Re: How hard is it to rebuild a rag joint?

Hey my 1st post -

I rebuilt my rag joint using the rebuild kit from Advance Auto HELP section. i used a cutoff wheel to grind the original rivets away and separate the joint. The use the kit to replace the rubber and nre bolts/pins contained in the kit. Very simple - but the joint needs to be removed from the car.

Re: How hard is it to rebuild a rag joint?

Not hard at all, but some will say you shouldn't do it and should replace the whole thing with a new GM coupler/rag joint that has the rivets like the original. If you get the repair kit with the new rubber disc, just make sure you keep the two metal shoulders from the original coupler and reuse them so that you have metal to metal contact when you bolt on the new rubber disc to the coupler.

I did mine last summer, cost about $10 at Napa for the kit which included a new rubber disc, bolts and pins. You'll need to remove the 12-pt bolt (don't remember the size off the top of my head) from the coupler and probably will have to move back the steering column and steering shaft to have enough room to pull the coupler/rag joint off the steering box. Then drill or grind off the rivets on the coupler and put it back together with the new stuff and back in.

Re: How hard is it to rebuild a rag joint?

One last reason to use an OEM flexible coupling. If you find that your horn no longer works after rebuilding your flexible coupling. Here is most likely the reason. The OEM part included a means for electrical conductivity from one side of the flexible couling to the other. There was either a metal strap, a ground wire, or the rubber disc had a metal screen molded into the face.

You will need to provide an alternate electrical ground path. You need to electrically connect your steering column back to a metal part of your instrument cluster or dash.

I simply made a new ground wire for the horn out of 18 gage wire and a couple of ring terminals.

Fwiw, find the kit that has the rubber washer that is tempered steel screen wire re-enforced!!

It is flat stronger AND better than just a cloth re-enforced rubber washer!!

BUT watch the little screen wire ends around the edges b/c they can flat get you!!

I ground mine off using my bench grinder!!

Re: How hard is it to rebuild a rag joint?

Trust me on this. I was the responsible supervisor when Saginaw converted from the ground wires to the molded mesh screen back in the early 1970s.

The wire mesh is just for electrical grounding. It does not add any strength to the laminated rubber/cotton disc. We had many, many durability tests on the flexible coupling. The mesh does not add any durability to the unit.

I don't think that any of the rebuilding kits use a disc with a screen.

Why rebuild when new is not that expensive?

$10 to rebuild versus $50 new. Labor about the same. I'd be broke if I kept replacing everything on my cars with new stuff, besides it feels good to rebuild stuff when you can.
