The truck is a 2001 XL Denali. It runs pretty smooth at all speeds, but when it comes parking the truck or turning the wheels to the left or right......it does a gear-clicking-jumping-shaking sound from the front wheels. I don't if there's a drive shaft problem or transmission problem or axel problem?.....How can a troubleshoot the problem?........please advice. Thank you.
