I have a 00 335. Just had a new tranny put in doing good except when going down bumpy hills I notice a noise coming from what sounds like rear cv/joints or u/joints. I only hear it wile going down hills with a lot of bumps in it. Has anyone noticed this noise with theirs I have 10 hrs on the bike now and didnt notice this noise the first time I rode prob. because i was listning to the noise in the tranny. Is this normal or should I take it back in to the dealer. I have been told the brakes will make a noise under normal use, could this be the culprit. Thanks for any info.

 

It's either the rear shocks fully extending(out of travel) or the brakes starting to lock up.
You only hear it when going downhill because the weight transfers forward.
When the brakes start to lock up, Wheels lock, unlock etc., the load on the transmission mounted rotor makes some noise. It's hard to describe.
Also when going down rocky/bumpy hills, the shocks will fully extend and make noise when the shocks run out of travel.
Being that your transmission was just put in, check all mounting bolts just to be sure.

 

It only does it when in gear. Tried to get it do do it in netural quiet as a mouse. Any Comments

 

Now that's odd. Wouldn't think it was something mecanical, being it only does it going downhill. Sounds like something is loose to me. Double check all bolts,caliper mounting,rear rotor,shocks mounts,etc.

 

Checked everything all tight. I did notice some slack in the tranny. Asked some other polaris owners if theirs made the noise they said yes. I guess its normal.Thanks for the info.
