U-joint vs pot coupler

Just rebuild the pot. A proper pot has no more slop rotationally than a U-joint, and allows for chassis flex, as mentioned.

People will put frame rail connectors in these cars all day long and shout to the heavens about how much of an improvement they feel, then put a u-joint in the steering column (which connects to the frame rail on one end and the unibody/firewall on the other) and act like everything's fine. The frame rails just kinda hang off the front of the car, there's not really any triangulation to the firewall on a stock A-body, and that steering column connects the two.

Or, let me phrase it another way: What do you think is causing that steering pot to wear out? If there's no plunging/axial motion, then the rotational motion between the shoes and coupler housing would be basically zero internally. They wear out because when you're driving down the road, that thing is jamming up n' down inside that pot like a **** star with a short stick. Every braking event, acceleration event, pothole, washboard, etc. etc. is plunging that pot coupler.

Hmmm , interesting point!

Ok , Ive got the pot replaced with a coupler. As soon as I can, I'm going to remove the coupler and the connecting shafts. Then, I'm going to check where the setscrews tighten into the recesses in the shafts. If there is the kind of movement you are suggesting, I should see witness marks where the setscrew is moving up and down the shaft. Also I'll check the bearing for damage or excessive wear,. If I find evidence of that , I'm removing the works and doing the mods shown by 72bluNblu.

Great comments and suggestions guys!
