Preliminary Checks

Before adjusting wheel alignment, check following:

• Do not check vehicle alignment before vehicle has completed 600 to 1200 miles, to allow for coils springs to settle.
• The actual load condition at the time of alignment is a deciding factor for the application of the specified values (empty, 1/2 net load, full load).
• Ensure tires are of same construction and tread style, equal in tread wear and overall diameter. Verify that radial and axial runout is not excessive. Tire inflation should be adjusted to manufacturer's specifications.
• Steering linkage and suspension must not have excessive play. Check for wear in tie rod ends and ball joints. Springs must not be sagging. Control arm and strut rod bushings must not have excessive play.
• Vehicle must be on level floor and spare tire in place.
• Bounce front and rear end of vehicle several times. Confirm vehicle is at normal ride height.
• Steering wheel must be centered with wheels in straight ahead position. If required, shorten one tie rod adjusting sleeve and lengthen opposite sleeve (equal amount of turns).
• Wheel bearings should have the correct preload and lug nuts must be tightened to manufacturer's specifications.
• Ensure that sliding plates and turntables (alignment equipment) are not touching an end stop when checking wheel alignment. Test equipment must be properly adjusted and attached to the vehicle; observe device manufacturer's operating instructions.
