Martin466 0 Report post Posted June 9, 2019 Anyone have an idea what this knocking sound would be? It doesn’t happen all the timE. It occurs when I apply the brakes and slow down. I just recently had my brakes and rotors changed a week ago. I’m not sure if that has anything to do with it or not. I just had my control arm replaced and it’s still doing it. If you guys have any suggestions or thoughts I would appreciate them. Quote Share this post Link to post Share on other sites

Can you be more specific about the type of noise? Is it only under heavy braking? Quote Share this post Link to post Share on other sites
bskies4 0 Report post Posted June 26, 2019 My Infiniti M37 knocks when I slow down, go over a bump, or turn my wheel. I was told my control arm needs to be replaced by an outside mechanic (not Infiniti) and we just had my car in for an oil change with Infiniti and they told us we need our steering rack need to be replaced. I didn't tell them what the other mechanic recommended. I wanted to see if they would come up with the same diagnosis. Now I don't know which one to believe. I was told over and over when I took my car to the Infiniti dealer that "This is our best mechanic and they really know what they are doing" This was after bringing my car in three times to figure out why may car was making a grinding sound after my brakes were replaced. It ended up being my rotors. They had already turned them and shouldn't have turned them again when they replaced my brakes. Anyway, they fixed the problem, but I would think Infiniti mechanics should really know these cars, and it shouldn't take three visits to figure out a problem Quote Share this post Link to post Share on other sites
James Willilam 0 Report post Posted March 6, 2020 When the mixture of fuel and air inside the car cylinder is not functioning properly, the fuel cannot burn evenly. Types of knocking • Car knock • Spark knock • Skirt knock Following are the points that help you to recognize the knocking noise issues • Low octane rating fuel • Wrong spark plug • Carbon deposits This issue is solved by an expert mechanic. Don’t worry; just take your vehicle to your near mechanic shop. Quote Share this post Link to post Share on other sites
