I just changed all the oils and every thing on my brute but i had the hardest trouble finding the recomended rearend oil for my brute. I ended up getting Super Tech Heavy Duty Tracter Hydraulic & Transmission Oil. It stated that it was for wet brakes and had multiple similarity's to what was recommended but i just want to make sure before i Really start riding hard again. I ended up just putting 10w 40 in the front just want to make sure that was fine too!!

 

What you used for the rear end is the correct type.
Couldn't your dealer tell you what to put in? Also, owner's manual tells you what to buy from Mobil, Citgo, Exxon, etc.
For the front end, use synthetic 10-40, instead of the dino juice.
