So last night I was driving my sled( an srx} and basically from a stop up until about 30mph there is a humming noise/vibration that feels like its coming from the footwell area, the best way I can describe it is it sounds like when your riding on pavement. But then like I said once you get up to about 25 or 30 it goes away and seems to run just fine. I looked through old posts and I thought maybe I had a piece of rubber missing from my belt, but I didn't so I put a new one on and didn't make a difference. I looked through the skid and thought maybe I had a bad idler wheel or maybe a wheel was hung up but no luck. Any other ideas what this could be?
 
I would check the drive shaft bearings, esp. the one be the speedo sensor. I had one go bad and it did a lot of damage.
 
Also check the front heatexchanger protectors. I had one on mine come loose last week.

thanks guys you gave me some things to look over on my sled tomorrow. I already checked my slides those are good. 02viper that's funny you mentioned about the front protectors because last year while riding I heard a loud grinding noise and it turned out to be a rivet broke loose and one of my heat exchanger protectors had almost completely broken off and was getting caught in the track. Also last year when I put on a new track we put in new driveshaft bearings. But I also had an incident where I heard a strange sound coming from under the track while riding last year that was more like a bad grinding sound and it turned out to be the chain adjuster bolt had backed almost all the way out, so I'm gonna check that out tomorrow but this time it didn't make that loud sound so hopefully i'll be able to figure this out.
 
well last week when I took it out for the first ride I thought I could smell like a rubber burning smell or like track was too tight and burning up the hyfax. Well the track was a little tight so I loosened it up to this two finger method that my riding buddy always uses, and after that no hyfax smell anymore. And we had gotten some wet snow just before the weekend so I know when I leaned the sled over on its side to check the idler wheels that I saw some ice up in the tunnel but don't think that's the cause of this. Just hoping its something simple and not some reacuring issue.:o|
