I bet your friend goes through the mud and muck, or has overside tires and rims with big offset. If your front stabilizer is a shimmy shock or a sway bar end link that sounds like normal wear and tear to me.
Actually no he babys his truck , ,to my knowledge it has never been offroad, it has factory tires & Mags on it , no lift kit , he is meticulous closing on anal about maintainence & just taking care of the truck , he will not even get onto the throttle until the temp guage starts to move , yet at 125,000 he started getting a death wobble in the front end at highway speeds , the front end was bad already & he couldn`t believe it & told me that he had never beat on his truck ever & was very disappointed that he had these problems with so little milage on it
