Pinion seal?
I'm losing gear oil out the front of the diff. I'm assuming that its from the seal on the pinion shaft? Can I change this without removing the pinion? If I have to go that far I might as well go ahead and swap out my gears. I helped my stepdad make a run to the landfill and by the time I got home I'd lost all the fluid. It just started making a awful noise on deceleration/coasting. As long as I was on the gas it was ok.
I cant win with this truck, I was trying to keep it torqued up to keep the gears engaged while I was slowing down and wound up flooding it majorly to the point that the plugs were full of gas when I took them out. I thought I had screwed the carb, but after about 3 hrs. it fired up and I drove it back home. I think that is going to be ok, but I need to get the rear fixed now before I can drive it anymore. ![]()

If it's already making a noise, you're too late. Now's a good time to rebuild the axle with better gears. You can replace the pinion seal without removing the pinion, but it'd be a waste of time&money IMO. Get a master rebuild kit from a reliable source (richmond, superior etc) and do it right.

I dunno. Throw some Lucas in that diff with a new pinion seal and maybe you can get a few miles out of it

Thanks guys, I'm gonna have to try and change it b/c I dont have the money right now to do the complete rebuild like I want too. I'm going to talk to a guy at work tomorrow to see about a 3.73 rear he said he had and if its for sale. If I can do that I'll just swap the whole rears. Otherwise I'm gonna just change the seal and hope I didnt tear it up too bad. I'm gonna pop the cover and check everything out too.

Just a howling noise, no popping or anything. I was planning on popping the cover today to check everything, but it looks like its gonna be steady rain the next few days complements of Frances.
