Technical Background
The noises are caused by the rubber metal bushing of the
control arm (Figure 1). The rubber lib of the rubber metal
mounting rubs on the collar of the inner wishbone sleeve.
The resulting stick-slip effect causes the noise which does
not affect the service life and function of the components.
This is a normal condition.
Note:
Track control arm bushings that are completely cracked
through should be replaced.
Figure 1. Arrows point to bushings.
