Changing Diff Fluid

[grizzly700fi]

how much fluid is supposed to go in the front and back diff. I know its supposed to be a little below the hole but about how much fluid is that? The front diff is supposed to have 80w-90 but can i put the 75w-90 synthetic in the front?Whats the trick to getting the spare tire to come off i cant get the secondary latch to let go and now i cant get the cable to raise and tighten the tire back up.

75W-90 is fine for both.

quick tip.. loosen your fill plugs first.. it sucks finding out after you drained your diff, that the fill plugs are seized tight and you can't remove them..

another tip..put some anti-seize compound on the plugs before installing them. makes life easier next time..

 

good luck
