Hey, guy's have you ever tore one apart to see whats the problem. I got a buddy that has a 99 with the other mirrors and some one give him a set of the tow type mirrors, but one was real loose. We figured it had to be something simple causing all the failure right. Well, this is what we found out. First of all you have to bust the mirror out, and behind it is a stud with a star shaped keeper on it that puts pressure against a Teflon looking half of a ball like thing, and it sets against the part that holds the mirror which allows it to swivel. What I done was, I pulled the keeper out and the ball thing. I took some rough sandpaper and rough the ball backing up, and the inner socket that the ball sets in. Next take the keeper and slightly bend the ears that press against the stud, which sticks through the center that holds it all together. I then assembled all the parts back in reverse order using a large socket to tap the star shaped keeper down onto the plastic stud. I carefully tapped on it until there was enough pressure to tighten the mirrors swivel carrier. I then stopped by the local glass shop and picked up a mirror and glued it back in place. The mirror cost me 15. 00, Hope this helps anyone that is out of warranty, and using cardboard wedges. It worked for me and is actually tighter than the other one. Eric
