When buying a steering coupler (rag joint) recently through Advance Auto Parts, I had to order one for a 1980 F-250 4x4. All of the "proper" 70's era listings showed the incorrect one. The one I originally got had a 1/4" dia. stub on one side and a 3/8" dia stub on the other. The one for the '80 was the one I needed with both 7/16" or 1/2" dia posts.
I had to do replace one in a '76 recently. No problem - and the part was as you described.
Is your column/shaft factory or has there been an "upgrade"?
Both trucks I had, 78 4x4 and 79 4x2 were both the same with the fat stubs instead of the skinny stubs. Not sure what the deal was. Oh well, I got the right part and I can steer my truck again :-)
I'm looking at some way to beef mine up. Both of my trucks had the rubber rip where the bolts go through and that was the end of them. I'm thinking about making a sort of U shaped piece to hold the rag joint to the steering shaft so that even if the rubber does rip it will still be connected.
make sure u keep a good eye on those things. my broke when i 4wheelin and i ran into a tree!!
That is what the pins are for, -to provide a steering connection if the rubber fails. If the part was not installed properly or the steering column was not installed properly you can get a failure like that. Make sure the pins engage the holes in the mating plate properly.
They are a catch, but if you catch a rut or log or something then it will pop out. I do agree however than care should be taken as to the installation and inspection of steering components.
If you run into something after the rubber rips frame flex, etc, can pop them loose. They are meant as a fail safe to keep you from hitting something in the first place. If you keep driving after the rubber is gone then you are kinda on your own...
BTW, the "rag joint" is also a vibration isolator to keep road vibration from transmitting to the steering wheel.
they make a shaft to replace the rubber. it's about 250 bux in lmc. They have the couplers in summit to make one. i've been thinking about it long and hard. cause once u run into a tree and bend all the front clip and walk off without a scratch. u start to think what u can do to prevent it!!
***thought*** some old trucks (not sure which- but probably not of ford decent) have the rag joints towards the top while on our fords the are on the bottom. Any mating capabilities?
Hey we can't have any of that mating talk on FTE!!!
U-joints are available at farm supply stores etc. Replacement shafts and even custom parts are available from a variety of aftermarket suppliers. You can find their ads in any 4x4 magazine. The shafts are spendy tho.
