Services Performed
- Road tested vehicle and felt minor shudder on initial turn while vehicle was cold. Issue went away on subsequent turns. Inspected vehicle on hoist and found no obvious issues. Suggest replacing rear diff oil and adding bottle of friction modifier to rear diff as a starting point. Upon rear cover removal found no obvious issues with rear diff. Recommend driving for a period of time for friction modifier to absorb into limited slip clutch packs to see if issue goes away. At this point the vibration is minor, and short-lived. May be difficult to pinpoint the cause. Any issues with shudder/ vibration are usually a process of elimination and this is a starting point.
- Remove the needed shields and covers to gain access as needed to the rear differential cover bolts and cover. Clean the gasket sealing surfaces and cover. Clean out the rear differential and reassemble with new heavy duty sealer and/or gasket. Fill with New fluid.
