Preliminary Checks: Notes

Before beginning wheel alignment procedures, ensure following are checked.

• All wheels and tires are of approved size (all 4 identical) and tires are properly inflated. Tread depth has no more than .08" (2 mm) difference between tires on same axle. Correct as necessary.
• Check suspension and suspension components for looseness or damage. Correct as necessary.
• Check wheel bearing play and condition. Correct as necessary.
• Fuel tank full. Spare tire and tools stored in appropriate storage area. Windshield washer reservoir full. Correct as necessary.
• On vehicle equipped with level control (1BG suspension), turn ignition on and allow height control process to run until completed.
• Ensure alignment equipment sliding plates and turn tables are not touching the end stop when checking wheel alignment.
• Alignment is to always include both front and rear axles.
• Check wheels for excessive runout or out-of-balance condition. Balance or repair wheels as necessary. Permissible lateral runout of the wheel rims can already exceed the specified toe-in setting tolerance. If compensation for wheel run-out is not performed, it will not be possible to obtain a correct toe-in adjustment.
• For vehicles with 4-wheel air suspension (1BY), vehicle must be at normal level. Deactivate level control system. See DEACTIVATING/ACTIVATING JACK MODE FOR RIDE HEIGHT SYSTEM (ALLROAD)  . Be sure there is sufficient pressure in pressure reservoir. Check height between center of wheel and bottom edge of fender. Specification is 15.8" +/- .197" (402 mm +/- 5 mm). If this is not the case, basic setting must be performed.
