1. If the vehicle is equipped with four wheel drive (4WD), remove the front drive axle. Refer

to Differential Carrier Assembly Replacement (1500 FWD) or Differential Carrier
Assembly Replacement (2500 4WD) .

2. Lower the vehicle.

NOTE:

When raising or supporting the engine for any reason, do not use a
jack under the oil pan, any sheet metal, or the crankshaft pulley.
Due to the small clearance between the oil pan and the oil pump
screen, jacking against the oil pan may cause the pan to be bent
against the pump screen. This will result in a damaged oil pickup
unit.
