Hello,
I know this has been covered in the past, but I have not found conclusive answers for what the best, or acceptable, alternative transmission and front differential oils that can be used for 1998 Sportsman 500.
I am using synthetic Chevron Delo 5w-40 in the engine, atf type F in the hubs and currently have dexron III in the transmission. I changed all fluids except front differential when I purchased in May.
I do currently notice a whine when going over 25-30mph in high range or over 15 in low range, but immediately goes away when letting off throttle. I have changed several bearings and u joints and cleaned and greased every location I have found. I am hoping new oil will cure the whine if it is in either the transmission or front diff.
Any help would be greatly appreciated!
Thank you!
Isaiah
