You may have excess play in the steering box. There is an adjustment screw with a lock nut on top of the steering box. Some slack can be removed by adjusting it.

Ah, now that helped. When you have a lift, usually it will get a little bit of play not matter what, but what I did with my 1977 Chevy/GMC pickup that I had, is I bought a stabilizer bar / strut / shock (whatever you want to call it) and sway bars for the front and rear. I decided to try the sway bars and never even put on the stabilizer. You can pickup a nice set of sway bars for under $200 and they HELP. Trust me, I went through the same thing with this set-up :

1977 GMC Sierra Grande 15
6" Sus. Lift
35" Swampers
16" white powder wheels (no-name cheapies )
Detroit Locker in the rear up to 3.56s
Custom built Drive shaft

How about that Rubber "coupling" between the gear box and firewall?? Mine had small tears on bolt holes on an 86 chevy and it had alot of freeplay.

Make sure your frame is not cracked where the steering box mounts.

loose steering

the frame is solid no cracks, the rubber spacer in good shape, so a sway bar would improve the looseness of the steering? is it still possible it could be a bad steering box?

thanks fellas for the help. ill get to the bottom of this soon enough.

Well I would suggest you crawl under the truck and have somebody crank the steering back and forth, and see where the "slop" is. That was the only way I found the problem with the Pittman arm ...everything looked fine, but the joint on the end of the Pittman arm was ready to come off! Good Luck! ...Mark
