Ok guys, i now have 137,000 + mile on the ol f 350,7.3, cc,lb, man trans, 4x4, im getting ready to lift it here in a couple weeks. my question is. when can you tell that the u joints are ready to go or need to be replaced? i got down there and shook on them but didnt notice anything wrong. and with that split drive shaft i am worried " because around here it's not uncommon to see a truck on the side of the road with its drive shaft hanging out busted" so any ideas???? things i should look for????
thanks
thanks
