Alright folks, I have a 97 GTP and when I go to brake with medium to hard it makes a knocking sound. Then after I start moving again I hear the same knock sound. If I accelerate and or brake like a grandma there is no knocking sound. But if I drive normal I hear this knocking sound when I brake and then again when I accelerate. To further describe this sound if I brake (lets say medium hard) it makes the sound but lets say after I have started braking and it made the sound I decide to brake harder, it will knock again. The same goes for when I accelerate.
Today I put it up on the lift and checked everything I could think of and nothing seemed loose or bad except the CV axle, which I thought had some play in it so I replaced it. But with no luck as it still has the same knocking sound. I have in the last year put on KYB struts and mounts all the way around as well as the GM suspension upgrade, along with the HD 12" brake upgrade. And have not had this sound until last week.
I sure would love to hear what you guys think on this. Thanks in advance.
