Thread: Rear diff question

Sounds like your one of the lucky ones Doug being replaced under warranty. I wonder if towing had anything to do with it like inside says too much preload on the pinion bearing. Myself and Richard93Vogue are still on the original with higher Klms (sound like our cars are very similar in age and condition) and yours and mikehzz have gone early at about the approx the same Klms. Mikehzz have you ever towed or had reason for extra load??

Doug, you say parts aren't expensive but the dealers are charging $200 per hour!! I can understand the oils but wonder for those who aren't covered under warranty can have there own trusty mechanic to repair or is it a job for dealers only, Woko you might be able to give feedback on this one??

Is the preload bearing the most common cause of fault??

Sorry for all the questions guys but the forum has been quiet so thought I'd open it up and post something that a lot of owners tend to experience as a common fault and everyone's feedback might help someone in future :-)

Its not a difficult diff to rebearing. You would probably find that most mechanics would sublet out to a gearbox and diff specialist.

Only the front bearing, seals, collapsible spacer, nut is avaliable from Land Rover. But you can get kits from the UK with all bearings, seals etc.

I did have to modify a socket to do the job, but nothing unusual to do the job.

Oil for the haldex you will need to get from Land Rover

My personal opinion on bearing failure on these is a combination of poor bearing quality and not enough oil at the correct level. Both front pinion bearings that I had removed were made in India. The filling of these is to fill to the level plug and then remove a certain amount of oil. I left mine at the fill plug.

Are the diffs serviceable or are they a sealed unit?? Is there anything we can do as preventative maintenance, what do you think??

Freemander, the topix web site has a service bulletin on the diff problem and the cause is what they call static overloading. It is a well documented warranty issue in FL2 vechicles between vin000212 and vin257090 . The pinion bearing and seal repair could be done by any competent mechanic ,however there is a software upgrade for those vechicles fitted with gen4 haldex units which were fitted at the start of my2009 manufacturing run.
With mine the noise started slowly(?) but is now very noticable .Maybe if you suspect a problem it might be worth getting in contact with LR Aust because the problem is well documented and aknowledged as a problem .

Thanks Doug, that's very useful information and good to know. Mines running great with no noise but knowing that it may appear in the lifetime I have the car, it's good to know there is info out here, and for the benefit of others.

Changing the oil is the only maintenance you can do. There's no drain in them but easily sucked out to change the oil

I was on holidays last week and while driving got a "Transmission Fault - Traction Reduced" warning. no noise from the back end at all.

Local mechanic who knows the issue with the Haldex plugged in the computer ad advised that it wold cost me $1000 to replace some parts that may solve the problem. He said that to ensure it doesn't happen again I wold need to change the complete unit $4500 + fitting.

For the last 2 days I havent had the warning and it is working fine. Mechanic says that that is part of the issue, the problem is intermittent.
