I'm a noob so forgive me if this was posted in the past. I have a 99 Kawasaki Prairie 300 4x4. I was able to find gear case oil for the rear but according to the manual the front requires GL-5 hypoid gear oil for limited slip differential gears. I've tried searching for such an oil but can't find anything that mentions lsd. For my much newer Suzuki Kingquad alot of guys use Mobilfluid 424 hydraulic/transmission fluid in the front. Just wondering if I could use it in my Prairie or if there's a better option? Thanks!!!

 

I used walmart's brand of diff lube on my Praire and still do on my side x side. In my area they carry the GL-5 rated lube in 80-140 wt and bottle says it is rated for limited slip diffs. I do use the synthetic lube. Used it for 10 years without a problem. If you do some research you will find walmart lubes are very highly rated and approved by all car and truck manufacturers as well as marine manufacturers.

 

wow thanks for the heads up. My Walmart had it as well. Quick follow up question. Where's the best spot to drain & fill the front? Thanks again!!!

 

Near the lower bottom half of the diff is a drain bolt, you should see a small metal gasket under the head of the bolt. Then on the upper half of the diff should be a fairly large nut/cap that is used for filling. If my memory is still any good I believe the nut/cap for filling was 15mm wrench?? And the drain bolt was a 12mm ??? Going to be somewhere close to those sizes of wrench. The front diff requires an 80-140 wt lube while the rear calls for an 80-90 wt lube but if you use the synthetic lube you can use the 80-140 in both front and rear diffs.
