WHEEL ALIGNMENT (CASTER ANGLE) ADJUSTMENT PROCEDURE
DESCRIPTION
Some 1988-'91 929 and 1989-'92 MPV models may pull to the right or the left. This may be caused by incorrect caster setting or a difference in wheel base dimensions due to improper crossmember installation.* Follow the procedures in this bulletin to correct this problem.
INSPECTION & REPAIR PROCEDURE
NOTE:
Steps 1 and 2 must be performed prior to suspension adjustment.
1. Adjust tire pressure as recommended in the Workshop Manual.
2. Inspect vehicle for damage to suspension and related components.
3. If damage to suspension or components is found, repair and retest for pulling.
4. Rotate the left and right front tires.
5. Align according to the Workshop Manual, Section R.
6. While aligning, if caster angle will not adjust to the proper specification, proceed to step 7. if the proper caster angle is achieved, proceed to step 11*
7. Measure wheelbase side-to-side. Follow steps 8 through 10 until the wheel base dimension is within 1/4" (6.35 mm).*
8. Remove the vehicle's plastic undercover.
9. Loosen the nuts that mount the crossmember to the body.*
NOTE:
When the vehicle pulls to the right side, move the right side of the crossmember forward to increase the right caster angle. At the same time, move the left side of the crossmember backward to decrease the left caster angle. Figure 1.
If the vehicle pulls to the left side, the procedure is opposite of the steps above.
10. Tighten the nuts which mount the crossmember to the body.*
11. Retest vehicle for pulling.
