DRIVE AXLE - NOISE DIAGNOSIS
Unrelated Noises
Some driveline trouble symptoms are also common to the
engine, transmission, wheel bearings, tires, and other parts of the
vehicle. Ensure cause of trouble actually is in the drive axle before
adjusting, repairing, or replacing any of its parts.
Non-Drive Axle Noises
A few conditions can sound just like drive axle noise and
have to be considered in pre-diagnosis. The 4 most common noises are
exhaust, tires, CV/universal joints and wheel trim rings.

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.

GENERAL INFORMATION
Wheel Alignment Theory & Operation
ALL MODELS
* PLEASE READ THIS FIRST *
NOTE: This article is intended for general information purposes
only. This information may not apply to all makes and models.
PRE-ALIGNMENT INSTRUCTIONS
GENERAL ALIGNMENT CHECKS
Before adjusting wheel alignment, check the following:
* Each axle uses tires of same construction and tread style,
equal in tread wear and overall diameter. Verify that radial
and axial runout is not excessive. Inflation should be at
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. See Fig. 1.
Fig. 1: Checking Steering Linkage
* Vehicle must be on level floor with full fuel tank, no
passenger load, spare tire in place and no load in trunk.
Bounce front and rear end of vehicle several times. Confirm
