Jack up car at back with hand break off, grab wheel at top and bottom and
pull back and forth, there should be no play in the suspension other than
the direction it is supposed to move in. As long as all bushes at joints
are intact (ie no splits or cracks) it should pass ok. Give wheel a spin
while it is up to check wheel bearing. Mine recently failed on the rear
tie bar (short rod about 10" long) bushes were fine but wheel had a side
to side movement of a couple of mm, rod had to be replaced as holes for
bushes had become oval! (too much high speed cornering) Hope this helps?!
