No I haven't tried that. Only had a 3 month warranty and that's ended.
You say in your opinion the bearing is too small, then go on to say the bearing is cheap. What manufacturer bearings do they use? Cheap and undersize (for the pressure applied) need to be considered separately. A high quality bearing will fail if it's used in circumstances where too higher a force is applied to it, as it's not rated for that load.Landrover say the pinion bearing damage is attributed to the way in which the coupling applies torque when moving away from standstill or during slow-speed manoeuvring, the reflash changes this. Personally i don't see this as being the main issue, the problem is the bearing is simply too small which is magnified by the use of cheaper quality bearings. The only fix without a new design of casing to take a larger bearing is to have the harder higher quality bearing kit fitted, and ensure the diff is rebuilt properly with the correct preload and backlash. That said, if you have a haldex 4 you may as well have the reflash too, as long as the dealer doesnt want to sting you for it.
FL2 rear diff problems have been going on since the FL2 started. LR has paid out a small fortune to fix/replace them world wide as well as paying out towards partial costs for those just out of warranty. It's damaged the FL2 reliability figures severely. Taking into account LR's technical ability and the fact it's often the case failed items are paid/partially paid for by the builder (not always LR) I just don't see how LR and it's builder would miss the opportunity to fit a larger bearing if this is a viable fix to solve the problem long term. If a magic fix was that easy then surely they would have been doing this years ago on new build production? Especially when considering how easy it is to take back a LR product for warranty repair if the dash squeaks etc.To check the diff for noise, get some one to drive while you sit in the centre of the back seat, when up to speed stick you head into the boot area, its pretty obvious when the noise is coming from the centre of the boot and gets amplified in the boot space. The problem with these diffs is the pinion bearing is too small, even if the car was done under warranty in the first 3 years, it will most likely go again within 30-70k miles (depending if you have a 07-08 or 09+ - early ones last longer). We have now devised a method of modifying the diff to fit a larger bearing that can withstand an extra 25% loading. Id say at least 50% of the failed diffs im seeing now have already been rebuilt at least once using the standard bearing, although id say 25% of them have failed due to them being rebuilt badly rather than it being the bearings fault
Thanks I assume it would have been built in march or April 2010. Quite honestly I have been kind of looking at prices over the last 6 months but when I saw this one it was like looking at a brand new vehicle in the showroom so I just went for it. I will just keep an eye on the diff or should I say an ear on it, I have a defender 90 TD5 so mending Land Rovers is nothing new to me.Hi Raywin
I don't know when they fitted the upgrade but mine was registered in Nov 09 which was before the upgrade but having said that it did 81000mls before it needed repairing so you have a way to go. I have done 5000 miles since the repair in March '16 and no problems. Love the car
As the murpy law teachs I'm in the situation you describe.id be wary driving it that far home, the juddering is the haldex locking up the transmission , hence why you only feel it on turns (axle speed differences). I would suggest you either unplug the Haldex unit (under the car you will see 2 plugs going into the Haldex units ECU, uplug the larger of the 2) or remove the Haldex fuse from the boot box fuse box, fuse FB6, this will disable the unit and you will be running in FWD only. You will get a transmission fault error come up on the dash if you do this but dont worry about that. Personally i like to unplug the unit completely. If it is the pump, a failing pump draws a higher current, for some reason landrover fitted a 15amp fuse to this circuit, whereas a good motor only draws 3 amps, the failing pump draws alot more (but less than 15amp) and can actually damage the Haldex ECU circuit boards(bad thing!)
