Steering coupler and gear problem
Hello
I have a leak on the input shaft of the steering box and the rag joint is broken, so i decided to change the steering gear and rag joint [a brand new rag joint and coupler] Well the rag joint i got from LMC doesnt fit the input shaft from autozone, it should because the difference in diameter is 0.002", i tried to tap it in with a mallet but the coupler started to scrape the splines on the steering gear and cant put the old rag joint because the old pump and the coupler are of a smaller diameter. Counted the splines on the rag joint and thats 23 and on the steering gear 30-31. Besides i tried calling LMC before i ordered the rag joint and for some reason they sell parts but dont have tech support ![]() Any sugestions, even if it implies rebuilding the old steering gear... ![]() PS any recomendations towards a steering shaft convertion [the one with u-joints] will be much appreciated.

Re: Steering coupler and gear problem
It cant be bud, LMC part# 34-0746 "F" states is a 68-72 and for integral p/s.
Actually the old rag joint is from manual p/s and it did fit the smaller OD p/s gear, but it was old and i lost the woodruff key so the splines are a little rounded off.

Re: Steering coupler and gear problem
Any part numbers... or something, cause apparently theres a vast variety of rag joints and gear boxes...
My old steering box has the casting number: 7802644

Re: Steering coupler and gear problem
that is the same number on my power steering box, I believe it is newer than 67-72 so maybe the year difference is you issue.

Re: Steering coupler and gear problem
Ugh.. .This reminds me of one of my latest frustrations with the popular resto shops we all deal with! Well, my case sounded similar to yours.
In my case I have a 68 burb with manual steering, and I was dealing mostly with Orange County Car&Truck shop. Well, I ordered the rag joint for my rig. What did I get? a rag joint for another version of manual steering, being that the one I got had a section of no teeth where as mine required teeth all the way around. On the phone this shop sucked @$$, so I had to drive in and put my old one in their face. They ended up getting the right part from their car side of the house! The guy at the counter said he didn't understand why the truck counter didn't have this version in their shelves. I told them that there are basically two versions of manual steering boxes, both requiring two different rag joints do to the teeth design. Not sure I helped ya, but I just had to vent.

Re: Steering coupler and gear problem
Oh man I just went thru this TODAY what a coincidence. Well I got my input shaft from Classic Performance and the rag joing from Advance Auto Parts.
I used part number 201 from a company called "Lares" it worked like a champ.... Manual rag joints are SMALLER than the power steering ones.

Re: Steering coupler and gear problem
Al,
The rag joint you got from Advance, was the part no. 201 for power steering or manual. They list a part no. 200 as well but don't define which was is for manual and which one is for power. Thanks. |

Re: Steering coupler and gear problem
If your old coupler fits ok, just get a rebuild kit for the rag joint and fix it. You just replace the rubber and it's good as a new one.

Re: Steering coupler and gear problem
I had the same problem. I had a manual steering box rebuilt and thought it would be a direct replacement for the one I had on the truck. I was wrong, I ended up going to advance and ordering all the rag joints that were listed between 67 72, brought in the rebuilt box and found the one I needed. Only had to pay for the one I took out of the store. I still have the one from LMC that doesn't work.
Learning curve from a 40+ year old truck is always there.
