amc 20 axle questions (pictures)

hey everybody. I started to work on my rear axle today. I cleaned it up good and opened up the pumpkin (this jeep was a mystery to me when I bought it ... no idea what was good or not) to inspect. this is what I found


all looks good to me, what do you guys think??
what kind of locker is this?


I think theres a leaky pinion seal, I dont know how much leak is too much. and I was wondering if these are changed from the pinion nut side?



I dont want to pull the axles to check seals and bearings at this point. would you recommend pulling them to see? It all seems smooth to me.

now for the big question.
the previous owner had some sort of spring over axle going on in the rear only. shocks mounting to brackets welded to the axle tubes. the spring plates have been cut off and welded onto the top...



The frame has been set up like this;

what would you guys recommend I do with this??? my new springs are superride 2.5" lift spring and the shackles are 0" lift. my new shocks are skyjacker hydro 7000.

sorry I hammered out all these questions at once... thanks for your help!

Not sure what you have but if my rear end was leaking like what I see in your pics and I had it out, I'd replace every seal in it. If you ride thru water or mud you don't want it getting into your rear end. From my experiance, water will get in faster than your gear oil will leak out if you ride trails where there's lots of mud and water.

I'll tell ya what I'd do if it were mine. Go ahead and spring for one piece axles. You can get 'em for about $200 and they come with bearings and seals. Then I'd go ahead and replace the rear brakes. You can get new hardware kits, shoes and new drums for under $250. I understand you may not have the coin right now but if you do, get as much done while it's sitting there. Clean it up and repaint too.

Im definetely on it as far as repainting and brakes, I think pinion seal as well. I am concerned with the one peice axles though... since it already has a locker.(what kind of locker is this?)
My biggest question is about the spring plate, and putting it back on the right side of the axle (no idea what angle and such) , as well as the shock mounts welded to the tubes and if this a good idea for the amc 20 ?? or should I go back to shock mounts on the spring tie plate (mine have been cut off)

it looks like a lock right locker. they work great but can sometimes act funny while changing lanes.

looks to be a lockright or ussie locker..Both a very good..Also you have 1 peice axles..be sure to get the bearings and seals for 1 peice axles...ya cant go to napa and ask for them I believe..I just stripped my hub yesterday after about a year of wheeling with a welded diff..Have axles to install so I havent really messed with them other than checking them out when I got them and reading online..

If I were to pull these axle to do seals/bearing, and there doesnt seam to be a leak other than the pinion, but if I do... Do I need to use a puller of some sort? are these the tapered ones? or will they slide right out? can't say that I fully understand one piece axles other than that they are a good thing.

one piece means that the hub and axle are all one unit, on the factory axles the hun was splined along with the axles. the two pieces were held together with a master key and nut.With bigger tires the hubs would strip the splines ans spine on the axle. Know for the puller ? You should be able remove the four bolts just behind the brake pads and pull staight out on the axle, the bearings are pressed on to the axle shaft so they should come with the axles. If they are alittle stuborn turn the brake drum over and slide it on backwards, tighten a few lug nuts on the wheel studs and slide the drum out and use it as a puller. Worked great for me. Hope this helps. jc
