The shaft on my car (Top) is worn out and need to be replace or rebuild. My question is an upgrade shaft available to improve steering.

 

How is the shaft worn out?

 

The boot is ripped and I've never touched it since I had the car. Are bearings inside that coupler? I wasn't sure if it affects the feel of steering?

 

Do you mean this? Upper or lower?

 

The bottom image sir.

 

The seal can be replaced. There is not much inside of that. The clip holds it together.

 

If I'm not mistaken you can buy a new boot for the joint. Its like a CV joint. Remove the clip to remove boot then clean it out and repack with grease. Install new boot and good to go unless there is severe damage found inside.

 

Oh ok, not much to that at all. I'll look for the boot so I can repack and replace. Thanks fuys

 

Look at the Chevelle sites for the steering shaft parts - it's the same shaft in that year A bodies. Just clean it up and re-grease it. IIRC, need to press out the cross pin in order to get the boot off. Been a few years since I rebuilt mine.
A new ragjoint will do much more for improving steering feel, but nothing can help a steering gear that is sloppy.

 

I've changed the gear box with the GJC gearbox but it's leaking and I'm going to replace it. I replaced the rag joint as well. I bought the kit from Lee Engineering.

 

I think you can take the rag joint bracket off and slide the rubber seal down the shaft.

 

I'm curious why you think changing what is essentially a solid metal shaft can "improve" steering.

(Yes, I know it telescopes and has a u-joint at one end)

 

It was just a thought. My car handles good. Maybe my standards are a little too high..lol I blame it on these new cars these days.

 

Actually it does not telescope its got shear pins in it in case of an accident to allow it to collapse. Sorry Alex as much as you try it won't feel like rack and pinion.

 

The boot is not that easy to replace as everyone seems to think.

 

There are a number of things you can do to an A-body to improve steering response. Changing the steering shaft isn't one of them. ASSUMING all steering parts are in good shape and not worn, the easiest thing to do is to crank in as much positive caster as possible with the stock suspension design. When new, these cars had zero or slightly negative caster. This made steering easy (especially with manual steering) but hurt stability and steering feel. This caster angle is one of the big differences in newer cars. Of course a quick ratio box will also be a big improvement.
