made by using a (M10 x 1.5 - 6H) thread chasing tap
on the holes to restore the threads to a usable condi-
tion. If threads can be restored to a usable condition,
install sway bar retainer attaching bolts and torque
to 68 N Im (50 ft. lbs.).
CAUTION: When performing repair procedure listed
below. Be sure replacement bolts and nuts meet the
same requirements as the original equipment man-
ufactures specifications.
If damage to threaded holes in lower control arm,
can not be restored to a usable condition using the
above procedure. Drill out holes in lower control arm
using an 11 mm drill bit. Then use a bolt and nut for
attachment of sway bar retainer to lower control
arm. Torque the nut and bolt to 68 N Im (50 ft. lbs.).
REMOVAL
(1) Raise and support the vehicle. See Hoisting in
Lubrication and Maintenance, Group 0. (2) Remove the bolts and sway bar retainers at the
front lower control arms (Fig. 16). (3) Remove the bolts at sway bar crossmember
clamps, and remove clamps and sway bar from vehi-
cle (Fig. 16).
INSPECTION
Inspect for broken or distorted clamps, retainers,
and bushings. If bushing replacement is required, the
inner bushing can be removed by opening the split.
The outer bushing must be cut or hammered off the
bar. If replaced, the outer bushings should be forced
on so that approximately 1/2 inch of the bar pro-
trudes. The sway bar to crossmember bushings, should be positioned when installed, so the void on the
bushing is positioned toward the rear of the vehicle
(Fig. 17). Note that the control arm retainers are
symmetric and bend slightly upon installation.
INSTALLATION
(1) If inspection of the sway bar assembly, deter-
mined that sway bar to lower control arm bushings
require replacement. Install the new bushings, by
forcing them onto sway bar using a rotating motion.
Bushings should be installed on sway bar so that sway
bar extends 1/2 inch out past the end of the bushing. (2) If required position sway bar to crossmember
bushings on sway bar with external rib up and void in
the bushing facing the rear of vehicle (Fig. 17). Lift the
bar assembly into the crossmember, and install

KNUCKLE (FRONT SUSPENSION)
The front suspension knuckle (Fig. 1) provides for
steering control of the vehicle. Supports the brake
caliper and absorbs the loads exerted during vehicle
braking. It also supports the front (driving) hub and
bearing and stub axle assembly. The front suspension knuckle also provides the abil-
ity to align the front wheels of the vehicle. This is done
by allowing for front wheel camber adjustment and the
ability for front tire Toe adjustments The front suspension knuckle is not a serviceable
component. Do not attempt to straighten or repair the
front suspension knuckle in any way. Service repair or replacement of the front (drive) hub
and bearing, can be done with the front suspension
knuckle remaining on the vehicle.
REMOVAL
(1) Remove the cotter pin, hub nut lock and spring
washer from the front axle (Fig. 2). (2) Loosen hub nut while the vehicle is on the floor
with the brakes applied (Fig. 3). The hub and drive-
shaft are splined together through the knuckle
(bearing) and retained by the hub nut. (3) Raise and support the vehicle. See Hoisting in
Lubrication and Maintenance, Group 0. (4) Remove the wheel lug nuts, front tire and
wheel assembly and hub nut and washer. (5) Remove the brake caliper adapter to steering
knuckle attaching bolts and washers (Fig. 1). Re-
move the brake caliper and adapter from the steering
knuckle and braking disc. Support brake caliper/
adapter assembly using a wire hook and not by hy-
draulic hose (Fig. 4). (6) Remove the braking disc from the front hub/
bearing assembly (Fig. 5). (7) Remove the cotter pin and nut from the tie rod
end. Remove the tie rod end from the steering
knuckle arm using Puller, Special Tool C-3894-A
(Fig. 6). (8) Remove the clamp nut and bolt (Fig. 7) secur-
ing the ball joint stud into the steering knuckle. (9) Separate ball joint stud from knuckle assembly
by prying down on lower control arm. Pull knuckle
assembly out and away from driveshaft (Fig. 8).
