I could be off here, but Troopers have timing belts, not chains. My 93 Trooper has a timing belt and was changed around 60k. I am preparing to have it done again now that I am almost at 120k, like the manual says. (i have the 3.2 dohc)

If you were quoted $800 just to do the belt, that sounds really high. I was quoted just under $900 for a complete 120k service (including belt, tensioner, water pump and a bunch of other junk).

If anyone else has better info, please chime in... <img src="/forums/images/graemlins/confused.gif" alt="" />
