I just got back from michigan this week. This was the first time I have been riding this winter. I just put a new 1'' Hacksaw on my '00 srx this year. When I am going through slower areas at 20 to 30 mph Ihave a strange howling vibration by my feet. Could this be from the slightly larger lug track? My shocks are shot and need to be rebuilt, could this be a problem? When I put the new track in I put a new bearing in on the clutch side of the drive shaft and the other one seemed to be fine. Does any body have any ideas?
