I need to change the oil in my diffs. how much and what kind should I use?
You need to use 80W-90 Gear Oil, I would recomend getting the gallon size that way you can get a hand-pump that screws onto the top of the bottle. You need to fill it until fluid starts coming out of the fill hole.
The best stuff is made by Cognis for AM GENERAL, 20 bucks a Litre.
1/2 qt per hub, 80W-90 gear oil
Many people use synthetic, like Mobil 1.
2 qt per differential, 80W-90 gear oil
