I have a 1997 Buick LeSabre. For the past couple weeks, I have been hearing a knocking/clunking noise from the front of the car when making slow, sharp turns (Turning around in a driveway, right turns from a stop, etc) or when I am parallel parking. It is not rapid clunking, but just one clunk when turning the wheel and one more when I straighten out. Any guesses what might be wrong? i did have the cradle repaired recently and the suspension is weak, if that matters.
