Hello all. One of the back wheels has a bit of movement. If i put my hands at 3 oclock and 9 oclock and try to wobble the wheel there is zero movement. If i hold it at 12 oclock and 6 oclock then there is some movement.
Any ideas?

 

Presume the centre lock wheel is tight on the spline then it's bearing wear & a hub that needs new bearings, re-shimming & setting.

 

Hi Glen. The centre lock is very tight.
I would have agreed with you on bearing IF the movement had been in all directions but as I mentioned there is absolutely zero movement if your place your hands at the 3&9 oclock positions and try to wobble the wheel - its tight.
The fact that it only has movement in one plane makes me think it is not the wheel bearings. Or do you disagree? If so what is your thinking that could cause such a specific plane of movement?
Cheers

 

While you do not want excessive wheel movement, some, is actually a product of the factory specified end float of 0.002 – 0.006 inch. The 0.006 inch can appear very excessive at the wheel rim.

I would suggest setting up a DTI gauge on the hub and checking the end float before making any decisions.

 

If it's only at 12 and 6 o'clock I would check the driveshaft joints and the lower arm bearings.

I would be surprised if it's a wheel bearing with no play at 9 and 3 o'clock.

 

You have to check whether the movement is in relation to the bearing housing/hub carrier or not. Otherwise as others have stated it could be play in one plane in the suspension. However it is not impossible that the bearing races have worn slightly oval due to loading. They do over time & people are careless about greasing the hubs..

 

Ahh, interesting. I didnt realise that could happen. Thanks Glen

 

Just for further clarity I'm talking about uneven wear of the fixed races in the hub carrier.
