The front differential is secured to the left side of the oil pan and the right front drive axle innrer bearing pedestal to the right side. To replace the oil pan, first lower the front subframe and then detach the front steering knuckles, the drive axles and differential. Starting the process is done by removing the negative terminal of the battery while being cautious enough to go through the battery disconnection cautions. In the engine compartment plenum chamber, remove the ventilation microfilter and plenum cover and then 'snap off' the plenum seal and the plenum bulkhead. Then remove the air intake hood on top of the radiator and the upper half of the engine cover and the air filter housing. Lift the car in the engine hood assembly position and continue. Lose the splash shield and front end reinforcement under the engine, then fabricate an engine support brace across the engine compartment and lift the engine about 1/4-inch off its mounts. Removing from below, take off the right and left engine mount upper nuts, the steering knuckles, the front-drive axles, and the front driveshaft. Place a marker on the direction of rotation on the alternator belt before removing it, unscrew the power steering pump and suspend it to one side but do not disconnect its lines. Remove the electrical harness connector at the oil level sensor and, if necessary, drain the engine oil. Take off the return hose on the crankcase breather oil separator and the dipstick guide pipe as well. Disconnect the key of the steering spindle from the rack and screw back the left and right steering knuckles loosely on the two bolts from the front strut, the front control arms and the tie rods connecting them to the steering knuckles. Place the front subframe on a block of wood on a transmission jack in a way that will allow the steering rack remain bolted on the front subframe. Slowly lower the subframe again while being extremely careful not to pinch or squash the power steering lines, although it should provide enough support. Take off the front differential and the last screws of the oil pan, to be able to pull the oil pan backward to slide it out. If the oil pan cannot pull apart, gently strike with rubber mallet to free the part and avoid damaging it with a pry bar. Scrub the sealing surface of the engine block, and paint beads of 3-Bond 1209 sealer or another one on the timing cover so as well as rear main seal carrier weld lines. On reinstalling oil pan reinstall is clean the gasket material from the sealing surface and use new gasket insert oil pan bolts and tighten front oil pan bolts and the last is to tighten the transmission bellhousing bolts. The rest of the installation is performed in the backwards order of the removal. Add oil to the engine, start the engine and look for any drips, always following the right procedure of the front end reinforcement installation. When through with this procedure, there is no need to adjust the front end any further.

Tap lightly with a rubber mallet to break it free, avoiding the use of prying tools.
