JFRONT SUSPENSION AND AXLE 2 - 7

TOE POSITIONÐXJ VEHICLES
The wheel toe position adjustment should be the fi-
nal adjustment.
(1) Start the engine and turn wheels both ways be-
fore straightening the wheels. Secure the steering
wheel with the front wheels in the straight-ahead po-
sition.
(2) Loosen the adjustment sleeve clamp bolts (Fig.
4).
(3) Adjust the right wheel toe position with the
drag link. Turn the sleeve until the right wheel is at
specifications. Position the clamp bolts as shown
(Fig. 5) and tighten to 49 Nzm (36 ft. lbs.) torque.
Make sure the toe setting does not change dur-
ing clamp tightening.
(4) Adjust the left wheel toe position with the tie
rod. Turn the sleeve until the left wheel is at speci-
fications. Position the clamp bolts as shown (Fig. 5)
and tighten to 27 Nzm (20 ft. lbs.) torque.Make sure
the toe setting does not change during clamp
tightening.
(5) Verify the right toe setting.

TOE POSITIONÐYJ VEHICLES
The wheel toe position should be the final front
wheel alignment adjustment. In all instances follow
the equipment manufacturer's recommended proce-
dure.
(1) Secure the steering wheel with the front wheels
in the straight-ahead position. For vehicles equipped
with power steering, start the engine before straight-
ening the wheels.(2) Loosen the adjustment sleeve clamp bolts on
the tie rod (Fig. 6).
YJ Vehicles
The tie rod and adjustment sleeve have both
right and left hand threads to provide equal ad-
justment for each wheel.
(3) After the adjustment is completed, position the
tie rod adjustment sleeve clamp bolts as shown.
(4) Tighten the adjustment sleeve clamp bolts to
27 Nzm (20 ft. lbs.) torque.
(5) The steering wheel can be centered by the drag
link. Complete the adjustment. Position the drag link
clamp bolts as shown. Tighten the bolts to 49 Nzm
(36 ft. lbs.) torque.

SERVICE INFORMATION
CAUTION: Suspension components that use rubber
bushings should be tightened with the vehicle at
the normal height. It is important to have the
springs supporting the weight of the vehicle when
the fasteners are torqued. If the springs are not at
their normal ride position, vehicle ride comfort
could be affected along with premature bushing
wear. Rubber bushings must never be lubricated.

taining nut on the stud (Fig. 1).
(3) Remove the supports and lower the vehicle.
(4) Tighten the retaining bolt at the axle shaft
tube bracket to 100 Nzm (74 ft. lbs.) torque.
(5) Tighten the ball stud nut to 81 Nzm (60 ft. lbs.)
torque. Install a new cotter pin.

(2) Install the bolts and finger tighten the nuts
(Fig. 3).
(3) Remove support and lower the vehicle.
(4) Tighten the front and rear nuts to 115 Nzm (85
ft. lbs.) torque.
SPRING AND SHOCK DIAGNOSIS
A squeak noise from the shock absorber can be pro-
duced if movement between the rubber bushings and
the metal occurs. This noise can usually be stopped
by tightening the attaching nuts. If the squeak noisepersists, inspect for damaged and worn bushings, and
attaching components. Repair as necessary.
The shock absorber bushings do not require any
type of lubrication. Do not lubricate the bushings to
reduce bushing noise. Grease or mineral oil-base lu-
bricants will deteriorate the bushing rubber.
The shock absorbers are not refillable or adjust-
able. If a malfunction occurs, the shock absorber
must be replaced. To test a shock absorber, hold it in
an upright position and force the piston into and out
of the cylinder four or five times. The action through-
out each stroke should be smooth and even.
SHOCK ABSORBER
REMOVAL
(1) Remove the nut, retainer and grommet from
the upper stud in the engine compartment (Fig. 6).
(2) Remove the lower nuts and bolts from the axle
bracket (Fig. 6). Remove the shock absorber.
INSTALLATION
(1) Position the lower retainer and grommet on the
upper stud. Insert the shock absorber through the
shock tower hole.
(2) Install the lower bolts and nuts. Tighten nuts
to 19 Nzm (14 ft. lbs.) torque.
(3) Install the upper grommet and retainer on the
stud in the engine compartment. Install the nut and
tighten to 10 Nzm (8 ft. lbs.) torque.

SPRING AND SHOCK DIAGNOSIS
A squeak noise from the shock absorber or springs

worn bushings, and attaching components. Repair as
necessary if any of these conditions exist.
The shock absorber bushings do not require any
type of lubrication. Do not lubricate the bushings to
reduce bushing noise. Grease or mineral oil-base lu-
bricants will deteriorate the bushing rubber.The shock absorbers are not refillable or adjust-
