How do you remove front wheel drive on a 1993 suburban 4 wheel drive 5.7 liters V8 to change oil pump?

You don't need to. Just unbolt the motor mounts and lift the motor up. Get under the truck & remove the oilpan bolts & remove the oilpan. remove & replace the oil pump. ake sure when you put the new sump screen on the new oilpumop, you measure the sump depth in the oilpan. Failure to adjust this correctly within 3/8 of an inch will result in low or no oil pressure.
