I am experiencing a grinding noise when I slow down on my 07 800 X2. I submerged it about a year ago, and changed the tranny fluid with the polaris brand stuff and the oil multiple times and the front drive fluid. I did NOT change the ADC fluid or the rear drive fluid as I could not find but one drain plug in the rear or one fill plug either and that was the tranny.
Not sure if it is the ADC or the rear drive, but it sounds like it is coming from the front. I also read on a thread that Polaris was having problems with the pumpkin something or other? I would like to change the ADC fluid and the rear gear box fluid first before I do anything else.
HELP.

 

if you still have your owners manual it should tell you how to change fluid on the front housing. there is a drain plug on bottom and a filler plug on the side. the issue w/ the awd is that some people are having cage breakage issues. if you have got water in the front housing or any other part of the bike fluids, you should not be running it until the water is out as it could cause damage to parts. imo

 

Thanks for the advice. I was in the Polaris shop that I bought mine at, my son was picking up his new motorcycle. I looked under an 800 and sure enough I could find the drain plug. Mine must be hidden by the skid plate though. I still do not see a filler place on mine. I will check better Sunday or Monday.
