November 2007 GEM Service Manual
FRONT SUSPENSION
Fig. 5 Front Suspension System
1 - Front suspension frame
2 - Upper control arm
3 - Spring/shock absorber
4 - Knuckle
5 - Lower control arm
DESCRIPTION
The front suspension is designed to allow each
wheel to adapt to different road surfaces
independently. The wheels are mounted to rotor
assemblies, which in turn are mounted to the
steering components attached to a control arm, that
pivot up and down on bushings. Spring and shock
absorber assemblies at each yoke provide
cushioning.
CAUTION: Suspension components with
rubber/urethane bushings should be tightened
with the vehicle at normal ride height. It is
important to have the springs supporting the
weight of the vehicle when the fasteners are
tightened. This will maintain vehicle ride
comfort and prevent premature bushing wear.
