Alignment: Service and Repair
Front Suspension
Preliminary Checks Prior to Adjustment Front Wheel Alignment
Steering and vibration complaints are not always the result of improper 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 Radial Tire Lead / Pull Description in order to determine if the vehicle has a tire lead problem. Before making any adjustment affecting wheel
alignment, the following checks and inspections should be made to ensure correctness of alignment readings and alignment adjustments:
^
Check all tires for proper inflation pressures and approximately the same tread wear.
^
Check for loose of ball joints. Check tie-rod ends; if excessive looseness is noted, it must be corrected before adjusting.
^
Check for run-out of wheels and tires.
^
Check vehicle trim heights; if out of limits and a correction is to be made, it must be made before adjusting toe.
^
Check for loose of suspension arms.
^
Check for loose or missing stabilizer bar attachments.
^
Consideration must be given to excess loads, such as tool boxes. If this excess load is normally carried in vehicle, it should remain in vehicle
during alignment checks.
^
Consider condition of equipment being used to check alignment and follow manufacturer's instructions.
^
Regardless of equipment used to check alignment, vehicle must be on a level surface both fore and aft and transversely.
NOTE: To prevent possible incorrect reading of camber of caster, vehicle front (or rear) end must be moved up and down a few ties before
inspection.
Front Wheel Alignment Inspection and Adjustment
Toe Inspection and Adjustment
Preparation for toe inspection and adjustment.
^
Place vehicle in non-loaded state on level floor.
^
Set steering wheel in straight state.
^
Check that inflation pressure of each tire is adjusted properly and disc wheel is free from deflection.
^
Check that each suspension part is free from bend, dent, wear or damage in any other form.
^
Check that ground clearance at the right and left is just about the same.
Inspection
Measure toe with toe-in gauge (1).
Toe should be within following specifications.
Toe 0 ± 2 mm (0 ± 0.079 inch)
If toe is out of the value corresponding specification, adjust toe properly.
Adjustment
1) Loosen right and left tie-rod end lock nuts (1) first.
