WHEEL ALIGNMENT SPECIFICATIONS & PROCEDURES
1998 Mitsubishi Montero
1997-98 WHEEL ALIGNMENT
Mitsubishi - Specifications & Procedures
Diamante, Eclipse, Galant, Mirage,
Montero, Montero Sport, 3000GT
RIDING HEIGHT ADJUSTMENT
NOTE: Prior to performing wheel alignment, perform preliminary
visual and mechanical inspection of wheels, tires and
suspension components. See PRE-ALIGNMENT INSTRUCTIONS in
WHEEL ALIGNMENT THEORY & OPERATION article in GENERAL
INFORMATION.
NOTE: On vehicles with electronic chassis controls, ensure all
systems are functional before attempting to adjust riding
height or wheel alignment. See appropriate ELECTRONIC
article under SUSPENSION.
1) Before adjusting wheel alignment, visually inspect
vehicle. Remove any heavy items from passenger and luggage
compartments. Ensure tires are properly inflated and vehicle is level.
Bounce vehicle several times, and allow suspension to settle.
2) Check riding height from front to rear and from side to
side. If riding height is not as specified on Montero and Montero
Sport, adjust torsion bar anchor arm nut until correct height is
obtained. See RIDING HEIGHT SPECIFICATIONS (FRONT) table. On all other
models, riding height for left and right sides of vehicle should not
vary more than 1.0" (25.4 mm). If riding height is not within
specification, check and repair suspension before adjusting alignment.
RIDING HEIGHT SPECIFICATIONS (FRONT)
