95 King Quad front diff?

[raythomas]

Can someone tell me what type of oil / grease goes in the front differential of my 95 king quad 300?

And also, how often should it be changed?

Thanks

It uses 90 grade gear oil.. as used in car diffs and gearboxes. I don't know what the changing schedule is but that will be in the manual.. Mostly it never gets changed.. If you go through deep water, really deep, then take the filler bung out and see if the oil is milky with water.. change it if it's got water or metal dust or flakes in it.

Ok.. The manual says to change the oil every year. That will probably only be to guard against condensation getting in the oil.

Looks like I'm about to buy some gear oil 😊

Thanks for the info.

I forgot to ask before but, is this gear oil "standard" 90 weight? Reason I ask is I owned a yamaha grizzly one time and it said it needed special "hypoid" gear oil.

Dumb question, but would it be okay to use 90 weight hypoid grease in my 95 model King Quad front end?  I don't won't to put something in it that I shouldn't.

Thanks

Yes it is hypoid gear oil.. 90 grade is the viscosity.

I don't think there is any such thing as hypoid grease, and if there was, it's number rating would be something like ... oh.. I don't know.. perhaps 2000

When i think of differential gear oil, id think 75-90  or 80-90 gear oil.   not sure ive seen a straight 90.    not sure id use a grease in there.  that doesnt sound right.
