Just purchased and '05 XLT supercrew with 95k on it (yes I know about all the engine issues). My question is how durable are the rear-ends in these trucks? I have no idea if the previous owner ever changed the diff. fluids so I am thinking I am going to change the front/rear diff. oil as well as the transfer case and trans. fluids.
Anyone have any experiance or knowledge with these trucks and their drivetrains?
