HERE IS THE PROCEDURE FOR CHECKING AND CORRECTION OF SIDE TO SIDE LEAN HOPE THIS ANSWERS YOUR QUESTION AND HELPS TO SOLVE YOUR PROBLEM
Lean Correction — Rear<O
</O
NOTE: When verifying the vehicle lean, all tires must be inflated to the proper specifications and all equipment must be removed from the vehicle, such as tool boxes, caps, bed fuel tanks, etc. The vehicle must also be parked on a level surface.<O
</O
Inspect all four tires for proper inflation, adjust as necessary. Refer to the Safety Certification sticker located on driver door jamb.<O
</O
NOTE: The front and rear springs must be in proper working order before a vehicle lean condition can be properly diagnosed.<O
</O
Inspect the front and rear springs for any signs of damage (i.e. fractured or broken), replace as necessary. If a spring is damaged, replace the spring and re-evaluate the vehicle.<O
</O
If the lean condition is corrected, no further action is necessary.If the lean condition is not corrected, proceed to next Step<O
</O
With the vehicle on a level surface and the suspension at curb height, measure the vehicle ride height from the bottom wheel lip (where the wheel and tire meet) to the top of the wheel well opening at all four corners. Record the measured values.
NOTE: MEASURE AT THE SAME POINT FROM SIDE TO SIDE
For the front measurements, take the smaller measured value and subtract it from the larger measured value, this is the wheel well difference number. Record this number. <O
</O
Repeat the calculation using the rear measurements.<O
</O
Measure chassis ride height and record the measured values. For the front chassis ride height measure between the spring seat and the bottom of the frame rail and for rear chassis ride height measure from the top of the axle to the bottom of the frame rail.
NOTE: MAKE SURE THAT YOU MEASURE IN THE SAME SPOT SIDE TO SIDE <O
</O
For the front measurements, take the smaller measured value and subtract it from the larger measured value, this is the chassis ride height difference number. Record this number. <O
</O
Repeat the calculation using the rear measurements.<O
</O
Using the recorded wheel well difference numbers, the recorded chassis ride height difference numbers and then follow the corrective action, determine what repair action is needed to correct the vehicle lean condition.
CORRECTIVE ACTION IS AS FOLLOWS:
if wheel lip to wheel well differential L-R is 0-3/4" & chassis ride height differential L-R is < 0-3/4" action to take is none.
if wheel lip to wheel well differential L-R is >3/4" & chassis ride height differential L-R is <0-3/4" action to take is check frame and body system. no chassis adjustment
if wheel lip to wheel well differential L-R is >3/4" & chassis ride height differential L-R is 3/4"-1" action to take is install shim 3CAZ-5A300-AA on low side of truck
if wheel lip to wheel well differential L-R is >3/4" & chassis ride height differential L-R is 1"to 1-3/4" action to take is install shim 5C3Z-5742-AA on low side of truck
if wheel lip to wheel well differential L-R is >3/4" & chassis ride height differential L-R is 2" & greater action to take is replace spring
JACK UP TRUCK AND INSTALL JACK STANDS ON THE FRAME
<O
</O
SUPPORT THE AXEL USING A SUITABLE JACK<O
</O
Remove and discard the four U-bolts nuts and the two U-bolts to allow the rear axle to separate from the rear spring.<O
</O
Turn the shim so the recess is facing upward.<O
</O
Insert the shim between the rear spring and the spring seat.
Position the shim so the tie bolt through the spring leaves is in the shim recess, the stud on the bottom of the shim is in the spring seat recess, and the shim is aligned with the rear spring.
Install two new U-bolts and four new nuts.
Measure chassis ride height.
Replace the spring if the ride height is now greater than 200 mm for a single rear wheel vehicle or 210 mm for a dual rear wheel vehicle.
NOTE: Front side lean can be adjusted approximately 10 mm (3/8 in.) by installing shim D7TZ-5742-A on the low side. A vehicle that is low at the front can be raised by installing shims at both sides. HOPE THIS HELPS!!
