Diagnosis needed part II

[lhd]

Whilst adjusting the rear brakes I noticed that when turning the wheel by hand the driveshaft seems to move towards the gearbox once on every turn.
This was very easy to see at the gearbox front mount as it moves too and throw on rotation in the same spot, it actually moves the whole box over about 3 to five ml. The other side is fine.

Well its not the CV joint, changed the outer and without connecting the inner the problems still there. There is about ½ mm play to and throw on the hub but considering the shaft is moving 5mm I doubt it's that.....
Could it be a bent axel shaft?

What do you think?

I may be wrong but wouldn't that would have been destroying CV joints ?

The one I took off had a lot of wear to the cage, see below...

Apart from the cage everything else looked like brand new not a blemish....

not that i helps but it is the case that is the weak point, it bearings are very very strong,

The one that I took off last week (which was clicking) had evenly an worn cage and some polishing to the outer race. Nothing as bad as that.

Could be a bent driveshaft by the sounds of it

I doubt it Phill.... when I look at the CV boot (trailing arm side) it's moving in and out about 5mm, I think it's something to do with the hub assembly.
The shaft would have to be so bad that it would be pretty obvious,eapecially as I have had the shaft off.
If I could only see the too and throw at the oposite end of the shaft I would agree.
I don't think it's the wheel bearing as the hub with the studs turns freely when the drive shaft is removed, there is about ½mm play when pulling the hub it in and out, but even that wouldn't account for 5mm at the boot (trailing arm side).
I did have spacers on my 9 Inch wide wheels to get flat caps on my Borbets and looking from the rear there was a massive camber, so bad that the tyres wore nearly bald on the inside of the tyres, which was why I removed the spacers and ditched the flat caps.
I'm wondering if a big pothole or something bent the axel shaft?

Not unless you've got no suspension mate. I view on the upcoming trip I'd be inclined to get a new hub sourced and fitted. Where and when were the last set of rear bearings fitted ? Could the hub be worn and the bearings not aligned correctly ?
