Rear Alignment Procedure
NOTICE:Since rear camber will now be adjustable, and toe and camber setting impact each other, the following order of adjustment must be followed.
1. Rear camber initial set
2. Rear toe initial set
3. Rear camber final set
4. Rear toe final set
5. Right front camber
6. Left front camber
7. Front toe
IMPORTANT:
When measuring alignment angles, it is critical that the vehicle bumper height be correct. Measure and adjust bumper height according to the following procedure before performing alignment.
1. Place vehicle on a level surface.
2. Adjust tire pressure to correct specifications.
Curb bumper height should be measured with:
^ 207 kPa (30 psi) tire pressure front tires
^ 207 kPa (30 psi) tire pressure rear tires
3. If vehicle fuel tank is not full, the chart shown may be used to determine amount of weight necessary to be added to the trunk of vehicle to simulate a full fuel tank.
4. Bounce front and rear of vehicle a few times to settle suspension.
5. Measure front and rear vehicle curb trim height.
6. After taking the initial rear camber reading, the rear of the vehicle.
7. Loosen the rear lower control arm to knuckle bolt and move the knuckle in for more positive (+) or out for more negative Camber. It may be helpful to scribe around the bolt head as a reference before making adjustments.
8. Tighten the rear lower control arm to knuckle bolt but do not torque at this time.
9. Lower and jounce vehicle, then re-check Camber.
10. Repeat steps 1 through 4 until camber is within 0.25 degrees of desired setting.
11. Remove rear axle control arm bolts and cage nuts and discard.
NOTICE:
Use new bolts and cage nuts. Torque retention of old bolts and nuts may not be sufficient.
IMPORTANT:
Do not tighten bolts at this time.
12. Install new bolts leaving the inside forward bolt out.
13. Install Rear Toe Adjusting Tool KM-900, into the open bolt hole.
14. Using Rear Toe Adjusting Tool KM-900, move rear axle control arm in the direction of necessary toe correction.
15. Snug rear axle control arm bolts, do not tighten to final torque at this time.
16. Recheck toe and adjust if necessary.
17. When Rear Toe settings are within 0.10° of desired final settings continue with next step.
18. Recheck and, if necessary, adjust camber using steps 1 through 4 above.
19. When Camber has reached desired setting, torque rear suspension lower control arm-to-knuckle bolt using the torque angle method and Torque Angle Gauge SA9140E (or equivalent).
Torque:
Rear Suspension Control Arm-to-Knuckle
Bolt: 90 N.m (66 ft-lbs) + 60° to 75°
20. Recheck toe and adjust if necessary.
21. Using Torque Angle Gauge (or equivalent), tighten rear axle control bolts using the torque angle method.
Torque:
Rear Axle Control Arm Bracket-to-Body
Bolts: 90 N.m (66 ft-lbs) + 30° to 45°
22. Repeat procedure for other rear wheel.
23. Check front wheel alignment and adjust if necessary using the appropriate section of the applicable model year L-Series Chassis Service Manual.
24. After alignment is completed print out or record final "Alignment Specifications" (alignment performed).
