Front Lean

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

NOTE: Add 12 mm (1/2 inch) to the left 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, swap springs from side-to-side. If the lean condition follows the spring (lean now on other side of the vehicle), replace both springs with new ones.

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.
