Where do you put differential oil in kodiak 450?

To add differential oil to a Kodiak 450, locate the differential fill plug, which is typically found on the rear differential housing. Remove the fill plug using the appropriate tool and use a funnel to pour in the recommended differential oil until it reaches the fill hole. Ensure the oil level is correct by checking that it slightly overflows when you insert your finger into the hole. Finally, replace the fill plug securely to prevent leaks.
