The driver's side I believe is a pressed in aluminum bushing. It defnitely didn't have any rust like a steel one would when I rebuilt both of mine.

Hi Tony - wrong side! 
I thought there was someone that had modelled the whole rack, was hoping he'd see this and chime in.
Bushing was for sure not aluminum. Totally looked, felt, and weighed about what powdered metal would be.
Was stupid busy at work and didn't get a chance to call around to find some material. Hopefully tomorrow so I can get it done over the long.

I'd be inclined to think that the issue would be with the bearings for the input shaft since it seems to be on the left side. It's common for them to deteriorate from what I've heard.... Rodney Dickman sells them, they're pretty cheap and they go in easy; I replaced them when I overhauled my suspension a few years ago. https://rodneydickman.com/p...php?products_id=370. If everything looks good suspension wise like you're saying it is, I'd rebuild the rack with some new bearings and a bunch of high quality grease as well as the brass bushing on the right side... Though it couldn't hurt to replace the ball joints and tie rods while everything is apart. Low miles or not I'd do it anyway due to age, honestly! ------------------

You said the ID of the original one was 23.25mm. What's the ID of the one you fabricated?
How did you get the original one out?
I remember mine had a lot of clearance between the rack and that bushing but neither makes any noise like you describe and the steering is like new.

OD of the rack itself is 21.96-22.00, so I made xxx.
There's a small clearance area on the inside, just (!) big enough to get a hook behind.
Heated the rack end to let it swell, and with a slide hammer got it out. There are inside bearing pullers that would have worked better, but I don't have anything the right size/shape.
-
There isn't enough (built in slop?) to let the input pinion go back in correctly. I'm going to have to sneak up on it to find the happy spot.
Sure be nice if someone with a good working rack had taken these measurements... sigh...
A sample size of ONE does not good data make! Heh.[This message has been edited by watts (edited 05-24-2021).]

Nice work! Wish I could fabricate... well, anything.

As well as a 2 years of Bonneville.
I'm sure someone's tested THAT theory over the years! |

First time I've ever heard that!
But wouldn't that be a b!tch, after all these years?
Edit - Of course I had to check. Obviously a mistake. W-body has the rack behind the wheels. Turns the wrong way.[This message has been edited by Raydar (edited 05-24-2021).]

I know you probably didn't measure it, but... do you think it was actually ~1.5mm ?!
If it was that much, it just seems nuts as it wouldn't actually contact anything.
