Merry Christmas!
I need some comments from the crew...

I have changed all the components except the drag link.
Still have a lot of slop in the steering. Maybe 2" of play as the steering wheel goes back and forth. Driving requires constant correction. BTW, it did the same thing prior to recently installed new tires.

I finally ordered a re-man steering box, BBB brand. It was still sloppy. I returned it and they sent another one. Same result. I have looked and looked and I ~think~ the slop is in the box. Looking under the box and having someone turn the wheel I see the pitman shaft is moving side to side. So I look around the internet and find a guy that says the casting gets wallowed out and stretched. He bores and bushes the hole, then installs a new bearing. Also found the attached information from Cardone. These 2 situations sort of cancel each other...

Not saying I believe either one of these ideas. But it appears that when I turn the steering wheel there is a lag before the pitman shaft turns. And the pitman shaft flexes side to side a little. The re-man boxes are supposedly adjusted to factory specs.

Any comments or ideas on what to do next?

The re-man box is about $85 so not a huge cost, I am thinking I might tear it down and take a look inside(i like to take stuff apart...)

The gear box should have no slop, if the pitman shaft moves laterally, something is wrong and you will never eliminate on center play.This a common problem with reman boxes that are just resealed and basic adjustments done. Even a small of internal play translates into sloppy steering.

This sounds a lot like a rag joint issue.

Have you replaced the joint and/or steering shaft?

I have the same problem. Replaced the steering box, twice, and Pittman arm, the rag coupling and other linkage suspected parts with no change. I was told by this forum that I should not expect perfect steering with a pick up truck. I am still not satisfied with my steering as I have to be on top of it 100 percent of the time which is rather stressful. I am thinking it is just the cheap re-manufactured steering boxes that are the problem but have not got around to spending the money on an OEM steering box. I had a professional mechanic replace the box's and he could not make it any better or explain why it is so screwed up. Hope you find the answer here. I love my truck but do not enjoy driving it the way the steering is.

As mentioned above, the 88-94 factory idler arm is terrible. Even the most expensive NAPA replacements I used in the past get sloppy very quickly.

GM realized this and changed to a much, much better 3 bolt style in 95. There is an adapter now available to convert to the later style here,

https://liftkits4less.com/superlift-2-to-3-bolt -id...

Also, the factory steering shaft between the firewall and steering box is another source of play. Both the upper joint and lower rag joint are not the best design. There is a replacement available from borgeson here;

http://www.borgeson.com/xcart/product.php?producti...

However, their lower joint does not have a pinch bolt and has 2 set screws. I don't care for this design, so I used a length of D shaft, 2 OEM steering joints pulled from a GM Cube Van's shaft and the shaft from the truck's original shaft to build a replacement. Work's really well and no slop.

Be sure that when your steering wheel is centered, that the steering box is truly centered too. Don't trust an alignment shop to verify this.

As for replacement box's, try these guys;

https://www.redheadsteeringgears.com

Never used them, but read many good things about them online. They actually rebuild the box's, not just re-seal and send them out. Not cheap, but not chinese crap.

Thanks for the replies.

Rag joint is replaced, as is idler arm.

Maybe it is the re-man box just having seals and such replaced and the gears set to OEM spec with no accounting for wear as Silverado Kid suggested.

After having checked it multiple times it seems like the issue is in the box. When the steering wheel is turned it is instantly visible at the box input shaft but lagging at the pitman shaft. The re-man boxes come with paint on the adjusting screw so if you fool with that and try to return it I am sure they use that to void the warranty. I may go to the junkyard and pull one to tear down and take a close look. They are having a half off sale so I can get one cheap enough to experiment with.

I will look into Redhead Steering Gears and see what they have to offer.

A steering box will have some play in it. It's not a rack a pinion. I know it's not the way the manual says, but I have tightened the backlash with the screw on top of the box many times with great success and no ill effects. It is worth a try before just sending it back as a core.
