INSPECTION
Inspect for evidence of fluid running from the up-
per end of the reservoir. (Actual leakage will be a
stream of fluid running down the side and dripping
off lower end of unit). A slight amount of seepage be-
tween the strut rod and strut shaft seal is not un-
usual and does not affect performance of the strut
assembly.
INSTALLATION
(1) Install unit into fender reinforcement and in-
stall retaining nuts and washer assemblies (Fig. 1).
Tighten the 3 nuts to 27 N Im (20 ft. lbs.) torque.
(2) Position steering knuckle neck into strut as-
sembly. Position washer plate and install cam and
knuckle bolts (Fig. 4). (3) Attach brake hose retainer to damper, tighten
the screw to 13 N Im (10 ft. lbs.) torque (Fig. 4).
(4) Index strut to original outline on the knuckle
neck, or align mark on cam bolt with the mark that
was put on the strut to steering knuckle bracket
(Fig. 4). (5) Plac e a 4 inch (or larger) C clamp on the strut
and knuckle as shown in (Fig. 5). Tighten the clamp
just enough to eliminate any looseness between the
knuckle and the strut. Check alignment of the index marks and tighten the bolts to 100 N
Im (75 ft. lbs.)
plus 1/4 turn beyond specified torque. Remove the
(C) clamp.
(6) Install wheel and tire assembly. Tighten the

tighten all retainer attaching bolts to 70 N Im (50 ft.
lbs.) torque. (5) Lower vehicle.
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.

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

to the road surface. While being able to twist as one
wheel moves vertically with respect to the other.Roll resistance is provided partly by the axle's re-
sistance to twist. But primarily by a torque tube or
rod (depending on the suspension option called for)
running through the channel and attached rigidly to
its end plates by welding. Because the torque tube/
rod is an integral part of the axle assembly, it cannot
be individually replaced. The spindles are bolted to the axle end (spindle
mounting) plates and can be individually replaced if
required. Rear wheel alignment changes require the
use of shims between the spindle and axle end plates.
