Not happy with ride of 07 denali, what should I do?

[BEEMDUB]

Alright so I'll start telling you guys about what I don't like, and then what I know is wrong..

1. The steering feels loose and sloppy as hell, the steering wheel has WAY to much play in it and its very unpleasant especially when going over bumps
2. The ride is way to rough when going over rough patches in the road, it feels like the trucks going to break in half

What I know is wrong..

1. I know that the rear air shocks are blown, I would just assume the fronts are ripped too, I NEVER hear the compressor, which makes me lean to believe that its done for as well. I was contemplating ditching the air ride and just replacing with the monroe conversion kit. I never tow

Since you know the shocks need replaced I'd, obviously, start there. I'd also give things like the ball joints and tie rods and things of that nature a real close look to see if any of those things should be replaced. A check I would do is lift up the front on jack stands and see if there is any play in the wheels either up and down (one hand on top of wheel and one hand on bottom) or from side to side.

Got it I'll check the joints today then, would you happen to know how to adjust the steering gear box? I read several threads where guys were saying they corrected they're sloppy steering wheel by adjust the steering gear box

I haven't got the foggiest idea on that

Also check the ISS(Intermediate Steering Shaft). Plenty of threads about it-basically the grease in the shaft all settles to one place and doesn't cover the whole thing like it should. Steering feels over exaggerated and loose-bumps also feel worse.
If you are gonna ditch the air ride don't forget to get a module to fool the computer or else you will have a warning light on the dash.

^^^good advice

Steering on a 07 is a rack not. Box. The bushings go bad. It's actually just a bad design. I'm on my 4th rack. They are crap. Don't get the rebuild get the actual new one.

You can redo pretty much of the complete suspension front and rear for a lil over 2 grand. That includes ball joints arms rods ect....

You have no gear box.... its a rack and pinion.

Pull the boots back and check for PS fluid.

Any at all and you have a problem.

Thanks guys, I'm in Chicago now, I'll be back home tomorrow night, I'll check out the steering shaft Tuesday. As for the suspension I kinda of just want to say screw the autoride, I know the rears are blown, what am I checking in th front to see if they're done too? Also what is the best cost efficient but still quality kit to replace my shocks and possibly my front struts too?

Did you ever get it fixed. Wondering what you did as my truck is acting similar.

I'm looking at this on my 07 as well. The only original suspension up front are the inner tie rod ends and the lower control arm bushings. Everything else is new and I still feel the sloppy steering over uneven roads.

I've looked at a couple of my other vehicles with a steering rack and they don't have bushings at the mounting points like these trucks do. Even my STS appears to be a solid mounting point and that isn't harsh through the steering wheel.

In the spring I'm going to look at maybe finding a replacement bushing that might fit, maybe there's a control arm bushing out there that would be the right size to press in. Either that or maybe a solid piece of machined steel/aluminum to press in to eliminate the rubber and see how that works.
