Sled was not freewheeling down steep slopes and wanted to hold me back.Went to adjust belt deflection seemed a little loose so I tightened it up. Still did not seem right so I cleaned the clutches real good but there seemed to be quite a bit of a metallic powder when I blew out the clutches.I am wondering if I might have a bushing going bad. Sled has just over 2000 miles so I ordered a puller but was looking for any suggestions any help would be appreciated thanks.
