1988 Wheel Alignment
INTRODUCTION
PRE-ALIGNMENT
VEHICLE CHECKS
Prior to making wheel alignment adjustments, check and
adjust the following items:
1) Tire pressure must be inflated to manufacturers
recommended specifications.Tires should be equal in size and type.
Runout must not be excessive. Tires and wheels should be in balance.
2) Wheel bearings must be properly adjusted. Steering
linkage and suspension must not have excessive wear and/or looseness.
Check for wear in tie rod ends and ball joints.
3) Steering gear box must not have excessive play. Check and
adjust to manufacturer's specifications.
4) Vehicle must be at correct ride height with full fuel
load and spare tire in vehicle. No extra load should be on vehicle.
5) Vehicle must be level with floor and with suspension
settled. Jounce front and rear of vehicle several times and allow it
to settle to normal ride height.
6) Ensure steering wheel spokes are centered with front
wheels in straight-ahead position, correct by shortening one tie rod
adjusting sleeve and lengthening opposite sleeve equal amounts.
7) Ensure wheel lug nuts are tightened to torque
specifications.
DESCRIPTION
CAMBER
Camber is the inward or outward tilt of the wheel as viewed
from front of vehicle. Camber is measured from centerline of vehicle.
When wheel is tilted outward at top from centerline of vehicle,
camber is positive. When wheel is tilted inward at top from
centerline of vehicle, camber is negative. Camber is measured in
degrees from vertical.

CASTER
Caster is the tilting of front steering axis. This forward

RIDING HEIGHT SPECIFICATIONS
Inflate tires to proper air pressure. Specifications can be
found on door pillar or in glove box. Cargo compartment must by
empty. Fuel tank should be full. Bounce vehicle up and down to
normalize ride height. Ride height specifications in regard to setting
camber and caster are not provided by the manufacturer.

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
