Last week I was out on my 2012 xf 800 so Ltd. an heard a grinding noise. Kinda sounded like my track was ratcheting. When I hit the throttle it kept getting worse!! Then it turned to a grind.... then a loud grind an then BAM..DEAD!I dunno. Tried to put in reverse another grinding noise, would not go forward or reverse!! Tried to take the belt off an the driven just spun!!! No good. Pissed off, aro:angry:und 1000 miles on it! At dealer now, waiting to hear something.. any thoughts??
