D Height Adjustment
Important: The D trim height should be the same for the left and right side of the vehicle. The D trim height requires adjustment if one of the
following criteria is met:
^
The measurement from either side of the vehicle is out of specification.
^
The measurements fall within specifications, but the right and left sides are not equal.
1. Important:
^
When adjusting the spring adjuster bolt, the J 42743 must be used to prevent damage to the rubber shear pad on the end of the bolt.
^
One complete turn of the spring adjuster bolt is equal to 2 mm (0.079 inch) of trim height.
Use the J 42743 (1) to relieve the tension from the spring adjuster; then adjust the D trim height by turning the spring adjuster bolt.
