Which gear oil is best for a 14 bolt axle?
Wondering which gear oil is best for your 14 bolt axle? You’re not alone – it’s a common question, and the answers you’ll find online are all over the map. Many people recommend 80W-90 or 75W-90, but we have found that the best gear oil for the 14 bolt axle is 75W-140.
How much oil do you put in a 14 bolt differential?
The gear oil capacity of a 14 bolt axle is either 3.6 quarts (full float) or 2.75 quarts (semi-float). However, when it’s time to fill the axle, don’t try and measure out the fluid. Instead, just fill the differential slowly, and stop pumping gear oil in when fluid comes out the fill hole.
Is 75W-140 gear oil good for gear?
75W-140 gear oil is a good option for a wide range of temperatures. Unlike 80W-90 or 75W-90, 75W-140 offers protection at both colder temps (75) AND fairly high temps (140). While gear oil shouldn’t spend a lot of time at very high temperatures, it’s good to have protection in those scenarios.
