Front Lean

Measure the left and right front ride heights as shown in the illustration.

NOTE: Add 6 mm (1/4 inch) to the right side ride height measurement.





Compute the difference between left and right ride heights as shown with the examples. If the difference exceeds 3-9 mm (1/8-3/8 inch) and is LESS than 19 mm (3/4 inch), measured at the wheel house opening to ground, add one shim to the side of the vehicle that is low. The shim is to be placed under the lower spring seat; service shim (part number 389117-S2) can be used without a front stabilizer bar. If there is a computed side-to-side difference of 19 mm (3/4 inch) or MORE in the left/right wheel house openings, remove the high side spring from the vehicle and compare it with a service replacement part having the same part number.

If the free height of the original equipment spring exceeds the free height of the service part by 13 mm (1/2 inch), install the service part in this location. If the free height is less than 13 mm (1/2 inch), remove the low side spring. Compare the service spring to both of the original springs and select the two springs most evenly matched. Install the higher spring at the low side.

NOTE: Changing front ride height by adding the service shim also affects caster angles. Adding the 4.5 mm thick shim (Part 389117-S2 or equivalent) may reduce caster by up to 0.40 degrees on the side the shim is added.
