I got a friend at the stealership around here that says he just does the bearing in them even though they dont offer a kit for it. Held up for him so I'm going to give it a try. Updated belt uses the same tensioner for sure. 03 tensioners are for 03 setups only (I think), but some say their all the same. Whats everyone getting for miles on the tensioners? and anyone just doing the bearing? I noticed my belt hitting my belt guard from my tensioner being bad, not helping the life of my belt for sure. I don't see the big deal to upgrade to 04& up setup, I've seen people get upwards of 30,000mi on the original belt. Think it was lucky but like people say, it's all how you treat them, and how big you are!
