Rear Wheels


The proper alignment of the rear suspension and wheels is essential for proper handling and to providing a reference for front wheel alignment. Always ensure that rear wheel alignment is within specifications prior to checking and adjusting front wheel alignment.

CAMBER

On models with independent rear suspension, rear wheel camber must be within specifications for proper vehicle handling and to prevent uneven tire wear. Rear camber cannot be adjusted. If rear camber is not within specifications, check for damaged or worn suspension components and deformed sheet metal, and repair as needed.



Fig. 1 Measuring Toe-in:





TOE-IN

On models with independent rear suspension, rear toe is the measurement of the rear wheels in relation to the vehicle centerline, Fig. 1. The leading edge of each rear wheel should toe-in slightly toward the vehicle centerline to ensure proper vehicle tracking. Rear toe should be inspected using suitable alignment gauges, following manufacturer's instructions. When checking or adjusting rear toe, always ensure that the amount that the left and right wheels toe-in is as nearly equal as possible.



Fig. 2 Rear Toe-in Adjustment.:





Rear toe-in is adjusted by rotating the cam bolts which secure the rear parallel link to the crossmember.
1. Measure total toe-in and toe-in for each wheel following equipment manufacturer's instructions.
2. Scribe matching mark between cam and parallel link, then loosen nut securing cam bolt.
3. Rotate cam bolt(s) as needed, Fig. 7, to obtain specified toe-in. On graduation on scale varies toe-in approximately .08 inch. Ensure that total toe-in is within specifications and divided equally between left and right wheels.
4. Hold position of cam bolt(s) and torque retaining nuts to 72-87 ft. lbs.
5. Ensure toe-in is still within specifications.
