I hear and feel a hard knock on the floor. It seems like its comming from the front, near the drivers side wheel. The faster I go the quicker the knocks become until I reach about 40MPH then it goes away. I already checked the lugs. I;m thinking suspension but have no idea what it could be.
This is on my 89 Grand Marquis~Can't wait till it stops snowing then I can get my reliable camaro to drive
