specialized bottom shock bolt

Has anybody had a problem with there specialized enduro expert or any full suspension enduro shock bolt? My 2003 enduro bottom shock mount bolt became sloppy about 1 month before my warranty ran out (figures). I took the bike back to the dealer and when he returned it he said that he filed down the spacers on the bottom shock bolt. A month later it was even worse than before, you know, go off a jump, and clunk, there's that noise again! I took it back a few days ago, they removed the bolt wiped it off and put it back together again. The clunk went away for three days and now it's sloppy again. 😠 Two other folks I know have had the same problem as well with their enduro. Anyone? I am begining to think that this is a common problem with this bike. The shop is making me go the long way to get this repaired. I ride every other day and don't have time for this lameness. You can literally see the shock moving around on the bottom bolt mount even if the bolt is snug as it should be!
