Rear diff pinion bearing

[woko]

My FL2 has developed the dreaded noise from the rear diff pinion. I have been given 2 rear diffs from FL2 and will rebuild one, I have a bearing kit coming from the UK and will post part numbers and bearing numbers to carry out this repair as only the front pinion bearing is available from LR. Will keep you posted

What mileage if I may ask?

I have received the rebuild kit. Here are the part numbers for seals etc.

LR002888 O ring
LR030846 O ring
LR023442 Seal
LR023440 Seal x2
LR023439 Nut
LR023443 Spacer
LR003136 Haldex oil (650ml required)

Bearing numbers

32008XJ Bearing x2 (Carrier)
30206J2/Q Bearing (front of Pinion)
HM88649 Bearing (rear of pinion)

You will also need a 41mm 12point socket that can go over a shaft 100mm long to undo the pinion nut and a dial torque wrench to measure the pinion torque for the preload on the bearings.

Will post Photos when I rebuild if anybody wants.

Hi, Many thanks for the info here and the photos.

I have the diff issue on a 2007 LR2 TD4 with 140,000km. I recently purchased the car, noticed the whine during the test drive and was reassured by the Land Rover specialist who was servicing it that he thought there was no issue with the diff or bearings and had never heard of a diff failing on a FL2.. From what I have read since any decent Land Rover mechanic should know better. Well that's history now and I am finding a new mechanic for the car.

Currently I have a few options, use my local mechanic who can do a diff swap for about $2,300 (rebuilt Landrover exchange) or take it to Landrover in case they can just undertake the repair listed above. If they can't it will be $2,600 for the exchange diff.

Does anyone have any info on whether they have had issues after a repair, that is that is issues with the casing, gears or sub components failing / creating noise? I am trying to gauge whether I should just bite the bullet and get the rebuilt exchange unit or take the chance that it may be repairable and will last. Thanks, Aleks

Ive done 6000km since changing just the front pinion bearing on a diff I was given and it is running well.
You say they are rebuild diffs, a rebuilt diff from LR would be no difference from yours being rebuilt.
Personally I believe the issue with the pinion bearings are they are cheap bearing that is made in India, They are a SKF bearing but made in India.

I haven't rebuilt the diff yet in the previous post.

Thank you for the reply, glad to hear that after 6000km still going well. The official word from Landrover on the bearing is the original Freelander 2 diffs had a pinion bearing that just wasn't rated for the static load that is put on it, basically a design mistake. As such they will all eventually fail. The new bearings provided for the rebuild have an upgraded bearing which can handle the load, so hopefully yours and whatever ends up going in my car lasts for a lot longer. Thanks again.

Hi woko,
Where did you find the procedure on how to rebuild the diff? My rear diff just started making noise and I can pick up a used diff in need of a new bearing fairly cheap. I just need tourqe and preload specs. Thanks Nate

there are a lot of service tools required. I had to modify a socket to undo the pinion nut. I could do the rest without the tools

Hi great info.

I'm having my diff rebuilt after pinion bearing failure. Bought kit FDK004 from uk seller on ebay for $230 delivered. Not sure how much labour will be as they are doing the job for the first time and are scratching round for/making tools as they go along. My question for anyone who has done this repair is this:

Should I be worried about the oil in the haldex unit being contaminated with metal filings ? There were bits all through the diff but all the gears look undamaged. We cant see inside the haldex however. They're going to check the oil filter etc. but id appreciate the benefit of any experience people may have. Obviously now is a good time to replace or repair any bits on the haldex unit while its sat on a bench, but if it is unlikely to have been affected then ill spend the money on feeding my family, alcohol or the like.

Thanks in advance

The haldex is sealed in a different compartment from the diff. The haldex uses a different oil and is dealer only and expensive.

Woko, once my diff goes I will hunt you down to assist, being in my neck of the woods and all .

Woko, I am getting ready to replace my bearing and the link above will not work for me. Is there a new link or something? Thanks.

Hi All,

Thank you so much for this thread. I used the part numbers provided by WOKO and bought them at the Landy Dealership here in SA. I bought Timken Bearings, removed the differential. (not very difficult)
Took the diff with the parts to a Gearbox and Diff rebuilder. I had to put in new axle oil as well as Haldex Oil. Got the whole job done for less than half what I was quoted and the Landy runs like a dream now.
So again, a BIG thanks for the info.

Getting the Haldex serviced is certainly a good idea, just remember that there are 2 filters in the Haldex, the obvious one and also a gauze filter which is accessible when you pull off the pump. When I serviced mine both were dirty but the gauze one was 3/4 blocked, which would have been restricting oil flow.
