Quick question for you guys, last winter towards end of winter I was noticing a scrunching feeling from the rear suspension when I was going at slow speeds on trails, I mean under 15mph, on hard pack snow, I only have full warranty until Oct 31 of this year before the warranty is on the motor only so I wanted to get it looked at, but if anyone else has experienced it and thinks its normal I would not bother, but I didnt notice it at the beginning of the season so I was wondering what to do.

Thanks
 

Was it when the suspension was moving or was it on flat smooth surface?
Did the noise increase then go away with speed?
Could you hear it or did you only feel it? Was it like 40 below that day?
Have you been jumping your sled?
Frozen shock, bent shock rod, bad bearing, track alignment?
Rip that suspension out and have a look. Roll all the wheels and see if you feel any grinding or binding. If I had to guess, I would say a wheel bearing.
I would start by taking out the skid first.

Usual Temps 20 to 32'F, or -6 to +2'C, the sounds goes away with speed, I can only feel it, I can not hear the sound. My brother had his venture to the dealership with a little play in the wheels and they said it was normal, so there is about the same amount of play in mine, I do jump the sled a bit, and do the normal aggressive trail riding, I had checked the alignment of the track and it seemed good. The only thing I can remember is I put a seat jack on the sled and did not adjust the suspension for two ppl, and it was set pretty soft for me, and when me and the woman went riding we bottomed out a fair bit, until we got back and I fixed it, so I am wondering if you can actually bend a shock or something.
 
Is it hard to remove to skid? I do have some experience on the skid some other sleds, but only spent minimal time at the vipers
 
My bud bent his shock rod jumping his polaris.
Have you checked out your chain and gears? A loose chain may be the noise that would go away with speed. Do you feel it in your feet or your butt? Maybe in the chaincase if it is in your feet.
I have no experience with a viper suspension,
but I removed my srx skid several times. It is very easy to do.
When you have the skid out you can check out all moving parts better.

yes plain old ice build up!!Thats what it could be,but i suggest you get into it before the season starts,you don'y want down time.
 
Its funny when you're cruising along and you feel the ice fall off and get between the tunnel and carrier wheels, you can feel it push up from under the seat, lol. I doubt this was because of ice in his case though because he says it is there when sitting but the sound goes away at speed.
 
I have been thinking about it and trying to remember all the characteristics of it from last year, and the biggest thing i can think of that i forgot to mention was that it almost seemed to happen say every rotation of the track, not always there but almost like say, every i could feel something happen say every 10 ft on the trail, like a bad spot of the track or something.

first do a real good check of the suspension, track, chaincase (chain, gears, and bearings) to see if you notice anything visually. Also, try a new drive belt. A notched drive belt can make you think a bearing or something is out because of the vibrations it creates.
 
make sure idler bearings are good as well as all bushings.
if you have not changed oil in the chaincase good time to drop the oil and open her up and check the gears and chain.
Remove the belt and lift the back end of the machine spin the secondary by hand you may feel or hear something binding.
