Sound coming from the front end???

[usmcman001]

My 3 recently started having a creaking noise in the front end when you turn left or right. Hard to explain but its loud. You can feel it in the floor board and is on both sides. When driving straight it does not do it. It is really bad when turning and hitting a bump or something. It keeps getting louder and I cant find where its coming from. Any ideas guys. I thought it was because the weather is getting colder here in nc...Any comment....

Check the body mounts. I heard similar noises/clunks in my 07 when turning and turns out the left front body mount wasn't torqued right at the factory. The e-brake cable was also wedged between the body and frame, which was part of the problem. I was at a loss, but the dealer found it and fixed it right up ... no more noises

Have you had the front shocks checked?

I have the same thing. does it sound like metal bending and then popping back. I was thinking it was the torsion bars working or something, but people keep mentioning body mounts and I think that may be it.

[usmcman001]

Its sounds exactly like that...I am getting it check as soon as I can. I is pissing me off to no end now. The woman is sick of me b*****n about it...Ill let you guys know...

[kma]

Please do post if you get a good diagnosis on the problem. Ive had it since day 1, and its the only thing I dont like about my 3. well, that and all the flat tires with the wranglers.

Same as the H2.

They told me for weeks it was because of my undercage being bent up into my exhaust. I removed it, but the sound was still there.

It took them another few weeks to realize that it was the body mounts.

I gave the ones Timgco found behind me on Golden Crack in Moab. " Hey Dennis, I think this fell off your rig. WTF is it?"



Check your body mounts up front. Gewd ruck.

Ok, I FINALLY got my H3 to the Lubbock dealership yesterday. The Hummer service guy that I usually deal with was there this time (he was not there the last time I took it in for this popping noise problem). I explained to him what the problem was and he said he would like to drive it so that he could hear and feel the problem. When we got back I told him that I had been explaining my problem on this forum and that several people said that it was the body mounts and I asked him to "PLEASE" have them checked just to be sure. He gave me a loaner car and I left...around noon he called and told me that "IT WAS THE FRONT BODY MOUNTS"!!! He mentioned something about "lubing them but the problem would just come back again, so we have ordered them and are going to replace them". My 2 middle AC/Heater vents were also broke so he is going to replace those as well. He said that it would probably take a couple of days to get the parts here and installed so I am driving around a white Impala (yeah, wish I could have got an H3 instead) until then. I will post the rest of the results as soon as I get them.

I lent my 3 to my brother and when I got it back it was making a weird noise. I felt like it would pop whenever the back wheels went over a bump(Speed bump, or uneaven road) and turning also.
However you guys are saying urs all stems from the frontend.
It sucks cause I feel like a wheel is going to pop-off, Im getting really nervous.

Next week I get out of school, and then I have to take it to the dealer.
on a positive note, do u think the dealer would give me an h2 loaner? I want to destroy a 2

Just got mine from the stealer, could not duplicate..
It's a Hummer thing, so there you go.

[TexasRTR78]

I just got back from Lubbock with my H3....they fixed the air vents and replaced the front body mounts...the service guy said that the front body mounts were "improperly installed" and that is was caused them to fail...anyway, I didn't really get any more info than that.

I tested it out on the way home and no more popping/grinding sound!!!

Just wanted to post this in case anyone else has this problem...my service guy said that they have not had any other cases like this ohter than mine...hope my problem is fixed for good.

Have a friendly garage raise your hummer. Gently rock the hummer side ways..
the mechanic can now easily feel his way around under the hummer to feel where the sound is comig from.

A guess:

It is probly a loose suspension component. I had the same problem . In my case it was a loose stabilizer bar (also called sway bar). tightening the nuts will solve the problem. You will need a power tool to do this. Try to do it according to spec if possible.

I know this sounds crazy, but mine was making a similar noice and it ended up being the left upfront rubber grommet that the hood sits on.. I just turned it down two turns and the noice went away.. I heard the noice when I would turn at low speeds and when going over bumps.... It was driving me nuts... Sounded like something was crackling in the suspension..

I have had a similar issue. Sometimes there would be (and still is as the issue isn't resolved) a popping noise coming from the steering column, but sounded like it was under the hood rather than in the truck. It was especially noticeable when turning at slow speeds, and going over any sort of uneven surface made it only that much worse. In warmer weather it's really apparent, especially in slower city-driving conditions.

The techs at Sewell here in Dallas have shown me the problem, and have tried to fix it by, on one visit by replacing the upper intermediate steering shaft, and once by rotating and tightening the bolt that connect the upper and lower shafts.

What I'm hearing is the shaft flexing and popping under stress. After the second visit to the service dept. I thought things were fixed for good. But, the noise has just come back now...a little over a month later.

I watched the tech reach up under the hood and grab on the upper and lower shaft to show me how any stress on it made the popping noise.

I told him thanks for recreating it...now make it go away.

So I'm about to take it in again, as soon as I have some time.

Anyway, this could be what you're hearing.

Mine has been in the shop for the third time for this same problem. They have called GM in Detroit and they are saying it is characteristic of the H3 to do this. Certain driving conditions make it happen. I am not real happy with that but from what it sounds like it's doing it on most of the H3.

[GotSandH3]

It sounds like it might be a torsion bar problem. I work for MBZ and the ML's have the same problem. There is a plastic bushing that supports the torsion bar keys. When the plastic cracks, it makes the same type of noise. I dont know if GM torsions are built the same way but it might be something to look into.

Open the hood look at the firewall. There are some long skinny steel black tubes (I am not sure what they are for) they run the length of the firewall.

They are not far down almost at the top. These tubes are put in on little plastic cheesy mounts. They can easily pop out and luckily easily pop back in. Because of their location they sound horrible when you hit bumps (if loose). Check these out and make sure they are secure.
