Thread: Drivetrain clunks

my rovers clunck as well I have been told that most of the backlash comes from the transfer case they need to have new thrust bearings fitted.

There are a lot of places where a little bit of slack is to be expected (splines in gearbox, transfer case, axles drive flanges, thrust washers in the centre and axle diffs) and small amounts can add up. There are also a few places where excessive slack can appear due to wear that needs to be fixed - gearbox main shaft onto T/C input gear, drive shaft bolts, drive shaft U-joints*, rear axle drive flanges, A-frame ball joint, lower link bushes, engine mounts, plus probably a few I have missed. But as a general rule, the slack is pretty much not noticeable unless driving technique is poor or the handbrake is dragging even slightly.

*check this and repair immediately if necessary, as it may lead to prop shaft failure, and you definitely do not want to find out what this involves!

I wish 75W-110 was readily available in Oz (yes, it is an SAE oil category) instead of having to mix your own.

Thanks again - would anyone be surprised (apart from me) if any mechanicals were worn out? The 110 isn't quite 1 year old.

Anyway - driving it home last night I managed to be pretty much clunk free. Reckon one needs to have some Zen happening to drive a LR properly.
