I've looked over the Manuals, and it says to remove the cover, then remove the lever shaft, loosen the jacket tube clamp, take tube off, then the manual says you can pull the wheel tube (splined or keyed, which mine is splined) out of the gear box.
Here's my question. I'm at the point where I can "pull" the wheel tube out, but it really isn't moving. I can get it to move probably about a quarter of an inch, but then it won't budge. Am I doing something wrong? Is that splined into the cam and maybe that's why it's so hard to take out? What am I missing here?
I also believe I have a CJ5 steering gear that is in the same boat, and I can't get that to move at all! I just need the tube out of the CJ 5 and put it on the A1. Everything else from the A1 seems serviceable besides the easily replaceable parts (bearings etc.). _________________ Dave

I'm having trouble understanding what parts you are referring to. What do you mean by "lever shaft" and "wheel tube"? Pitman arm shaft, and steering shaft?
As far as I know and can tell from the parts manuals, the M38A1 gear is constructed the same as the M38 gear, just a different ratio. The cam on the end of the steering shaft is welded to the shaft. You have to remove the upper housing from the main housing (three cap screws) to be able to pull the shaft assembly out. This is covered in Section II, Rebuild of Steering Gear in the M38 TM 9-8014B Power train, Body & Frame manual, page 155. _________________ Jim McKim

I'm at that point where I should be able to "pull" it out, but it will only move a quarter of an inch. I was looking in the ross steering gear manual when I looked up the technical names. I had my TM out in the garage though so I apologize on the confusion of names. I didn't think it would be all that hard to pull it out since everything was held in place by bolts but it won't budge. I don't want to break anything so does anyone have any suggestions? _________________ Dave

If I remember right there is a ring, probably 'N', that holds the bottom of the shaft in place. If I recall, when I took mine out, I had to push the shaft out with a little force to pop the end out of that retainer ring. _________________ Brett

I'll have to check on that ring this afternoon! There was so much sludge/oil in there that I could've easily missed it. So basically take that ring out and then I'll be good to go? Sounds good enough for me.
Would I be able to use the CJ5 steering shaft to replace the A1 shaft? THere are no more threads on my A1 shaft for the steering wheel nut to be attached. I have read how ratio's are different between different vehicles, but the CJ5 was the civy version of the A1 so I was wondering if it would work? Also, how exactly can I tell if it is a CJ5 steering gear? I was told that by the person I bought it from (I wanted the steering wheel and for $50 I couldn't go wrong), but how can I verify? Thanks guys for all of your help! _________________ Dave

Once you get the sector shaft out, you will remove the tube covering the shaft by loosen ing the clamp bolt and pulling it off (unless the bearing at the top of the steering shaft is rusted to the shaft). Then loosen the 3 cap bolts at the top of the housing. There is nothing else holding the worm (steering) shaft in the housing. The lower bearing is held together with a circlip, but will fit through the housing with a little work (and maybe a hands from a friend). It would be best to remove the whole steering gear from the jeep to rebuild it - will be a pain to replace the bushings (which is necessary for a rebuild) installed in the chassis. _________________ Matt

I've removed the covering, the 3 cap bolts from the top, the side covering, the shaft (Part XX, that fits into the cam and turns the pitman arm). It isn't budging. I'm going to have a friend help and hopefully with two people pulling, it will come out.
The steering gear is removed from the chassis. It would be a pain to rebuild while still installed.
Any thoughts on using the CJ5 steering/worm shaft on the A1 steering box? Thanks. _________________ Dave

Oh, ok - yeah, definitely easier out of the vehicle. The only thing that could be holding it in might be the lower bearing being rusted in place? If you are getting about 1/4"of movement, that could just be the slop in the bearings - the races could be rusted in place. With that being said, can you see the races moving - they aren't a press fit, just a slip fit. If the races aren't moving, you might be able to spray some pb blaster or something and figure out a way to jar it loose. Just some thoughts. _________________ Matt

Awesome. It's got to be the bottom bearing then. The top one moves and starts coming out. The bottom one on the other hand.... not so much. I'll give the PB or Slikroil (I think that's how it's spelled) a try and see if that helps! THanks! _________________ Dave

Yep, if it isn't moving, thats prob your culprit, because there just isn't anything else there to hold it in. _________________ Matt

Hey Dave,
I just remembered that a put some pics of my steering gear rebuild on my blog when I did mine. Here is the link:
http://wilfreeman.wordpress.com/2012/11/08/steering-gear-is-almost-done/
There's a couple more pages with steering gear stuff on there too. I'm getting ready to dive back into the steering shortly - I'm going to be rebuilding my bellcrank because I think the casting is worn. Still getting about 1/4"of play in it. I also have an NOS pitman arm to install. _________________ Matt

Wes, Thanks for the part numbers. Thanks Will for sending your rebuild link. I'm going to use that in the near future to help me out as well! Now i just need to take some pictures and update my build thread! Are either of you going to Aberdeen this year? I wouldn't mind meeting some other members of the site to match a name with a face. _________________ Dave

I try to include some stuff that might be of some use to people on my blog. Hopefully, followers of it can learn something from my trial and error.
I'd love to go to Aberdeen, but it's a little far north for me. I just got back from a rally in Denton, NC this past weekend - pretty good time. _________________ Matt
