out. If relative movement is observed between
brake disc cover and end of transverse link, ball
joint may be excessively worn.
3) Next, grasp the end of transverse link and move
it up and down. Relative movement between hous-
ing and transverse link boss indicates ball joint may

4) If the relative movement is observed in the im-
mediately preceding two steps, remove and inspect
the ball joint. If the free play exceeds standard, re-
place the ball joint. <Ref. to FS-19, Front Ball
