Knocking sound....

[CarTrader29]

Ok this just recently started to happen. I had this often before when I would hit bumps I think the exhaust pipe was hitting the differential. Went under the car and started shaking the pipe and I was right. Now I recently bent it away from the car but I still hear it. I know its still the exhaust pipe hitting it but some other spot. The weird thing is I just swaped rims and now it almost sounds like the driveshaft is hitting something. The faster I go the faster it knocks. If I hit a bump it goes away and comes back later on. Anyone have any idea what it might be?

Man, that can be anything. You're best bet is to jack it up and take a look. If anything looks too close, it probably is. Look for scratches or scuffs. Or support the whole car with jackstands and put it in gear and drive it in the air. Have someone look underneath while you're doing that.

Yes. It's time for you to take that thing to an exhaust shop and pay them the $50 to get every thing mounted up correctly.
