Vehicle Involved: Trucks with solid front axles and lifted vehicles with leaf springs.
Condition: Steering wandering or pulling to one side. Excessive u-joint wear and vibration.
Repair Procedure: Caster wedges are used to maintain factory caster specs on vehicles with solid axles and leaf springs. If caster is not in specs, vehicle may wander or pull to one side.
The wedges come in different alloys to match the application and are stepped at ½ degree increments. Various widths are also available to match leaf springs.
These same wedges can be used on the front or rear of a lifted vehicle to maintain proper driveshaft angles. Example: pick-up truck lifted using blocks between axle and spring. Now the transfer case is 4 inches higher than differential. To reduce angle, use wedges to tilt differential up. Be aware that too much angle will keep pinion bearing from proper lubrication. Installation should be done by a qualified technician. Use caution when installing parts and torque all bolts to specifications.
Wedge types and applications can be found in the Alignment Product Catalog under Truck Alignment Solutions.
