CAUTION: Ensure there is NO gap between the anti-vibration bracket and trailing
arm while tightening the control arm nuts and caliper mounting bolts.
Any clearance may cause the anti-vibration bracket not to seat properly
and may create a brake caliper to anti-vibration bracket clearance
concern.
12. Thread the upper and lower control arm nuts (2) fully onto the bolts until no clearance
remains between the nuts, anti-vibration bracket, and trailing arm. Do not tighten the
nuts at this time (Fig. 4).
NOTE: The upper and lower control arm bolts/nuts will be tightened to specification
at the end of the service procedure once the vehicle is resting at curb height
in order to prevent preloading of the control arm bushings.
13. Tighten the caliper anchor mounting bolts (1) to 68 N•m (50 ft. lbs.) (Fig. 4).
14. Repeat the anti-vibration bracket installation process Step #3 through Step #13 for the
opposite side before continuing to Step #15. Installation of both right and left
