I'm a bit tripped out.

Both rear wheels have tiny amount of movement (when jacked up of course) if i rock the wheel with one hand at the top and other hand at the bottom. (vertical plane)

However! there is no movement if i try to rock the wheel with a hand either side (horizontal plane). If i rotate the wheels 90 degrees, the moment still remains in the vertical plane.

Its very very small, but there. Is this something normal? bearings aren't all that old either.

thanks

they just may need re tightening

Am I to assume you have an IRS (double jointed) rear end?
If that is the case then that is normal. The rear bearings have no preload and it is the weight of the wheel that makes this evident. If you were to put a dial gauge on the horizontal plane you will see it too has movement, but the weight of the wheel makes if hard to 'feel'...

Cheers Dave

Thanks David, yea i have the double jointed rear end. Schweet, i can sleep soundly now .
