Hello, I own a 90 Shelby Daytona with the 2.5 T1 motor and auto trans. I've owned this car for 7-8 yrs and it's always had this issue. During moderate and harder acceleration it feels and sounds like something under the front end is thumping. It not a clicking sound like when cv joints go bad. Nothing underneath is loose that I have ever been able to find. Anybody have any ideas? Tia for any replies.
