing bearing the debris will be damaging the pinion bearings. Personally I’d do all of them. Series one 1949 - in bits, chassis is strapped to the ceiling in my garage (beside the canoe)
