I have a rattle sound when I first start off...either in forward or reverse. It sounds to be coming from under the truck...Please give me suggestions...I can't stand it.

 

if you have duals check your clamps. one of mine broke off and took it to get it fixed this morning.

 

i actually had a rattle too, come to find out when i did my plug wires, i routed them around my tranny dipstick tube and it was hitting my valve cover/intake. re-routed wires underneath the tube and its gone

 

Exhaust clamps. Check them.

 

mine had one and it was the heat sheild by the cat

 

go tap the cat with a rubber hammer an see if you hear it. if not tap around down there

 

Isn' t that going to loosen stuff up in there? SO if I hit it and it rattles..then what?

 

either live with it, replace it, or gut it.

 

then you found your rattle







then you can deside if it's heat sheld or it's in side of the cat.
if it out side (heat sheld) weld or punch it
inside, new cat, gutt the cat, or y pipe

it very common on these ram truck to have a bad cat
