ISSUE:
A rear axle fill plug that is hard to remove may be caused by the type of plating used on the steel fill plug. The steel fill plug has a negative
reaction to the aluminum rear axle cover.
ACTION:
Use the following procedure if the rear axle fill plug is difficult to remove.
1.
Using a heat gun, apply heat for about 60 seconds to the aluminum that surrounds the fill plug. The heat range should be 500~ to 750~ F.
CAUTION:
DO NOT USE AN OPEN FLAME TO HEAT THE REAR AXLE FILL PLUG.
2.
Immediately remove the fill plug by using a 3/8" flex handle.
3.
When the fill plug is reinstalled, tighten it to a torque of 23-25 ft.lbs. (34-47 N-m).
