    I'm at the point where I'm about ready to take the axles out and do a final assembly. I've been keeping all the parts for the axles in the boxes under a work bench. I decided to set up a folding table and lay out everything out.

    [​IMG]

    This way I can see what I have and what I need. I've been dry fitting a bunch of parts together and discovered that I was sent the incorrect brake pads. Emails have been sent so hopefully that will be sorted out next week. I also realized I didn't have wheel bearings for the front axle. So once the wheel bearings and brake pads arrive, I will have all the parts to assemble the axles. In the mean time I've been tinkering with some other tasks that need to be done. I needed to bend the transfer case shift levers a bit to get them away from the dash. In low range the levers were against the dash. I heated up the base of the levers with torch and bent them back slightly.

    Here both levers are in the neutral position.

    Here the front output is in the high range position.

    [​IMG]

    Here the front output is in the low range position. I had a mild panic when I thought about the trans cover interfering with the shift levers, but it clears just fine. When we put the shifter s together I left the interlock pills out so I can select the front wheel drive high range position. That way if something happens to the rear driveshaft or diff I can still drive home. Things are starting to get exciting... Hopefully I can keep making good progress. Thanks for checking it out. Laters.

    I managed to make some headway this afternoon...

    [​IMG]

    First I made a stubby little driveshaft out of an extra Bronco shaft we have laying around. It's sorta straight. I can see a decent wobble when it turns. I don't plan on driving with this shaft, I just needed to set the pinion angle.

    [​IMG]

    With the pinion angle set 3 degrees down from straight at the output shaft, I could set the disc brake caliper mounts in place. A little blast of air squeezed the pads on the rotor and aligned the bracket. Then I just tack welded it on. Repeat on the other side.

    [​IMG]

    Next up is the lower shock mounts.

    [​IMG]

    Everything is just tacked in place.

    [​IMG]

    Driver side

    [​IMG]

    Everything is looking pretty good. Tomorrow I'll put the U-bolts back on along with the tires and do a flex test to make sure everything clears. If it all looks good I'll take the axle out and finish the welding. Then assemble the axle guts with all the right seals and grease and stuff.

    Flexy Friday! I flexed out the suspension using my engine hoist and everything looks like it's going to clear just fine.

    [​IMG]

    Here's a close up of the driver's side rear tire peeking through the tail light hole. There's about an inch of shaft left of up travel. I can comfortably stick my hand between the shock body and the tire. If it rubs at the extreme end of the travel, I'm not too worried. It's not like I'll be driving fast with one tire fully compressed like that.

    [​IMG]

    Passenger side looking forward. When the driver's side tire had about an inch of shaft left, the passenger side had about the same amount of down travel left as well. I haven't mounted any bump stops yet, but I've measured and figured out which ones I want. Now to start taking the rear axle out and doing some welding and assembly...

    One step forward and two steps back... That's how it goes... All the mounts are straighten out and welded to the rear axle housing so I squirted some self etching primer and some satin black on... While waiting for the paint to cure I realized I had forgotten to place the brake line tabs and weld them on. Darn. Oh well. I can add them later.

    [​IMG]
    I got to this point ^^^ and I noticed something else was going wrong. See the bellows for my axle vent?

    [​IMG]
    I have these fancy inner axle seals that seal the pumpkin area from the axle tube.

    [​IMG]
    So the vent fitting needed to be relocated to the center section of the housing. No big deal. Just tear it all apart and drill and tap the new hole.

    [​IMG]
    Weld up the other hole. And so it goes... I'm ready to finish putting the whole thing back together, I just need some more silicone/RTV goop to keep the fluids in. Once the whole thing is assembled with brake lines and everything, it'll go back under the Jeep. Thanks for checking it out. Laters.

    Rear axle is assembled. I finished the vent relocation and built a couple hard lines to attach to the flex lines coming from the calipers...

    And I as I sit here posting this I realized I made a mistake. I wonder if you guys will notice...

    Caliper brackets aren't even?
    Missing shock mounts.
    No u bolts
    No u bolt brackets
    Center section is upside down and offset wrong.
    Shackle bolts are loose
    Muffler is in the way of a rear tank.
    What else... :confused:

    I guess it's harder to see. The flex lines from the calipers are too straight. As the pads wear, the caliper will slide on the pins. With the flex.lines pretty much straight, they won't allow the caliper to slide...

    Well that's what I get from trying to work on things while I'm stressed out about things to try and relieve the stress about things... :cry:

    I can fix the caliper bracket pretty easy, and the flex line is a simple fix. I'll get longer flex lines so I don't have hard lines running over the U bolts.

    I've got the front axle out now to finish up some stuff before putting it all together.

    [​IMG]

    The hydraulic assist cylinder is mounted, here at full right turn.

    [​IMG]
    And again at full left turn. Right now everything is all painted up and waiting. Maybe this week I can find the spare time to get it put together. Thanks for checking it out. Laters

    Waiting on parts...

    [​IMG]
    I'm honestly not sure how I missed this years ago when I took it apart, but it bit me in the butt. All set to put the front end together and this is what I found... Luckily new ones aren't too much trouble.

    [​IMG]

    The front axle housing is back on the leaf springs and I'm starting to play with the front shock mounts. I bought the upper mount from Mountain Off-road Enterprises in Colorado. It's designed for 1972 and newer Jeeps, so it's gonna take a little tinkering to fit this one. Not a big deal other than they advertise it being constructed from 1 3/4in tubing, it's actually 1 1/2in tube.

    Axle shafts put together...

    [​IMG]
    For some reason it really tried my patience putting those together. I know it's been over 20 years since I did axle shaft U joints, but good grief. Still making progress though. The spindle nuts should be here later this week. I'm getting pretty close to moving under it's own power...
