    respectfully, I disagree with that, on the rear diff, that is a precise symptom, but only when turning to the right if I recall. I had the same problem, which was cured with a rear locking diff rebuild. When cornering, wheels spin at different speeds, so that and gear meshing may be stresses further is all I can figure.

    Kind Regards

    Diff was replaced earlier and it didn't stop the noise, only went after lower control arms were replaced so ?? Can only go on what I know. I don't have any problems now, Cheers though, all comments are welcome and a broader train of thought helps everyone.

    T/C bearings where at fault in the end.... they replaced all of them plus the flanges on the T/C. The noise has pretty much gone now and we've been left with a slightly noisy front diff that I'll have to keep an eye on for dad. Will need to do the bearings in it before too long though.

    The testing + rebuild ended up costing around the $2,200 mark with the kit for the t/c alone coming in at around $750. Not too happy since the car has only done 120k km and has had an easy life but glad to have it rebuilt instead of getting a replacement [2nd hand was $2,200 + fitting and that's not rebuilt]

    Anyone wondering about the testing procedure there is a LR internal bulletin about it and it tells you to remove the drive shafts and see if it still makes the noise.... let me say that once the drive shafts where removed the damn T/C sounded pretty much like a whale in mating season!!!!

    Was there any suggestion as to why the bearings went - foreign matter or poor bearings? Did the kit include the bearings or were you able to obtain other bearings?

    The kit included everything.

    It is believed that the center bearing on the tailshaft went which lead to excess strain on the rear output shaft which did its bearing which then did damage to the other bearings inside the T/C.
