I have a 52 CJ3A, it is a Navy APU jeep. Looks like there are several M38 parts on it. I am looking for the seal on the steering gear case. The gear case is a Ross # 122983. The shaft measures 0.875. Is the seal sold separately?

Willys Jeep Parts Tech:
Yes, that is a 7/8" Sector shaft. We have all the individual parts for it too.

What is the total length of this sector shaft?

Willys Jeep Parts Tech.:
6 inch like original.

What is the manufacturer of this part? Is it US made? I’ve heard about failures on aftermarket sector shafts and I’d be much more confident if I could get an US made part.

Willys Jeep Parts Tech:
If you are after a US part for this, you will need to go through a salvage yard. Give us a call.

I have a 50 cj3a the sector shaft broke off at the spline coming out of the steering box. I am ordering a new one but what would cause this to happen. We normally only drive it on pavement. I noticed the steering was really sloppy so I was taking it home. It broke taking the corner to my home. Jumped the curb and didnt hit anything but was going 40 just before that. Putting this out there for others in case they would experience the same sloppy steering. thanks

Willys Jeep Parts Tech:
After 70 plus years of wear and tear and abuse Im sure its possible.

Hello, I would like to know if you ship outside the USA, for example in my case to Barcelona (SPAIN)?

Willys Jeep Parts Tech:
We ship daily international. Thanks!

We just dismantled the steering box for a 1949 pickup. The sector shaft is worn but measures 0.932 (59/64) where there is no wear. Part number is TA124997. You list 1 and 7/8 shaft kits. Will one of these work for us? Will it fit properly into the worm?

Willys Tech:
The Willys Truck in that year's sector is only available good used. Please call us toll free.

Does this kit (Steering Gear Box Sector Shaft Repair Kit 7/8) fit the M-38 Military Jeep? Above you indicate that it fits 41-66 MB models. However, according to my information production was stopped on the MB models in 1945 or 1946. The next Military model was the M-38. I am restoring an M-38. The steering box has too much play and needs overhauling. Do I need this kit for the M-38?

Willys Tech:
Please see above for individual vehicle year listings. The kit for the M38 is part number: 804533K

Do you need special tools to rebuild the steering gear box on a 1960 Willys Jeep?

Willys Tech:
No, a simple vise will do the trick. No special tools required.

what typ reamer will i need thanks

Willys Jeep Parts Tech:
Some use oil and light sand paper to hand fit. Some people use a wheel cylinder honer to fit.

Would i need to ream the bushings?

Willys Jeep Parts Tech:
When you press them in evenly it is common for the ID of the bushing to mushroom in just a bit. So its typically to hand ream just a bit to get a nice tight slip fit.

How many teeth on the sector shaft

Willys Jeep Parts Tech:
These appear to be 36 spline like original.

I have a '71 CJ5 4 cylinder. The sector shaft is 7/8". Your online catalog indicated the larger shaft for that year. Is item 805123 the correct part for me? The old shaft has no. T124998 on it.

Willys Jeep Parts Tech:
If you have the 4-134 F motor then the 7/8" diameter shaft would be correct for you.

i have a cj2A and would like to know if this item is the correct one for a ross T125996 stearing gear, thank you very much,

Willys Jeep Parts Tech:
I cant cross that Ross number but this is the proper one for the CJ-2A with the original steering gear box.

Could you tell me the weight of this item please?

Willys Jeep Parts Tech:
It weighs approx 2 pounds boxed.

Do you also have worm gear bearings, shims ,and bolt gasket washers for cover plate in a kit with the sector shaft and bushings and gasket

Willys Jeep Parts Tech:
We can definitely help you with all those items. Give me a call toll free and we can go over it. 888.648.4923. Thanks

What’s the correct alignment for the selector shaft to Pittman arm please. I ordered the kit yesterday.

Willys Jeep Parts Tech:
You have to align your wheels and have the steering wheel in the center position on the worm gear. Call and ask for Mike M. I can walk you thru it.

Do you carry the horn wire tube as part of any of the steering box rebuild kits?

Willys Jeep Parts Tech:
Depending on what vehicle you're working on, we do carry everything for the horn. Give us a call toll free and we can figure it up for you. Thanks

I have a early1955 CJ5 serial #57548 10040. I don’t think it has the correct size steering box. The sector shaft is 15/16” the steering tube /worm gear is 41 1/2” long. Box #TL122995. I also have another steering box #T122983 with 7/8 sector shaft but the steering tube/worm gear is only 38” long. Which one would be the correct one to rebuild.

Willys Jeep Parts Tech:
Please email I can help you ID your sector shaft for you. I'll need to get some additional info.

My 63 JC3B is going to receive the kit# 805123. It has an upper wobble in the sector shaft & some play in the steering wheel at the center/straight wheel position. If the replacement kit does not remove this wobble would a "Tightsteer" kit #T161000, remove it? Thank you.

Willys Jeep Parts Tech:
This kit really should take care of the issue. I would also make sure you properly shim your gear box and see part number: 646084. The tightsteer kit would do the rest if your still having any issues.

Hi products 805123 and 805123A - are they identical? (steering gearbox sector shafts)

Willys Jeep Parts Tech:
Yes, it is the same part.

Im restoring a 1960 Willys Jeep Dispatcher DJ-3A and the steering gear box has a lot of play in it. There is no listing for that model jeep. Which rebuild kit would fit this model.

Willys Jeep Parts Tech:
We can probably help with some of the items you need. Please email and we can go from there. Thanks!

I recently purchased the steering gear box sector shaft repair kit and have a couple of questions that maybe you can help me out with. The old bushing came out fairly easy, but, the new bushing just fell right in and the shaft was a pretty tight fit, shouldn't that be the other way around. I'm afraid that the shaft and bushing will rotate inside the gearing box. I would think the shaft should rotate in the bushing to save wear on the housing. Also with the cover off and turning the wheel back and forth, the sector shaft will move and cause the nipples to come free from the worm gear. With the cover on it keeps the sector shaft from moving back and forth. I assume that is how it is supposed to work, but, worry that would put a lot of pressure on the steering box cover, is that a concern? Should there be a bushing on the outside of the steering box on the sector shaft and pitman arm to eliminate this lateral movement?

Willys Jeep Parts Tech:
Please call and ask for Mike M. I can help you trouble shoot and ID your gear box.

Hi, I have a doubt, my jeep is a Kaiser Willys CJ-5 1964 serial number 8305 164072 has a problem with slop. I don´t know what diameter sector shaft (7/8" or 15/16") cus´ both item 805123 and 938194KA mark to CJ-5 1964

Willys Jeep Parts Tech:
In 1965 you could have either. Typically if you have the 4-134 F engine its a 7/8" and if the V6225 they used the 15/16" sector. Its best to measure.

Is the end of the sector shaft (the end that mates with the worm gear) fixed to the actual shaft? I've determined that my "spins" under heavy loads and and the wheels will not turn. This can't be normal, right?

Willys Jeep Parts Tech:
The sector shaft is one piece per the photo. Sounds like yours is broken possibly.

Hi Mike Please email all the part numbers for this steering repair kit. Thx regards Donovan

Willys Jeep Parts Tech:
Please email or call us toll free and we can help you ID what all you need for your Willys Jeep.

I have a1951 cj 3a developed the dreaded death wobble, king pin bearings seem fine thought about rebuilding the steering box, any advice would be welcome, thanks

Willys Jeep Parts Tech:
I would go thru the king pin and wheel bearings as well as steering. You will want to install part number: SJ-7100 for sure.

Do you have access to the "Cover and Tube" that goes into the gearbox for the horn wiring to pass through? If not how do I keep oil from leaking around the wire?

Willys Jeep Parts Tech:
That is available good used. Please call us toll free.

What do you put in steering box ,It has grease in it now I have read to use 90 wt instead .which one do you recommend Thanks

Willys Jeep Parts Tech:
We typically use 90 weight but a lot of people use grease as well.

I have a MB chassis and I removed the steering box. I got the M38 worm gear from you folks. but it doesn't match with the pins on the sector shaft. So I looked the Ross part numbers The box is TA122985 (which appears to be M38) the sector shaft is TA124977 (which is 29/32 and the pins are 1.5 inches appear) The worm gear I have is TA 123001 (which appears to be a light truck) I want to what parts I need to make this work again Thanks

Willys Jeep Parts Tech:
Sounds like you may have an M38A1 gear box actually. Please call us toll free we can try to help you.

I have 58 CJ 3 B (navy) and the steering box may not have come on that jeep. It is a Ross T 122983 and T 125998. How can I identify the box so that I can order parts?

Willys Jeep Parts Tech:
Please email the diameter of your sector shaft and the center to center on the nubs that ride on the worm gear and we can help.

I ordered and received part 805123 for steering gear box. It did not come with "sector Shaft oil seal" per the video or with either of the two worm gear ball bearings and race. do I need to order part 646084? does this include one or ball bearings and races? Part 805123 came with an ignition switch and keys? Why???

Willys Jeep Parts Tech:
You should have gotten the oil seal with it. The 646084 is a separate item. Please call us toll free and we can help.

Does the steering gear box have to come off the frame to be able to replace just the sector shaft? I had the nipples shear on the shaft working it in heavy snow on a rough trail. Fender is off, pitman arm is off, gear box cover is off. What stops sector shaft from coming straight out and replacement going right back in? Anything I'm not seeing?

Willys Tech:
You can probabaly take the fender off and then be able to slide the sector shaft out for extra clearance.

Will this kit work in a 71 CJ5?

Willys Tech:
938194KA is the part number you want for 1967-71 with the 15/16 sector shaft.

When I am driving my willys cj-2a, I steer and it makes a sort of clicking noise and occasionally locks up. Does my steering gear box just need lubrication, or does it need replacement parts. If that is the case, what parts? Thanks!

Willys Tech:
Sounds like you need to go thru your steering and see what is going on. I wouldnt drive it again untill you do. I would check your gear box, tie rods, bellcrank, king pins, ect...

I see the cut off year is 66 for CJ-5. Is it possible that it will work with a 67 CJ-5?

Willys Tech:
Yes sometimes if you still have the 4-134 engine. Its always good to measure after 1966. Before then it is always 7/8 after it could be either.

I have a 1956 CJ5, with a loose on the steering and also is very hard, this kit works for my jeep?

Willys Tech:
Yes this will be the proper kit for you Jeep.

I have a 46 CJ2A and have very much free play in my steering when the steering wheel is moved from left to right. where do I start the repairs? also how can I be sure the vehicle is what the seller said it is. the vin plate came loose with the jeep but the numbers match the title. vin plate supplied is #CJ2A734550.

Willys Tech:
This is the first part you need. It will take most of the slop out of the gear box for you. I would also get part number: 646084 too. We do have 'Tightsteer' kits too that are part number 7161000

Getting ready to order this. Have my old shaft and bearings out. Is there a seal that goes where steering wheel input shaft enters the steering box - didn't really want to take the that out if not. Thanks, Bill

Willys Tech:
Yes there is a oil seal that goes where the shaft comes out. It also come in this kit too.

i am looking for a sector shaft that fits a 1953 m38 A1 military jeep/ can you find one?

Willys Tech:
Those are only available used right now. We have all new bushings, oil seals ect for that box.

It seems my system of haphazardously placing parts here and there has failed me and I have misplaced the nut that goes on the end of the steering sector shaft. Would you happen to know the size and TPI of the nut that goes on the sector shaft?

Willys Tech:
It is a think walled nut. They are only available used really. Please call us toll free. We can probably help.

I cannot seem to find the contact bushing that isright next to the slot for the horn wiring, and several inches above the worm gear. i believe I have ordered everything else i need but that.

Willys Tech:
You want part numbers: A302 & A302B

I have a 1965 cj5,It pulls to the left real bad.what would I have to replace? complete rebuild?

Willys Tech:
This would help. I would also take a look at your tie rod ends.

I Have 1948 CJ-2A Stock Drive Train. Steering Wheel has Quite A Bit Of Play In It. Jeep Goes Down The Road Fine. No Shimmy Or Shake. Would This Kit Sove My Problem? Rest Of Front End Seems Tight. Thanks For Your Help.

Willys Tech:
This and part number: 646084 will take care of it for you.

We have a CJ2A We removed the worm drive bolt on the bottom of the steering box. We can't get the bolt to thread while trying to reassemble the unit. What are we missing? Also how mant ball berrings should there be on each end of the box. Please help!

Willys Tech:
Please call me toll free. I can help you on the install. On the ball bearings there are 10 or 11 upper and lower each.

I have a 1968 CJ5 with 225 V6, do you offer a kit to repair my Ross box?

Willys Tech:
Please call me toll free. We do have some of the components.

Is the Ross steering box the factory steering box for a 1946 CJ-2A, I have serial number 26624 and all of the steering parts are factory original.

Willys Tech:
Yes that is correct.

I need to replace the sector shaft from my Ross steering box. I have it completely disassembled and would appreciate if you could clarify the part number for me. On the sector shaft the number T124989 is stamped, is this the same as your 805123? How do I determine amount of shim required during installation?

Willys Tech:
As long as its one of the vehicles specified it is the right kit. The shim should be set so that the worm gear has some drag but does not grind on the ball bearings. Please call me toll free. Im more than happy to help.
