Technical Service Bulletin
Technical Background
At temperatures below 32 °F, frozen water/dirt above the shock absorber mountings causes restrictions to the
operation of the shock absorber mounting.
Note:
• The concern described depends on the temperature, as it is caused by ice or frozen dirt above the shock
absorber mounting.
• A simple check to verify the customer’s concern can be done by carefully heating up the shock absorber
mounting and reevaluating the vehicle.
Production Solution
Not applicable.
