Riding Height: Adjustment
WARNING: This page does not describe the selected car, but rather 17 other vehicles, including the 1991 Pontiac Sunbird, 1991 Pontiac Grand Prix, 1991 Pontiac Grand Am, 1991 Pontiac Firebird, and 1991 Pontiac Bonneville. However, it is still accessible from the selected car via links, so may be relevant.
NOTE:
On vehicles with electronic chassis controls, ensure all systems are functional before adjusting riding height or wheel alignment.
Before adjusting alignment, check riding height. Riding height must be checked with vehicle on level floor and tires properly inflated. Tire inflation specifications can be found on door pillar, side wall of tire, sun visor or glove box. Bounce vehicle several times and allow suspension to settle.
Visually inspect vehicle for signs of abnormal height from front to rear or side to side. Remove extra heavy items from passenger and luggage compartments. If riding height is not within specifications, check, repair or replace suspension components. See RIDING HEIGHT SPECIFICATIONS table. See Figure .
