| Re: Damage from axel pop out on grizz That oil problem is interesting my local dealer told me to 80 140 on my front diff in my 07 700 grizzly so I wonder if maybe they are talking out there anus. Should I be running 75 90 or 80 90 synthetic in my front and rear diffs and not worry about the thick stuff in the front. The back is okay with 75 90 but now I'm worried about the front: |
