knocking sound when releasing gas pedal Sign In

Hi there,

I noticed today that my car mades a knocking sound only when i release the gas pedal. The knocking sound is following by a slight jerk and then moves a little to the right side. The sound comes around the front right side of the car, maybe around the tire area. I drove the whole day and car was fine, but it suddenly started to happen after i parked for 20 mins. The car seems works fine with no issues driving, but it has got me worried what the issue could be.

If you have any suggession, please let me know. I guess i will have to take it to the mechanic, but wondering if others have experienced such problem or could give me some insight as to what the issue could be.

Thanks for you help.

Worried Driver

I got a suggestion. How about you tell us what the year, make, model, and engine size of your cars is. That might help a little.

Probably the first thing that should be done is a visual inspection with the car in the air. Inspect the steering and suspension components. Pulling front wheels and checking out the brakes and CV axle shafts would be a good idea too. A lot times things going wrong can be seen visually.

Thanks for your help. I took it to the mechanic, and he said the control arm was broken (which controls the stearing and the wheels), and he mentioned that i was insane to drive it since the wheels could have come out at any time. He replaced the right (which was completely broken), and also the left (which was loose and could be damaged sooner or later). Ended up paying $560 bucks to get the car running.
