Again, thanks! | | | | Joined: Nov 2005 Posts: 123 Shop Shark | | Shop Shark Joined: Nov 2005 Posts: 123 | I am working on my 1950 3/4 ton p/u. I have re-done the brakes and am installing new lines. The body parts have been removed to be cleaned and primed. My questions are these...do I need to remove the rear cover of the rear end in order to drain it? Is this a smart thing to do???drain out the old fluid?? If I have to remove the cover I might as well take a look inside right? If so what should I be looking for? Is there anything I should check to make sure the rear end is ok or is there anything I should replace???it had 4.57 gears. any ideas would be welcome.

Best way to drain the oil is to remove one of the bottom cover bolts. It certainly won't hurt to remove the cover and clean the bottom of the housing. Either way, when you put the bolt(s) back in they need some sealant on the threads.
Also check the vent for obstruction. It's on the top of the housing, driver's side. It unscrews, 1/4" pipe thread. Has a sheet metal fitting to keep out the dirt. If it's plugged your gear lube will expand when warm, overpressure and blow out the axle or pinion sealss.
