Got the gouges from cutting off the spring mount filled and ground. And, the spring mount welded in it's new home. Can't go any further till I get springs. Was going to finish the last body mount for the Jeep but, broke my band saw blade yesterday and don't have any more spares.

Hopefully the last modification to the frame. Body mount hole is too far back and the bushing wouldn't go in. Only really needed 1" but, all I had was some 1.5" so that's what I used.

All cleaned up and ready to put the body back on and see if my measurements were good!

Messing around out in the shop tonight, not really doing anything. Was looking at the OME YJ springs that arrived Thursday for my CJ.

Figured out why a lot of people complain about caster angle when doing the YJ on a CJ spring swap. The top plates where the axle rests are angle shims. Most people end up running 4 rear springs when they do the conversion, since the rear springs are heavier than the front springs. With those shims it would help to point the pinion up to compensate some for the lift.

But on the front it would still raise the pinion angle also, causing the caster to be less. If they are used with a stock CJ axle I'd either reverse the shims to get more caster or even get some flat plates made depending on how it does at the alignment shop. But, since I'm building my own axle and have already decided to do the cut and turn to correct the caster. I'll leave the plates where they are and just enjoy better pinion angle.

Got the OME springs under the CJ. Sat the front axle in place to see if I had the spring mounts in the right place. Fit like a glove! Just need the U-bolts to finish the install.

imga1128.jpg

Dug the 9" Ford axle for the rear out and tore it apart. Found 2 gaskets and silicone between the hog's head and the housing. While I was turning it trying to find the stampings on it to figure out the gear ratio. I noticed there was burrs on the outside of the ring gear. And, I noticed a lot of back lash so I played with it some more. Then found side play in the carrier instead of bearing preload. Threw my dial gauge on it, 0.044" side to side play! Was going to try to install the new Detroit Locker and gears myself, have never done a rear end myself. But, since I haven't found specs on the actual preload I was going to play with it some before I tore it apart. So, I'll probably take it somewhere and let someone that actually knows what they are doing build it. Figure it must be a feel thing like torquing head bolts on a iron head Harley.

Threw the hog's head back in until I can get the new axle shafts, spiring mounts, and U-bolts.

Ready to start welding my U-bolt skid plates.

imga1131.jpg

Got 3 out of 4 of them ready to drill, then ran out of welding wire. Wouldn't be so bad but, I just drove past Praxair yesterday when I picked up steel!

Been looking for a reasonably price NV4500 for the Jeep for the last 3 years. Rebuilt without a core they are going for around $2,500. Picked this one that was rebuilt 20,000 miles ago up off Craigslist today with a bunch of accessories that don't come with the rebuild that are out there. After adding up the accessories that came with it I'm into the transmission around $175, will have another $500-$600 in parts and labor turning it into a 4wd transmission.

Hence the 3 year search, Just wish it had been a 1998 or newer. The square top shifter boss does have a smoother shifter action.

So picked up up a 3/4" to 1/2" impact socket to use to make my 3/4" drive 29 spline socket. The 5th gear nut on a NV4500 is torqued to 300 ft/lbs. A lot of people will just engage the 3rd and 4th gear syncros to jamb the transmission to torque the nut, some just wrap a rag around the input shaft to hold it in 1st gear to tighten it. I'm not a fan of either as that 300 ft/lbs is transmitted to the output bearing as a side load, synchros, gears, etc. With the correct socket there is only about 1/2" between the end of the socket and the actual 5th gear nut.

imga1138.jpg

Cut the 1/2" drive stub off and ground everything smooth. Hit the top edge with the grinder to remove oxide coating where my weld will go. Ready for the freezer to help shrink it a little. The chrome version of this adapter is a slip fit but, didn't want to mess with chrome messing with my welds.

imga1139.jpg

Started with a cold 3/4" adapter and a warmed 29 spline coupler. Got it 3/4 of the way with a 2.5# press. But had to finish with my 8# press. Enough of a interference fit I can see where the splines inside the coupler gouged into the 3/4" adapter!

imga1140.jpg

All finished, my cost was 1/3 of a commercially made socket. And the commercially made sockets only engage about 1/2 the length of the splines one the output shaft, this one engages 100% of the splines. Might even put this in the blaster and then hit it with some flat black paint to make it look factory made!

Got my U-bolt skid plates drilled last weekend. Then finished up the "machining" today and welded off. While I was "machining" them with a die grinder and angle grinder I was wishing I had a CNC mill. Later on I decided I would be happy with an analog one!

imga1144.jpg

Ran out of carb cleaner cleaning the oil off the skid plates from drilling, so I finished up with brake clean, and yes I know you are not suppose to use brake clean because of the danger of making phosgene gas. I blew them off good and tried to make sure they were dry before welding, plus stood a couple of feet inside an open overhead door where if I passed out there was a possibility I'd fall into fresh air. Took this picture just to prove I lived!

imga1146.jpg

Got the first front one done and had to try it.

imga1147.jpg

Even the second one fit. Almost as though I measured it or something! Really hope the springs settle some when I get the power train in it. Right now with the axle set at the height it will be with 33" tires, I'm at 30" to the top of the frame!

Rear ones waiting for me to get my axle cut down.

Got my 9" rear end completely bare naked today. Little more cleaning and degreasing it will be ready to be cut down as soon as my new axles show up.

Yukon axle shafts, bearings, studs, and retainers showed up today for my rear axle. Don't think the post office was really impressed with the weight of the box! So next time I've got a few days off I can start cutting down the axle housing. Just need to order Torino style retainers since the axles are meant for the old style large bearing 9" that's the retainers that came with them. Getting closer to have my 9" service stand done, that's it sitting above the axles.

With only 1 day off, didn't feel like starting any big project. So I finished up the repair stand for the Ford 9". Normally would have probably not spent so much time on one. But, since I'm running one in the CJ and my oldest son is running one in his dirt car figure it will be used more than once.

Finally got the 9" cut down and placed under the back. Once the power train is in and the suspension in loaded I can set the pinion angle and weld on the spring mounts and the bearing housings. Hoping the springs droop a little when I get it loaded down. right now the way it sits, it will be 36" to the bottom of the door opening with 33" tires!

Draining the oil out of the next piece of this puzzle. Need to hit it with some degreaser and run it to the car wash Sunday. Then start tearing it apart to make it into a 4wd transmission.
