1974 Steering help

Where can I find the coupleing for my steering shaft where it goes into the steering box? Also is there any adjustment for this joint or do you have to replace it when it gets play side to side and up and down in it?

 

You mean the bell coupling? Pretty sure you can get it from the usual Jeep parts places; Turner's, Walcks, etc.

No, no adjustment. It's common that it needs replacing.

 

Remember that the coupling for the power steering gear and the coupling for the manual gear are different.
The shaft coming out of the gear box has different diameters.

 

does any play in shaft usually mean it needs replacing? Also I have the power steering unit.

 

It's supposed to allow axial (lengthwise) movement and some misalignment. It should have no detectable rotational slack.

Note that it's not the only part that wears out. The power steering boxes are known for getting loose over the years. There's also a bushing in the steering shaft (?) that could need replacement. You should look at everything closely. Put the front axle up on jack stands, and have someone turn the steering wheel slowly back and forth while you look.
