Update
Kurt from Poly performance who handled my warranty claim was at KOH so he didn't get my axles shipped out until last Monday. Shipping to and from PP has been on their dime.
I continued getting other stuff ready like new fittings for the Master Cylinder and re-flared the lines to get the front circuit mated to the front brake lines. I exchanged my 3 ~AN braided lines for longer ones for the front calipers so they wouldn't bind when turning. Bench bled the MC and got the front circuit hooked up and bled (I kept my bleed line in for the rear circuit hooked up so I could pump the MC with it bolted in). Then I got sick for a day so I did nothing. And then the next day the tracking showed that my axles should be showing up. Not knowing what time they'd be here I was feeling well enough so I got started by shaving off the rear drain plug.
The plug is basically a threaded insert that gets welded to the housing. There is a factory hole punched in the housing that you can see from the inside.
I just cut off the head with a cut-off wheel and then started grinding what was left down to the housing. I was able to tap it out from the inside to break it free.
I cut a patch out with the angle grinder.
I made it snug so that I could tap it in and it stayed in place. Then I double passed the bottom, ground it down and smoothed it out with a flapper wheel. I double passed from the inside of the housing and cleaned up the splatter but did not grind that side.
Since everything was out of the axle it really didn't take very long. The bottom plug has a magnet (replace it as the fill plug) on it that I was loosing so instead I grabbed a magnet that I took out of broken microwave and put that inside on the bottom of the housing. Even if it were to slide there is clearance for it to go underneath the ring gear so it won't contact anything. It's quite a bit more powerful so it'll definitely catch any metal flakes possible left.
I ordered some axle bearings from autozone along with pads for the rear and another reseal kit for my steering box that showed up last week. My steering box is leaking quite a bit now and I'm going to give it one more shot, if it leaks again I'll have to pony up and pay for someone else to rebuild it. I took the race from one of the bearings I punched out and took some material off the OD to turn it into my bearing and seal driver.
I was pleasantly surprised to find they were actually Koyo bearings in a Timken box.
Finished cleaning the housing, knocked in my bearings and seals and had lunch. Conveniently the brown truck with a great sounding engine (newer brother to my 4bt) pulled up and dropped off my axles. I took those out to the shop and get the rotors, studs and spacers put together.
Nice to have a good bearing surface again and it at least looks heat treated as seen by the coloring on the flange.
Diff with new seals went in and I replaced the two lowest studs on the front and back of the housing with bolts for drainage. Axles and locker back in, rear brakes hooked up and bled, and nut popping heavy tires hoisted back on. Filling the diff with hypoid took forever but I finally got it dribbling out of the fill hole. Decided to run 85W-140.
Had a meeting to go to so I quickly got ready and took my test drive to the meeting. I'm going easy on the brakes for break-in procedures before I can get to a empty stretch and do some 60-20mph stops. Of course with functioning calipers they already felt much better and having driven it to work for a couple of days I can tell the brakes are going to be better than ever. Still get some vibs from the rear and I still have a loose TRE on the front so I'm not quite ready for any autocross but it's sure nice to have this stinky diesel back on the road. My wife now knows when I'm home.
Sadly with all this work I'm now ready to start working on the 14bolt and get that going. Hoping for an install by June.
I'm hoping to get my other 3 lbs package I got this week installed next week. Looking forward to that one.
