Need help front end or somthing poping or thud like sound.

[NemesisDP]

Well after spending the day looking all over the front of the truck to try and find what is poping/ thud sound on the passanger side I failed to find it. Checked all steering, cognito, pitman, sleeves, nerf bars, wheel bearings, down pipe, battery, exhaust and out of ideas. Can't make the truck do it over bumps, starting stopping, turning the wheels, driving slow or fast just dose it evey now and then? Any Ideas? Put it in 4x4 and didn't hear it. Could it be in the transfer case? Can fell it on the passagnger side on your feet/ seat.

THANKS

Check the control arm bushings.

Check them again, I was told that they had a problem @ the factory installing them backward's. Other then that, sounds like you checked everything but the motor mount.

I had the same prob when I put on my nerf bars, I don't know if you have some on your ride. But the bracket from the nerf bar was hitting where it mounted to the frame. If you don't have nerf bars, I have no idea what it is if you checked everything else.

Thanks guys I guess I will put it back on the lift and pull off one thing at a time. Nerf bars then one by one check every thing else again. Almost sounds like the cab is poping.

Im haveing a simular problem i get a "POPING" sound when im on the brakes and coming to a stop, and when i leave and squeze the throttle a bit agresivly it pops multiple times. Dose this sound like a ball joint ?

I had a similar problem with my truck and took it to the dealership and they told me it was the body mounts. Under certain conditions, normal movement between the frame and the #1, #2 or #3 body mounts may cause a pop or clunk type noise to occur.
It was a known problem for 2004 -2008 Silverados and they fixed it by installing insulators on the body mounts. This noise can be heard and/or felt at either the driver's or front passenger floor pan area.

Here is another post describing the problem and solution:

I also been having the same type of noise, but I have pretty much all new front suspension and steering parts. The noise only when on uneven road/driveway, never flat ground. But I do have Kodiak drop down steps that mount to the frame with 2 bolts and to the rocker panel with 2 bolts. And after reading that write up from GM and them talking about the floor boards ??. There is a little flex between the cab and frame. Thats the reason for rubber mounts. Has to be the steps and the mounting hardware. I am not sure how or if any one else has the same type or other steps/floor boards.

 

[duckfandan]

Mine "popped" in the floorboard area, you could feel it down by your feet/engine cowl area. After getting the body mount insulators, it never happened again. I did not have any steps, running boards or nerf bars mounted either.

I always thought it was just my steps making the noise as they do rub the frame when it flexes when I turn sharp over uneven ground.

Now I'm thinking it's the body mounts.

 

[NemesisDP]

I guess I will try the cab insulators, see if thats it

Did you ever figure out what was popping

Not sure if this is your first time on a forum, but this being your first post here, did you realize you pulled a 3 year old thread from the archives?
