Thanks for the info on the steering box rebuild 70th Division. I figured I needed to stay away from Omix.

I ordered the rebuild parts from Ron and just ordered the worm gear from Staman. I'll be working on reassembly next weekend. This weekend I have been working on disassembly and cleaning the parts.

The steering box was filled with red grease which took a while to get cleaned out. The freeze plug was missing so who knows how long it was dripping grease!

Someone had replaced the sector shaft at some point with a repro one. I think I am going to swap it for one that I took from a CJ-2A steering box that had little wear.

I'm not sure what kind of worm gear was in there, but it had tons of wear. I also found that one of the bearing ball cups had a crack in it. All of that will be replaced.

Next step is to get the bushings out...

I've been busy moving, but now that I am mostly settled time to get back to work on the Jeep!

I did get the steering box rebuilt with a Staman worm gear and it seems to be working pretty well.

I am currently starting the process of disassembly and trying to figure out what pieces are original and what parts are new, repro, CJ, etc.

There is a boatload of bondo all over this thing unfortunately, but the heat gun and a scraper makes pretty quick work at it. I am planning on cleaning up the tub as one of the last parts of this project, so I probably wont do much more scraping until I am ready to work on the tub.

Got the fenders and grille off relatively quickly. Almost all of the bolts were replaced when someone rebuilt this in the 80's so they were not too rusty.

I am curious if the horn is original. It does not look like other Jeep horns that I have seen, but it looks to be about the right vintage. I did not see any markings on it.

I peeled some of the paint off the hood and it looks like there may be some original olive drab on the underside which is really cool to see!

Got the passenger seat out too and the floor underneath was pretty rusty. I am likely going to have to put a new piece of steel there in the future.

That's all for now. Hopefully I can keep posting my progress on this without so many long pauses in between!

Progress Update:

Got the tub removed with the help of my dad and the engine hoist. Looks to be in decent shape on the bottom. Typical rust on the support channels.

Got the engine out as well. Unfortunately it is not the original engine for this vehicle, I believe it is a CJ-2A engine. My current plan it to reuse this engine and put the T-84 back in since I do have that.

The frame appears to be in good shape with no major rust issues.

That's all for now...

JeepRDT,
You are making good progress. Thanks for the update and photos.

No, your horn is not original.

Dont forget to look under the hood for a registration number. Sometimes mechanics painted the numbers on the underside of the hood to make them easier to read when servicing.

Be ready for the sticker shock on restoring on of these WWII Jeeps. Do not let it deter you from doing it.In the end it will be worth it. Are you going for a factory, motor pool or combat restore?

DWesol - I'll keep that in mind before I strip the paint off. Never would have thought to check there!

eod1- I restored a CJ-2A a while back, so I know how expensive it can be. I'm just going to take it piece by piece as money allows. I want to go back to original as possible, but I am not sure if it was a Marine Corps or Navy jeep. Most people have thought Marines because of the hooks on the frame, but I think that could mean Navy as well if I am not mistaken. Anyways probably somewhere between a motor pool and combat resto. Definitely not going for a factory finish.

Started looking at the rear brakes and drums. Unfortunately someone put 11" brakes on it, so thats all going to have to be replaced with 9". I think the hubs are original, so I may try and get those off the 11" drums. I am hoping I don't have to rebuild the rear diff, but I have not taken the cover off yet to take a look at the condition.

Also got the master cylinder out. Looks like a repro to me, but i have not checked on the marking numbers yet.

When you replace the 11 inch brakes with 9", I would be interested in the 11' brake setup.

Here is a link to everything for the brakes but drum.

After Bead blasting and cleaning the old parts on my GPW. I had a lot of metal flaking going on as well. Then painting and buying all the hardware, my time and everything else, the second go around I just bought a set like this. My axles were extremely rusted and the flaking was bad. All the time I spent trying to save these parts was just a waste of time. Now when I look at a axle, if there is a lot of flaking going on I just order a set like this and get on with my build.
