pop noise

[Joe Merchak]

Hi guys

I searched but could not find anything. I have this issue with my 2018 Express 4x4 with hemi. When I drive slow I get this popping noise from the rear of the truck. You dont hear it at driving speed and the truck does not drive any different. It happens in forward and reverse and does not take a large bump to make it happen. I can make the noise happen by pushing up and down on the top of the rear door opening of the cab and rocking the truck. The noise is around the rear wheels so I am thinking its in the suspension so I check everything while resting on ground and nothing is loose. I do have timber grove airbags and copper discovery at3 xlt tires but with the air bags filed or not the noise is there. I am out of the 3x36 warranty so dont really want to go to the dealer until I have some idea what could be the matter.

Any ideas?

Thanks
Joe

Have someone push down on it while you lie under to hear and or feel for it . Maybe touch the coil springs to check for movement.

Something for you to check, I had a noise the least little bump I'd hit, literally sounded like something was going to fall off. Both of my shocks were just loose enough on the bottom mounting bolts just enough to not squeeze them tight. Sound as quiet as a new truck just doing that. My top ones was tight but I'd check those too, wouldn't hurt. Just something free to try.

Thanks I will. Just sucks, its only going to be a high oh 20 tomorrow and 27 on Sunday. Not fun laying on the cold driveway when its that cold. Sucks my truck wont fit in my garage, it sits too high

You must be down in south jersey, we’re only going up to 20f tomorrow in far north jersey.

Nope Warren County, I did say 20 tomorrow but I put oh instead of "of"

Yeah, come on down to South Jersey this morning. We're having a heat wave. It's a balmy 13° right now.

So I took it to my local mechanic and he checked it over and he finds nothing in the suspension, cab mounts or frame that is wrong or could cause the noise. He even checked all the heat shields and they were fine. This sucks...
