That was my feeling too. It seems too much. I can't find play in the CV joints that I would expect given the amount of noise that is coming from the back end. The noise has also not reduced after adding grease to one of the CV joints.

If you are worried about the outer CV bolts rounding off simply take the whole driveshaft off and do it on a bench. With the shaft out you can easily test the rear bearings for 'grittyness'. If it is the bearings that are gone then you may as well regrease the CVs on both ends of the shaft while you are in there ...

Yes seen that. Mine is not that bad. But I'd rather change the wheel bearing if that is causing the noise.

My main worry is doing the CV joints and then discovering that the wheel bearings are what is making the noise. Not that it is a bad idea to clean the CV joints and put new boots on them at the same time as fixing the wheel bearing.

When you wiggled the wheel did you have the hand break off? if not try it like that.

Yes, that was with the handbrake off. With the handbrake on there was no play in the wheel at all.

Jed, how long is your bit of scaffold pipe? I'm using one about 1.5m long and even standing and bobbing up and down on the end of the pipe doesn't crack the nut. Given that I weigh 80kg, the torque I am applying should be 80x9.81x1.5 which is more than 1100Nm :shock:

E D I T: the 46mm surface drive socket is deforming the sides of the nut. That nut is not going to turn any time soon even with a longer bar. I don't have access to an oxy-acetelene set so I think I am going to have to (carefully) angle grind the nut off :|

You'll have to put on some weight !! :rofl

It has just move a whole millimetre (just after I ate my lunch :) ), but then stopped again. Off to get a gas burner and a new driveshaft nut. The 3/4" socket bar is bending under the force.

Have you definitely removed all of the split pin, there isn't any remaining un-noticed that is now jamming between nut and thread?

I bent and broke my power bar from my local motor factors, so I used Dibner engineering - a 6' scaffolding pipe with the 3/4" adaptor welded into the end - with heat and pies it shifted in the end.
