B2300 SE Regular Cab 2WD L4-2.3L VIN A (1997)
Alignment: Service and Repair
Lean Adjustments
NOTE: Changing front ride height by adding the service shim also affects caster angles and camber angles. Adding the 4.5 mm (0.18 inch) thick shim
may reduce caster by up to 0.40 degrees on the side the shim is added and also increase camber by 0.15 degrees.
FRONT LEAN
1. Measure the left and right front ride heights. Add 8 mm (0.3125 inch) to the right side ride height measurement.
2. If the difference between left and right ride heights exceeds 16 mm (5/8 inch) and is less than 20 mm (3/4 inch), measured at the wheel house
opening to ground, add one shim to the side of the vehicle that is low.
NOTE: The shim is to be placed under the lower spring seat.
3. If there is a computed side-to-side difference of 20 mm (3/4 inch) or more in the left/right wheel house openings, swap springs from side-to-side.
NOTE: If the lean condition follows the spring (lean now on other side of the vehicle), one or both springs are out of specification. Replace both
springs with new ones. If lean condition remains unchanged, something other than a bad spring is the cause and must be diagnosed.
NOTE:
^
A side-to-side lean at the rear of the vehicle can be adjusted by approximately 6 mm (1/4 inch) by installing a shim between the rear spring and
axle on the low side of the vehicle.
^
A "low at the rear" vehicle can be raised approximately 6mm (1/4 inch) by installation of one shim on each side.
