Front Camber Adjustment

IMPORTANT: Rear wheel alignment angles must be set to correct specifications before front wheel alignment angles are adjusted.

Lock the steering wheel in the straight ahead position.
Loosen the 2 strut-to-knuckle fasteners and pull or push the knuckle in the direction of the desired change. This will allow up to 1.5 degrees of adjustment.
NOTE: If more than 1.5 degrees of camber adjustment is required, check for bent suspension components or body structure.
If more than 1.5 degrees of camber adjustment is required and no bent components are observed:

CAUTION: Ensure that the vehicle is properly supported and squarely positioned. To help avoid personal injury when a vehicle is on a hoist, provide additional support for the vehicle on the opposite end from which the components are being removed.
1. Raise the vehicle on the hoist.
2. Remove the wheel and tire assembly.
3. Remove the 2 strut-to-knuckle fasteners and separate the knuckle from the strut bracket.

  IMPORTANT: The strut mounting bracket consists of 2 layers of metal, an inner layer and an outer layer. The inner layer has a round 14.4-14.8 mm (0.57-0.58 in) hole through it at the mounting locations, while the outer layer has a 18.4-18.8 mm (0.72-0.74 in) slot through it.
4. Using a round file or grinder, remove material from the inner layer of the strut bracket lower hole. The round hole may be increased to the size and shape of the slot in the outer layer. Do this on both sides of the strut bracket.
  - To increase negative camber, remove material from the outside of the lower strut hole.
  - To decrease negative camber, remove material from the inside of the lower strut hole.
  NOTE: Refer to FASTENER NOTICE .
  
  IMPORTANT: If the strut was filed or ground, paint the exposed metal with primer.
5. Position the knuckle back into the strut with fasteners.
Tighten the strut-to-knuckle fasteners.
Tighten: Tighten the front strut-to-steering knuckle fasteners to 170 N.m (126 lb ft).

NOTE: Before installing wheels, remove rust or corrosion from wheel mounting surfaces and brake rotors/drums. Failure to do so can cause wheel nuts to loosen in service.
Position the wheel onto the hub.
Install the wheel nuts and tighten the wheel nuts in a crisscross pattern. Repeat the tightening pattern to ensure the torque is correct.
Tighten: Tighten the wheel nuts to 140 N.m (103 lbs ft).
Lower the vehicle from the hoist.
Inspect the camber angle and adjust if necessary.
