ADJUSTMENTS
ENGINE SUPPORT ADJUSTMENT
The right and left support assemblies are slotted to
allow for right/left drive train adjustment in relation
to drive shaft assembly length.
Check and reposition right and left engine support
assemblies as required. Adjust drive train position, if
required, for the following conditions:
• Drive shaft distress: See Group 2, Suspension
and Driveshaft.
• Any front end structural damage (after repair).
• Support Assembly replacement.
ENGINE SUPPORT ADJUSTMENT
(1) Remove the load on the engine motor mounts
by carefully supporting the engine and transmission
assembly with a floor jack.
