STANDARD PROCEDURE - WHEEL ALIGNMENTPRE-WHEEL ALIGNMENT VEHICLE INSPECTION
CAUTION: If during the inspection the front suspension crossmember shows any sign of impact damage, the steering column lower coupling must be inspected.
Before any attempt is made to change or correct the wheel alignment, the following inspection and necessary corrections must be made to the vehicle to ensure proper alignment.
1. Be sure the fuel tank is full of fuel. If the fuel tank is not full, the reduction in weight will affect the curb height of the vehicle and the alignment specifications.
2. The passenger and luggage compartments of the vehicle should be free of any load that is not factory equipment.
3. Check the tires on the vehicle. The tires are to be inflated to the recommended air pressure. All tires must be the same size and in good condition with approximately the same tread wear.
4. Check the front tire and wheel assemblies for excessive radial runout.
5. Inspect all suspension component fasteners for looseness and torque.
6. Inspect the lower front ball joints and all steering linkage for looseness and any sign of wear or damage.
7. Inspect the rubber bushings on all the suspension components for signs of wear or deterioration. If any bushings show signs of wear or deterioration, they should be replaced prior to aligning the vehicle.
WHEEL ALIGNMENT SETUP
1. Position the vehicle on an alignment rack.
2. Install all required alignment equipment on the vehicle, per the alignment equipment manufacturer's instructions. On this vehicle, a four-wheel alignment is recommended.
NOTE: Prior to reading the vehicle's alignment readouts, the front and rear of vehicle should be jounced. Induce jounce (rear first, then front) by grasping the center of the bumper and jouncing each end of vehicle an equal number of times. The bumper should always be released when vehicle is at the bottom of the jounce cycle.
3. Read the vehicle's current front and rear alignment settings. Compare the vehicle's current alignment settings to the vehicle specifications for camber, caster and toe-in.
4. If the rear alignment is out of specification, adjust it first before proceeding to the front.
CAMBER AND CASTER
Front and rear camber and caster settings on this vehicle are determined at the time the vehicle is designed, by the location of the vehicle's suspension components. This is referred to as Net Build. The result is no required adjustment of camber and caster after the vehicle is built or when servicing the suspension components. Thus, when performing a wheel alignment, caster and camber are not normally considered adjustable angles. Camber and caster should be checked to ensure they meet vehicle specifications.
If either front or rear camber is found not to meet alignment specifications, it can be adjusted using an available camber adjustment bolt package. Before installing a camber adjustment bolt package on a vehicle found to be outside the specifications, inspect the suspension components for any signs of damage or bending.
No adjustment can be made to the caster setting on this vehicle. If the vehicle's caster is not within alignment specifications, check for damaged suspension components or body parts.
CAUTION: Do not attempt to adjust the vehicles wheel alignment by heating or bending any of the suspension components.
CAMBER ADJUSTMENT BOLT PACKAGE INSTALLATION
The camber adjustment bolt package contains new bolts and nuts for attaching the strut clevis bracket to the steering knuckle. The bolts contained in the package are slightly undersize allowing for movement between the strut clevis bracket and the steering knuckle. The movement allowed by the undersize bolts provides approximately one degree of camber adjustment per side of the vehicle. To install and adjust the camber adjustment bolt package, follow the procedure.
CAUTION: There are separate camber adjustment bolt packages for the front and rear of the vehicle. Be sure to use the correct package.
1. Raise the vehicle until its tires are not supporting the weight of the vehicle.
CAUTION: The knuckle to strut assembly attaching bolt shanks are serrated and must not be turned during removal. Remove the nuts while holding the bolts stationary.
2. Remove the wheel and tire assembly at the strut requiring modification.
3. Remove the original upper bolt attaching the strut clevis bracket to the knuckle (Fig. 7) (Fig. 8).
4. Install a bolt from the adjustment package into the hole where the original bolt was removed. Install the bolt from the rear.
5. Install a nut provided in adjustment package on the replacement bolt. Tighten the nut until it's snug, but still allowing the knuckle to slide in the clevis bracket.
6. Remove the original lower bolt.
7. Install a bolt from the adjustment package into the bottom hole of the strut clevis bracket. Install the bolt from the rear.
8. Install a nut provided in adjustment package on the replacement bolt. Tighten the nut until it's snug.
9. Reinstall the tire and wheel assembly
10. Perform the above procedure to any of the remaining struts as required.
11. Lower the vehicle and jounce the front and rear of the vehicle.
12. Adjust the front or rear camber to the preferred setting by pushing or pulling on the top of the tire. When camber is set to specifications, tighten the upper and lower strut clevis bracket bolts. Again jounce the front and rear of the vehicle, then verify the camber settings.
13. Torque front strut clevis bracket-to-steering knuckle attaching bolts to 53 Nm (40 ft. lbs.), plus an additional 1/4 turn after the torque is met. Torque the rear strut clevis bracket-to-rear knuckle attaching bolts to 95 Nm (70 ft. lbs.).
14. Once camber is within specifications, adjust toe to meet the preferred specification setting. Refer to TOE within this wheel alignment service procedure.
TOE
1. Center the steering wheel and lock it in place using a steering wheel clamp.
NOTE: When performing the toe setting procedure, make sure the rear toe is set to the preferred specification before setting the front toe to the preferred specification.
REAR TOE
1. Loosen the nuts on the left and right rear lateral link attaching bolts at the rear crossmember as necessary to allow rotation of the rear toe adjustment cams (Fig. 9).
CAUTION: When adjusting rear toe, the notches on the toe adjustment cams are not to be facing down. The notches in the adjustment cams are only to be facing up or toward one side.
2. Rotate each toe adjustment cam until the preferred rear toe specification is obtained (Fig. 9). Refer to WHEEL ALIGNMENT SPECIFICATIONS.
3. While holding the toe adjustment cams from turning, tighten the attaching bolt nuts. This will securely hold the adjustment cams in position. Tighten the attaching bolt nuts to a torque of 88 Nm (65 ft. lbs.).
4. Proceed to FRONT TOE to set the front toe.
FRONT TOE
CAUTION: Do not twist the inner tie rod-to-steering gear rubber boots while turning the inner tie rod during the front toe adjustment.
1. Loosen the tie rod adjusting jam nuts (Fig. 10). Grasp each inner tie rod at its hex and rotate it one way or the other until the front wheel toe is set to the preferred specification. Refer to WHEEL ALIGNMENT SPECIFICATIONS.
2. Tighten tie rod adjusting jam nuts to a torque of 75 Nm (55 ft. lbs.).
3. Make sure the inner tie rod-to-steering gear rubber boots are not twisted. If twisted, loosen the boot clamp at the inner tie rod and move the boot as necessary.
4. Remove steering wheel clamp.
5. Remove the alignment equipment.
6. Road test the vehicle to verify the steering wheel is straight and the vehicle does not pull or wander.
