If you are towing your rig with a ’99-’06 General Motors truck, or a Chevy or GMC vehicle, there’s a good chance you have experienced a strange clunking noise when making slow turns.

If you have encountered this problem, it’s not your imagination, as there appears to be a unique conundrum associated with Chevy and GMC pickups, and their corresponding SUVs.
