Got o/r prochamber installed.....now there is a rattle/vibration in first gear under 2500 rpm. I can feel it through the floorboards and in my right foot. Its most noticable when the wheels are slightly turned. Its only down low and I cant see anything touching from underneath....but IDK. Can someone give me some advice?

 

When does it happen? Accelerating, decelerating, coasting down, cruising at a constant speed? Does it only happen in first gear?

 

Its most noticable in first gear while the wheels are turned left.....its almost like I can feel something vibrating/rattling on the floor boards....I can hear it too. Its only down low though.

 

do you have enough clearence? bolts tight?

 

I would check and make sure you tightened everything up again! also check your midpipe hangers(since you have an 06) to make sure one of them didnt pop out. I had that same problem on my 07 and it was the midpipe hanger that wasnt all the way in place!

 

Oh yeah, check the metal hangers for the mid pipe. The part that attaches to the transmission cross member is a rubber hanger, but has a metal surrounding. If the metal surrounding is making contact with the metal hanger welded to the exhaust, then you have a rattle.

 

Its not really a metalic rattle....its weird.

 

It is hard to get an idea for what it might be through your explanation. Can you get a sound clip off your cell phone or movie camera?
