I just noticed that when I slow down in AWD there is a grinding sound, seems like it is from the front end. It does not do it in 2wd or while accelerating. I brought to dealer yesterday, and they contacted Polaris and was told it is probably the clutches in the ADC. they said if this was right it would be about $900 in parts. They are going to see if it is possible to just try to make the ADC inoperable by cutting a wire to it to see if this would stop the grinding. I would rather have $1000 then the ADC. Any other suggestions on what it may be or how to fix.
