Adjustment Bolt Package Installation - Rear-Wheel-Drive (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.

Raise the vehicle by the frame until the tires are not supporting the weight of the vehicle.
Remove the belly pan as necessary. Refer to REMOVAL .
Lower control arm bolt only:
- Remove the screws fastening the heat shields covering the stabilizer bar bushing retainers to the cradle. Remove the heat shields.
- Remove the four bolts (two each) fastening the stabilizer bar bushing retainers to the cradle.
- Swing the stabilizer bar rearward and down out of the way of the control arm mounting bolts.

CAUTION: Wheel alignment adjustment bolts have offset grooves cut into the length of the bolt (2). If removing or installing lower control arm or tension 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.
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.

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" (c).
Camber Adjustment - The adjustment bolts are designed to work in conjunction with "bat wing" holes that are formed into the inner metal of the lower control arm bushing (1) allowing for lower control arm movement approximately 0.3° in either direction.
1. To achieve more positive camber, refer to (a) in the figure. Move the control arm or tension strut in the desired direction, then insert the adjustment bolt (2) with a washer installed through the round hole in the engine cradle and bat wing hole (1) in the bushing inner metal.
2. To achieve more negative camber, refer to (b) in the figure. Move the control arm or tension strut in the desired direction, then insert the adjustment bolt (2) with a washer installed through the round hole in the engine cradle and bat wing hole (1) in the bushing inner metal.

NOTE: The original (non-grooved) mounting bolt (3) lies through the center of the hole (1), between the "bat wings" (c).
Caster Adjustment - The adjustment bolts are designed to work in conjunction with "bat wings" that are formed into the engine cradle (1) allowing for tension strut movement approximately 0.3° in either direction.
1. To achieve more positive caster, refer to (a) in the figure. Move the tension strut 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.
2. To achieve more negative caster, refer to (b) in the figure. Move the tension strut 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.
Start a NEW nut and a washer (on RWD vehicles) 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.
Lower the vehicle to curb position. Jounce the rear, then the front of the vehicle an equal amount of times.
Using a crowfoot wrench, tighten the adjustment bolt nut to 176 N.m (130 ft. lbs.) while holding the bolt stationary.
Lower control arm adjustment bolt only - Reinstall the stabilizer bar and heat shields.
Measure camber and caster. If camber and caster are not within specifications, inspect the suspension components 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.
Install the belly pan. Refer to INSTALLATION .
