ive seen a lot of sites selling luk for 599 but i don't know how good they are. i know 1 thing my truck picked a bad time to start needing parts with x mas here. i need a clutch and a turbo pedistal. how long does a clutch last in these trucks. mine only has 95000 miles on it. and i don't think it has done much towing. there r no signs of a brake controller being hooked up and no gooseneck hitch so i don't think that it should have went out already. unless my pedistal has been leaking oil down into the bell housing
