Calais L4-138 2.3L VIN D FI (1990)
2. Test drive the vehicle.
A. If the vehicle is fixed, OK. Labor operation EO100.
B. If the vehicle torque steers in the opposite direction from the original complaint, the problem is most likely to be tire related. Proceed to step 3.
C. If the vehicle leads/pulls in the same direction, proceed to step 4.
3. Tire/wheel rotation for lead/pull.
A. Swap LF tire/wheel with LR tire/wheel and test drive.
B. If vehicle is fixed, replace LR tire (tire that was originally on RF). If vehicle is not fixed replace RF tire (tire that was originally on LF.)
C. Test drive to confirm fix. Labor operations E0100 and E0421.
4. Wheel alignment. Be sure alignment rack calibration is up to date. Note all before and after readings and record them on the repair order. This
information will be requested if Technical Assistance is contacted, and will be helpful in Engineering analysis.
A. Check camber and reset to nominal specification.
B. Note, do not adjust caster settings. Caster cannot be adjusted. If caster is found to be out of specification, re-check on another machine, and verify
calibration of current machine. If caster is still out of specification, see miscellaneous note # 4. If still out of specification, contact Technical
Assistance so Engineering can be notified see "Miscellaneous Note # 5" before calling Technical Assistance.
5. Test drive vehicle.
A. If vehicle is fixed, OK. Labor operation E2020.
B. If vehicle pulls to left, proceed to step 6.
C. If vehicle pulls to right, proceed to step 7.
6. Reset camber for a lead/pull to the left.
A. Set the RF camber to a "+" value (no more than + 1.00 degree).
B. Set the LF camber to a "-" value (no more than - 1.00 degree).
C. Total cross camber (left minus right) should be no more than 2 degrees.
D. Test drive. If not fixed, contact Technical Assistance.
7. Reset camber for a lead/pull to the right.
A. Set the RF camber to a "-" value (no more than - 1.00 degree).
B. Set the LF camber to a "+" value (no more than + 1.00 degree).
C. Total cross camber (left minus right) should be no more than 2 degrees.
D. Test drive. If not fixed, contact Technical Assistance.
Torque Steer
1. Put vehicle on hoist.
A.
Visually inspect for damaged front and/or rear suspension or steering components.
B.
Check for obvious brake drag.
C.
Swap left front tire/wheel assembly with right front tire/wheel assembly. Cross only the front tires/wheels. Do not perform a standard or
modified "X" rotation.
2. Test drive the vehicle.
A. If the vehicle is fixed, OK.
B. If the vehicle torque steers in the opposite direction from the original complaint, the problem is most likely to be tire related. Proceed to step 3.
C. If the vehicle torque steers in the same direction, proceed to step 4.
3. Tire/wheel rotation for torque steer.
A. Swap LF tire/wheel assembly with LR tire/wheel and test drive.
B. If vehicle is fixed, replace LR tire (tire that was originally on RF). If vehicle is not fixed replace RF tire (tire that was originally on LF.)
C. Test drive to confirm fix. Labor operations E0100 and E0421.
4. Measure front suspension "Z" heights as specified in Service Manual. One method of taking this measurement is to stretch a string tightly between
the grease fittings on the bottom of the ball joints and measure the distance up from the string to the bottom surface of the suspension support. If the
side-to-side difference is greater than 6 mm (1/4 inch), correct the "Z" heights to equal settings. "Z" height can be increased by installing a new
service replacement spring that is one part number "stronger" (or more if required) than the original equiqment spring. Each subsequent spring code
will result in approximately 8 mm (3/8 inch) difference in "Z" height from the previous code.
5. Test drive the vehicle.
A. If the vehicle is fixed, OK Labor operation E3020 or E3021.
B. If the vehicle still torque steers, proceed to next step.
