What is the manufacturer of this part. Is it US made? I’ve heard about worm gears surface issue and cracks on aftermarket parts. I would be more confident if I could get an US made part for such critical system.

Does this work for 1970 cj5, with manual steering, also ? If not, do you sell that part for a 1970 cj? Plus all the other parts to rebuild the steering box?

Willys Jeep Parts Tech:
If yours is the 7/8" sector shaft then yes but typically after 1966 your the 15/16" sector then 807480 which was used more when the V6225 engine was introduced.

Do you sell the inner shaft (tube) without the worm gear? I am planning on changing to a Saginaw system using the factory column, but will need to cut it anyway and do not need the gear.

I have a cj5 1964 with Steering Gear Box Number Ross T125996, but I need change the Steering Gear box tube & worm . What is the part number for the correct?

Willys Jeep Parts Tech:
If you are a 1964 - then you should have a 7/8" diameter sector shaft. This is the proper tube and worm gear.

I have a early 60s cj5 with a 15/16 sector shaft is this the worm gear I need? and do you get your measurement from the bottom of the shaft to the bottom of the splines or is it from the bottom to the top of the threads

Willys Tech:
It would have to be a late 60's CJ-5 to have the 15/16 sector shaft. Pre 1965 they all were 7/8. I would double check your measurement. You measure the smooth part of the shaft.

I have a 68 with the big Ross box 41.5 worm gear shaft, 15/16 sector shaft. What is the part number for the correct worm gear shaft. All show for 7/8 box.

Willys Tech:

Willys Tech:
This is for the 4-134 engines with the 7/8 diameter sector shafts.

steering is sloppy amost half turn before wheels move 49 willys

Willys Tech:
This should solve alot of your problem. Also use part number: 805123

i have a 1948 cj2a the tag on fire wall serial number is 89062 what is the right tube worm gear to use A8838 or 647693

Willys Tech:
I usually dont like to go by serial numbers. Willys seemed to use what ever is lying around on the factory floor with CJ-2A's. The best way is to measure the length. Either 41.5 or 40.5. If yours is 40.5 use the A8838. If yours is 41.5 use this one.
