Q: Car Clunking Noise

asked by on

Hi there. My car makes a constant clunking noise that only diminishes for a couple seconds during acceleration. It never gets worse. Someone backed into my car and dislodged my bumper, making me think it was an exhaust leak. However, I had an oil change today and the mechanic thought it sounded mechanical, but did not give me any further ideas. Thank you!

My car has 156000 miles.
My car has an automatic transmission.

This is a common noise when the driveline U-joints are bad. Underneath your car there is a driveline that is connect from the transmission to the rear differential. At these connection points there are U-joints that can make this type of a clunk when they have too much play in them. Also, in the rear differential there is something called a ring and pinion gear which turn as the wheels turn and when these also have too much play in them, a similar clunking noise or feel can be experienced. I would recommend having an expert from YourMechanic come to your home to diagnose the noise firsthand for an accurate repair.
