SUSPENSION NOISES

Has anyone experienced a lound thump coming from around the drivers side or passenger side floor board? It sounds like someone under there with a hammer every time i make a right hard right turn or hit bumps at low speeds or when going over small hills like ant piles or so. Iv'e changed out the bushing on the front & rear traction bars? and i still get that thump when i make the turns. Any one had this problem? I've been under there so mant times pulling and pushing on things and nothing is loose or seems to be moving. other that having a shop take a look at it i'm at a loss.

My wide tires rub A LOT but with your lift I don't think you're in the same boat. Let me know what you find out every once in a while I get a odd sound like you describe but just assumed it was the tires

I FOUND THIS. http://www.frontiernet.net/~jcray/04...50Bushings.pdf this may explain things. I only changed the bushing on the axle & not the others.

My link arm bushings were shot. Every time i'd hit a bump it would "clank". I could grab the link arm and move it. I put new bushings in and now no noise.

I didnt replace the ones on the axle the were in fine condition.

if the sway bar links are touching the frame it will make noise. The bolts have rubber between them and the link. Then the link has rubber between it and the frame. The rubber likes to push away from the frame resting the link on it. Every turn metal hits metal. Also the trac bar bolts need to be real tight. If those 2 dont get it, I also had to put rubber between the leafs on the front. The leafs(2 pieces per side on mine, not 3 or 4layers just 2) needed to be spread apart and greased. In my case i used a piece from a hard rubber from a floor matt with grease on it to seperate them. If this does not make sense pm me

I got under there again yesterday, i'm down to thinking either they gave me the wrong bushing for the sway bar. or my leaf springs are moving where the bolts goes thru the rounded ends. Now i'm not positive but it looked like some rubber was hainging out of that area. I'm just going to have to get it in the air and have a better look see. Its a lound thump. so its gotta be one of those 2 things

I THOUGHT about taking it off, to see if that where it was coming from. Still might, A process of elimination i guess. I talked to a couple of guys that had the smae problem 1 of the 2 took his to the shop sohe didn't know what it was. The other is like me still fighting with it

I'm having the same issue on the drivers side! When I go off curbs or turn hard etc..

But I think it's also because for some reason my frame and body are separated on the drivers front side :wtf: Look at my threads I've made.. i took pictures too. There is a 2" gap between the frame and body on the front left, after making a recovery of a stuck dodge this happened. My bumper hangs down lower too as it's attached to the frame
