Are the wheels properly (dynamically) balanced?

I agree about the wheel balancing , they are very sensitive. Badly balanced wheels can give a "funny vagueness" at the steering wheel, but as Karl suggests, it isn't just the wheel itself, you need to consider the wheel/drum combined - is it better or worse if you refit the wheel at 90 or 180 on the drum ?

The brakes do tend to pull a little on light application especially if you have fitted new linings as well.    It is not anything to worry about.   The wheel wobble at only 10mph does sound much more like pillar wear than balance which only tends to come on over 40mph.   It is difficult to test the pillars for slack as if you jack the car up to free the wheel the pillar is then at the very (unworn) end of its travel - I used to get my Lambda through its MOT using this trick.   Try heaving on the top of the wheel when the car is sitting normally.

Thanks for the comments... i will move the wheels round through 90 degrees to check, but suspect that's not the issue as the tyres are new and the wheels are recently balanced and its occurring at a low speed.  I think it may be the sliding pillar and in particular suspect the bearing that allows the pillar to rotate...will try another test drive now the weather has cleared...
