alignment before installing an adjustment bolt package. If an adjustment bolt package installation is necessary,
inspect the suspension components for any signs of damage or bending first.

CAUTION: Do not attempt to adjust the vehicles wheel alignment by heating, bending or by performing any
other modification to the vehicle’s front suspension components or body.

ADJUSTMENT BY SHIFTING CRADLE

CAUTION: Always use care when shifting cradle to avoid damaging other components on the vehicle.

1. Loosen the four bolts (1) fastening the engine cra-

dle (2) to the frame just enough to allow movement
of the cradle.

2. Shift cradle as necessary to bring camber or caster

into specifications. When shifting cradle, use care
not to move other angles (camber or caster) that
are within specifications, out of specifications.

3. Tighten the four bolts (1) fastening the engine cra-

dle (2) to the frame to specifications.

4. Jounce the rear, then front of the vehicle an equal

amount of times.

5. Measure camber and caster. If camber and caster

are within specifications, proceed to TOE. If cam-
ber or caster cannot be brought into specifications,
perform

the

BOLT

PACKAGE

INSTALLATION below.

ADJUSTMENT BOLT PACKAGE INSTALLATION - AWD

NOTE: Adjustment bolts for AWD and RWD are not
interchangeable.

The adjustment bolt package contains 2 special bolts
(1). These bolts can be identified by the offset grooves
cut into the thread section (2). These bolts are
designed to replace the inboard mounting bolts of the
lower control arm at the engine cradle. Each bolt
allows approximately 0.3 degrees of movement. To
adjust camber only, use both bolts, one at each leg of
the control arm. To adjust caster only, use one bolt at
the front leg only.

1. Raise the vehicle by the frame until the tires are not supporting the weight of the vehicle.

2. Remove the belly pan as necessary. (Refer to 23 - BODY/EXTERIOR/BELLY PAN - REMOVAL)

3. Lower control arm rear bolt only:

a. Remove the screws fastening the heat shields covering the steering gear inner tie rod boots. Remove the

heat shields.

b. Loosen (do not remove) the steering gear mounting bolt furthest from the side of adjustment bolt installation.

c. Remove the two remaining steering gear mounting bolts and allow steering gear to relax on the side of

adjustment bolt installation, giving access to the lower control arm rear mounting bolt.

WHEEL ALIGNMENT

CAUTION: Wheel alignment adjustment bolts have
offset grooves cut into the length of the bolt (2). If
removing or installing lower control arm or ten-
sion strut mounting bolts that have these grooves,
DO NOT ROTATE THE BOLT. To remove the bolt,
hold the bolt head stationary and rotate the nut,
then slide the bolt straight out of the bushing.
This is necessary to avoid damaging the bat wings
in the bushing inner metal or cradle.

4. Hold the head of the control arm or tension strut mounting bolt stationary and remove the nut. Slide the bolt

straight out of the bushing and discard.

CAUTION: When installing an adjustment bolt, be sure to install it in the correct direction. Lower control
arm rear mounting bolts must be installed from the rear-forward and lower control arm front mounting bolts
must be installed from the front-rearward.

NOTE: The grooves on the adjustment bolts are off-center forcing the bolt to be installed in one of two
ways depending on whether more positive or negative camber or caster is necessary. The Bolts must be
rotated 180° to achieve either more positive or negative camber or caster. DO NOT force the adjustment
bolt.

NOTE: The original (non-grooved) mounting bolt
(3) lies through the center of the hole (1), between
the “bat wings” as shown in (c).

5. Camber Adjustment – The adjustment bolts are

designed to work in conjunction with “bat wing”
holes that are formed into the engine cradle (1)
allowing for lower control arm movement approxi-
mately 0.3° in either direction.

•

To achieve more positive camber, refer to (a) in
the figure. Move the control arm in the desired
direction, then insert the adjustment bolt (2) with
a washer installed through the bat wing hole in
the engine cradle (1) and round hole in the bush-
ing inner metal.

•

To achieve more negative camber, refer to (b) in
the figure. Move the control arm in the desired
direction, then insert the adjustment bolt (2) with
a washer installed through the bat wing hole in
the engine cradle (1) and round hole in the bush-
ing inner metal.

NOTE: The original (non-grooved) mounting bolt
(3) lies through the center of the hole (1), between
the “bat wings” as shown in (c).

6. Caster Adjustment – The adjustment bolts are

designed to work in conjunction with “bat wings”
that are formed into the engine cradle (1) allowing
for lower control arm movement approximately 0.3°
in either direction.

•

To achieve more positive caster, refer to (a) in
the figure. Move the lower control arm in the
desired direction, then insert the adjustment bolt
(2) with a washer installed through the bat wing
hole in the engine cradle (1) and the round hole
in the bushing inner metal.

•

To achieve more negative caster, refer to (b) in
the figure. Move the lower control arm in the
desired direction, then insert the adjustment bolt
(2) with a washer installed through the bat wing
hole in engine cradle (1) and round hole in the
bushing inner metal.

7. Start a NEW nut on the end of the mounting bolt by hand, then while holding the head of the bolt stationary,

install the nut. Do not tighten the nut at this time.

8. Rear adjustment bolt only – Reinstall the steering gear and heat shields. (Refer to 19 - STEERING/GEAR -

INSTALLATION)

9. Lower the vehicle to curb position. Jounce the rear, then the front of the vehicle an equal amount of times.

10. Using a crowfoot wrench, tighten the adjustment bolt nut to 176 N·m (130 ft. lbs.) torque while holding the bolt

stationary. A socket on the end of a breaker bar works well for holding the rear bolt stationary with the steering
gear is installed.

11. Measure camber and caster. If camber and caster are not within specifications, inspect the suspension compo-

nents for any signs of damage or bending. If camber and caster (and cross-camber and cross-caster) are within
specifications, proceed with TOE to check and adjust toe.

12. Install the belly pan. (Refer to 23 - BODY/EXTERIOR/BELLY PAN - INSTALLATION)

ADJUSTMENT BOLT PACKAGE INSTALLATION - RWD

NOTE: Adjustment bolts for AWD and RWD are not
interchangeable.

The adjustment bolt package contains 2 special bolts
(1). These bolts can be identified by the offset grooves
cut into the thread section (2). These bolts are
designed to replace the inboard mounting bolts of the
lower control arm and tension strut. Each bolt allows
approximately 0.3 degrees of movement. To adjust
camber only, use both bolts, one at the tension strut
and the other at the lower control arm. To adjust
caster only, use one bolt at the tension strut only.

1. Raise the vehicle by the frame until the tires are not supporting the weight of the vehicle.

2. Remove the belly pan as necessary. (Refer to 23 - BODY/EXTERIOR/BELLY PAN - REMOVAL)

3. Lower control arm bolt only:

a. Remove the screws fastening the heat shields covering the stabilizer bar bushing retainers to the cradle.

Remove the heat shields.

b. Remove the four bolts (two each) fastening the stabilizer bar bushing retainers to the cradle.

c. Swing the stabilizer bar rearward and down out of the way of the control arm mounting bolts.

4. Hold the head of the control arm or tension strut mounting bolt stationary and remove the nut. Slide the bolt

straight out of the bushing and discard.

CAUTION: When installing an adjustment bolt, be sure to install it in the correct direction. Lower control
arm bolts must be installed from the rear-forward to avoid contact with the stabilizer bar upon installation.
Tension strut bolts must be installed from the front-rearward.
