As it turns out I didn't get the alignment or wheels balanced as my idler arm is shot, so will be getting everything done after I've had the idler arm replaced <HR></BLOCKQUOTE>Same thing happened when I went to get my alignment done.

I got mine done under warranty, and when it was done, the tech told me I need to start brining my truck to them for the Oil Changes if I wanted this to be covered under warranty from now on.

Reason being, is that the Idler Arms, etc, are Greasable joints, and they were bone dry. Since they are under the skid place, most places like Jiffy Lube or whatever, won't mess with them.

He's positive that the fact that they hadn't been greased, and the amount of time I spend in the water is what caused their early demise.

"...know when to hold'em, know when to fold'em."

I can say that I am getting better at that, in terms of the H2 anyway.

Anyone else have torsion bar adjustment bolts adjusted so differently. My passenger side is adjusted all the way up and the driver's side is adjusted all the way out (or, if even possible, backed out)

Funny enough, I was just thinking about torsion bars, as I get my truck back tomorrow, hopefully with a new idler arm. I mentioned the lean to them and they also replaced the right hand rear coil, which had taken a set at some point.

I also got the fuel filter, air filter changed, throttle body cleaned, and some other service stuff done.

Hope they solve your banging sound out, and keep us informed. <HR></BLOCKQUOTE>I need to clean my throttle body also, my truck is sounding like is has a high lobed cam when idling sometimes. My Denali does the same thing and I have used "Carb Cleaner" on it after the tech at the GMC dealership told me that's all he does.

Well, I am currently in a Tahoe. Will see what they come up with.

Paragon,

I recieved my truck back from the dealer yesterday and they replaced the idler and pitman arms under warranty no questions. The tech said that this is common on any truck that is wheeled much.

They didn't have time to get to the rattle unless I left it longer and they thought it could be the supension components that they replaced. I needed the truck back so I told them that if it contiues to rattle I will bring it back at the next oil change.

It is still rattling . Have they fixed this with yours?

The banging had nothing to do with the suspension. It was associated with the TSB Klaus posted here: http://elcova.com/groupee/forums?a=tpc&s=2826088551&f=6706011751&m=381104074 &r=673104284#673104284

It's the first TSB Klaus posted. I picked it up and was driving down the highway and the noise was worse, so I turned around and went back. The tech and I then rode down the street and he heard again. We get back and he shows me what it is. On the driver's side there is inner sheet metal and outer sheet metal making up the fender where the battery is. The TSB says to dimple the inner fender and he did that but it made it worse. There is a hole on the outer panel that he also had to "dimple".

Heard back from the dealer this a.m. They are going to replace the torsion bars but of course have to order them. Won't be in until next week.

Service tech said will be OK to take out this weekend on the Happening and shouldn't have any troubles. He can't find that they are affecting anything but are definitely not right with the adjustment bolts adjusted so far differently.

Also fixed the cowling around the windshield to stop the wind noise from there.

I spoke to the service rep (not service tech) and he said they were almost done but didn't think it would be done today and I am to come pick it up on Monday.

Asked about the banging sound in the left front end. The rep said that there was a bulletin on that. Klaus do you know of a bulletin for a "popping sound from the left front?"

If your went to the dealer a checked some other H2's, you would find they are all different. Some have the driver's side cranked up more and others may have the passenager's side cranked more. The dealer should be able to adjust the "Z" height to stock specs and do required realignment. Anytime time the torsion bars are adjusted the alignment can move out of specs.

I cranked my torsion bars up to increase front end height and get away from the raked look that most GM trucks tend to have. Since I have the standard rear suspension, no adjusting rear air bags, this worked. The ride is a little firmer, but better overall.

You know, Hummer QC is at best questionable. I have seen more than a few instances where things were BROKEN during install at the factory and never fixed. Now be it nothing along the lines of the magnitude of a bad torsion bar, but issues all the same. I got a survey in the mail this week from Hummer and I will certainly outline these issues.

Paragon,

We have a H2 tech here that is very good and I took a long ride with him this morning to demonstrate the noise. He heard the noise but didn't offer any explanation as to what it might be. If there is a bulletin that would be helpful.

As far as the idler/pitman arm goes he says that this is normal for almost any H2 that is off roaded much. I am not sure that I like that explanation and I don't want to be replacing them every 6 months. Have you heard of any heavy duty aftermarket replacements?

I am supposed to pick up the truck tonight but they haven't called me as of yet.

Since my illness still plagues me I haven't and don't plan to do a tremendous amount of off-roading. I bought an extra set of wheels several months back to get a set of 37's mounted on. Now I wish I had since we decided to do the Hummer Happening here this weekend:

Hummer Happening / Red Creek Offroad Park

Tech said that my right torsion bar was very weak and that had him more concerned than the left one (the one with the bolt hanging down).

Replaced the right one, set the ride height and re-aligned it. Now both bolts are roughly the same. Tech said that before it seemed my front was sitting lower than it should be so he had the bolts adjusted a little higher so that it is more even front to back (no rake).

David,

I haven't been able to narrow it down. I can go over a bump go back and go over it again and it will do it the first time but not the second. You described exactly what I hear/feel but it doesn't do it consistently in any driving situation except for bumps. It is like if the front end gets light from coming off a bump is when it does it the most, but I can't be sure of that. The tech jacked it up this weekend at a Hummer Happening and he could find anything loose or noticably bumping.

Other than the noise/feel you don't notice it. There is no pulling, no unlevel stance, steering is the same, etc.

I'll post here as soon as I know more so you can tell you dealer what to look for.
