NOTE: The SRT-10 vehicle is not equipped with
front brake dust shields.
NOTE: Components attached with a nut must be
torqued to specification.
NOTE: Suspension components with rubber/ure-
thane bushings should be tightened with the vehi-
cle at normal ride height. It is important to have
the springs supporting the weight of the vehicle
when the fasteners are torqued. If springs are not
at their normal ride position, vehicle ride comfort
could be affected and premature bushing wear
may occur.
CONTROL ARMS
The upper control arm bolts on frame brackets. The
frame brackets have slotted holes which allow the
arms to be adjusted for caster and camber.
The lower control arms bolt to the lower frame brackets and pivots through bushings.
The control arms have lube for life ball studs. The control arm travel (jounce) is limited through the use of rubber/
urethane bumpers. Rebound travel is limited by the shock absorber.
Having the suspension at curb ride height when torquing bolts ensures good ride characteristics and longer bushing
life by preventing excessive
