Rear Lean
Verify Automatic Ride Control (ARC) is working properly. Also put vehicle in 2-wheel drive and shut service switch OFF.With the underslung rear suspension, use of shims will not have any effect on a lean condition. Use the following procedure to verify and correct a rear lean condition.
1. Measure rear ride height by measuring the height of the right and left rear fender lip openings.
2. Compute the difference.
3. Inspect the vehicle for any excess loads which might weigh the vehicle down on one side more than the other. Usually a weight of at least 50 pounds is required to cause such a lean.
4. If lean condition is not caused by weight, swap the rear springs from side-to-side.
5. If the lean changes sides, the lean condition is most likely caused by a bad spring. Replace both springs.
6. If the lean condition did not change when the springs were changed, factors other than suspension are the cause.
