Preparation for Inspection and Adjustment: Notes

Steering and vibration complaints are not always the result of improper wheel alignment. An additional item to be checked is the possibility of tire lead due to worn or improperly manufactured tires. "Lead" is the vehicle deviation from a straight path on a level road without hand pressure on the steering wheel. Refer to TIRE INSPECTION in order to determine if the vehicle has a tire lead problem. Before inspecting rear wheel alignment and making any adjustment affecting wheel alignment, perform the following checks, inspections and repair/replacement to ensure correct measurements and adjustments.

• Check all tires for proper inflation pressure. Adjust pressure for any improperly inflated tire(s).
• Check that all tires are of the same type and brand and also they have approximately the same tread wear. Replace all tires with new ones if necessary.
• Check rear wheel bearings for damage. Replace damaged bearing(s) with new one(s).
• Check wheels and tires for deformation. Repair or replace them if necessary, see WHEEL INSPECTION .
• Check that rear suspension system is properly installed and free of damage, see REAR SUSPENSION ASSEMBLY INSPECTION .
• Check suspension components for bends, dents, wear or other damage.
• Place vehicle on level surface in unloaded state.
• Push vehicle body to bounce vehicle up and down several times to stabilize rear suspension.
• Check that ground clearance on one side is approximately the same as that on the other side.
