    I have not been spending much quality time with the Jeep as of late. The heat tends to kick my ass as I have had heat exhaustion several times in the past, and heat stroke twice. Also I thought my shoulder wasn't healing well from the surgery, but as it turns out it's my nerve damage from the IED that has been giving me fits. Same result in that my left arm hasn't been much use to me. I was able to correct one problem that I didn't like. The transmission sitting up too high. I designed a very short (half inch) box mount to replace the tall (two inch) zig-zag stock mount and had it welded up at a local machine shop.



    A cut out in the side allows me to reach in and hold the center bolt with a wrench to tighten it.




    The bolts drop through holes in the opposite sides big enough for the bolt heads. The transfer case sits at a more natural height, though with the SOA lift I will need to trim the skidplate for front driveshaft clearance at full droop.

    Well, nothing has got done on the Jeep all summer. Money is always tight during the summer because my wife is a teacher's aid, so no paycheck. Also my shoulder is NOT healing from the surgery I had back in the spring... I have just started my third round of physical rehab with it. The VA keeps telling me the surgery went well, and that it's useless to even get a new MRI for 1 year, because it will just show abnormal anyway... They say it's inflammation from the surgery. I've had 2 previous shoulder surgeries... they healed much quicker.

    Anyhow, I'm getting pissed sitting around, so I decided to start in on the axles. Well, first I took out the fuel tank. No photos, but I don't like how close the pumpkin is to it with the YJ springs, so I'm gonna get a 2" tunnel put in the front edge of it kinda like a transmission tunnel, to give it some room.

    First thing was to get one of the axles out. I decided to do the front one first. I lifted up the frame with the engine hoist,then worked the axle out from under, and onto a set of rollers.





    I have too much crap in the garage, so I decided to use the Jeep itself as the workbench for the axles... I rolled it around to the rear, then hoisted it over the rear frame rails. Using double layers of plywood, I set it on jack stands on the tail of the frame, and strapped it down.







    I set to work soaking every nut I could find with PB Blaster, and started in on one side. Being as my shoulder isn't up to snuff, and I haven't been able to stand long periods for years, I didn't get far, but I did make progress, so I'm good with that. I got one side brake caliper off, one Dodge truck automatic hub out, and that's where I got stuck. I stared in on the cotter pins, but the first one I came to was a PITA, and I decided to let it soak,and just call it a day. Just for fun, I tried the other side... pin came right out...

    Well, the trend of nothing going right is still active. I couldn't get the front axle apart, so I ended up taking them to a friend's house. I neglected to get photos, but same ole stuff. Used the cherry picker to lift them, backed the trailer into the garage, (that took a dozen tries) and took both the "good" one and the original to his place. He works as a mechanic by trade, so he can use the shop at work after hrs. Hopefully he can heat them up, and knock them out from behind with an air hammer.


    Today, I decided to give the rear axle a try. It laughed at me... Broke a bolt off in the caliper bracket for the left side. Then I discovered what was inside...





    Holy crap, I was driving this in the green CJ5 up till I tore it down to build this CJ7.

    Now, I do remember the green Jeep having a vibration in the rear when I was driving it. I figured it was the pinion bearing not getting enough oil due to how far the housing was rotated. I think I was right about that. It won't allow the carrier to rotate so I can get to the cross pin, or "c" clips... If you grab a rotor, you can twist the axles,and see the carrier try to move, but the pinion is frozen.

    Can't even budge it with my tanker bar.



    Any ideas here? Or will I end up letting Ryan take this one apart too...

    By the way... notice the nice repair job on the yoke... 3 bolts one size, 1 another. I'll change that out anyway as I'd rather have the u-bolt type than the strap type.



    How the hell do you get an axle apart when you can't rotate the carrier?

    Fill that thing up with atf for a few weeks. Maybe itíll penetrate enough to loosen it up?
    If not, get a hot wrench!

    Next thing I'm gonna try is taking the yoke off, and giving the pinion a good whack. See if it will break free enough to spin.

    The good news is the pinion now turns. The bad news is, it doesn't matter...

    I took off the yoke, put back on the nut, and gave the pinion couple good raps. After that I could turn the diff no problem. I got the crosspin bolt out, and started to remove the pin. Bang, all progress once again came to a screeching halt. The ring gear is so fat, it's in front of the crosspin. The pin only came out a bit,and smacked into the teeth of the ring gear, leaving me to wonder hoe the hell they put it together...



    I looked inside, and sure enough, without getting the pin out, I don't see how I can get the "c" clips out to remove the axles...



    Really starting to hate these axles...
