2002 Toyota Tacoma crew cab needs work

2002 Tacoma this truck has to be in 4 wheel drive in order for it to drive.i think the problem is the rear differential it was leaking and it drove with no fluid.the engine and transmission are fine.it also has a brand new frame from Toyota under the recall.i just installed a brand new rear number.there is some rust on the rocker panels but not too bad.the truck needs a good wax job and interior cleaning.i don't not check emails much!!!so it's best to call me at 201 874 2367
