Toyota Repair: OIL PAN GASKET REPLACEMENT, pan gasket, oil leaks

Question
HOW DO I CHANGE THE OIL PAN GASKET ON 1991 TOYOTA 4 WHEEL DRIVE TRUCK 3.0 6CYL EFI ENGINE

Answer
There are two ways to go about this neither one easy, remove the engine, this may be a good idea because the rear main seal can be replaced at the same time and any other oil leaks can be dealt with a lot easier with the engine out. The other way is to remove the front differential to get the oil pan off, I personally don't like doing it this way because after all that work the rear main seal may start leaking later which would require removing the engine or transmission,I would remove the engine and repair any oil leaks that are obvious and replace the rear main seal.
