The pinch bolt is not there to remove the up and down play
from worn out rack bushings. It has more to do with steering
wheel feel and free play between the rack and the pinion.
From underneath grab the dust boot and firmly push up
and pull down to check for worn rack bushings. This is the bushing
inside the dust boot that holds the rack. Not to be confused with
the bushings that mount the rack to the firewall. This inner bushing
will not show up on the 12-6 and 3-9 tire wiggle test as there is
nothing in that test that will make the end of the rack go up and
down. Going over bumps can make it pop from top to bottom.
Another over looked part when putting in new struts or any time a
noise like this is present, Upper bearing plates are generally reused
and look just fine, but the rubber and metal that the strut nut tightens
down on can come loose and make a racket on bumps. Can also make
steering effort excessive.
