WHEEL ALIGNMENT
DESCRIPTION - WHEEL ALIGNMENT
Vehicle wheel alignment is the positioning of all
interrelated front and rear suspension angles. These
angles affect the handling and steering of the vehicle
when it is in motion. Proper wheel alignment is
essential for efficient steering, good directional stabil-
ity, and proper tire wear.
The method of checking a vehicle's front and rear
wheel alignment varies depending on the manufacturer
and type of equipment used. The manufacturer's
instructions should always be followed to ensure accu-
racy of the alignment, except when DaimlerChrysler
Corporation's wheel alignment specifications differ.
On this vehicle, the suspension angles that can be
adjusted are as follows:
Front
• Camber
• Toe
Rear
• Toe
Check the wheel alignment and make all wheel align-
ment adjustments with the vehicle standing at its
proper curb height specification. Curb height is the nor-
mal riding height of the vehicle. It is measured from a
certain point on the vehicle to the ground or a desig-
nated area while the vehicle is sitting on a flat, level
surface. Refer to Curb Height Measurement in this sec-
tion for additional information.
Typical wheel alignment angles and measurements
are described in the following paragraphs.
CAMBER
Camber is the inward or outward tilt of the top of
the tire and wheel assembly (Fig. 1). Camber is mea-
sured in degrees of angle relative to a true vertical
line. Camber is a tire wearing angle.
