Polaris Sportsman 500 ATV noise question
Ok all you ATV folks out there. We recently (March) picked up our very first ATVs. Used, of course. One is a '98 Polaris 500 Sportsman. Runs fantastic- we've had them everywhere already and they run great and are very dependable.
My question is, somewhere (can't pinpoint it) underneath, front end/tranny I don't know, when we let it coast like going down a steep hill, it emits a loud screechy type whine. Is it wheel bearings or tranny? Or possibly something else? When we accelerate again it stops. So it seems like a transmission thingy.
My concern is its too loud and can be heard from some distance and its not so quiet. The muffler is pretty quiet, but this screechy thing has me stumped. What to do about it- is it common, is it a sign of near future repairs?
Other than that whine, it runs great. Suggestions? Oh yeah, it has 4600 miles on it.
