I have a 1996 XLT SP with XTRA 12 front and back. My problem is that the rear end feels like I'm riding on marbles. On loose snow groomed trails the rear end swisses from side to side. the Fox shocks were rebuilt December 2002. I've played with the front track shock preload and the torchen springs with no results. The rear when compressed only comes up a few inches, but I can pull it by hand about five inches. The ride is still good but the handling s**ks. Any ideas of how to fixs this problem or the correct setting would be great. I'm thinking the torchen springs have worn out!!
