i have a O8 Gmc 1500 4x4 ext.cab with 2.5 level and 3 inch body lift on 35s. i have a rattle that happens sum times when i press my gas and sum times not but only when i am moving at slow speeds under 30 mph when i can hear it. i can't find anything loose bolts from my lift but the noise sounds like its coming from my front end to almost middle of my truck. any suggestions would be most helpful because it is truly driving me crazy.

Check your hubs, could also be a bad ball joint. Basically check all your steering / front end suspension parts haha

u-joints?

 

[saucemann]

put the front end on jack stands and push on the wheels by hand to try and find rattle

Could be a heat shield underneath, sway bar links.. Etc

Is it a metal jingling sound?

 

[johnholden]

Yes metal jingle

Mine did the same thing when I ran iroks, I'm gonna assume it was one of the heat shields in my passenger side. Hasn't made that noise sense I removed the iroks
