Differential Fluid Maintenance
How often should I be replace the differential fluid on my truck? The dealership said that I should change it every 15,000 miles. I have 17,000 on my truck right now. The cost of doing this is almost $300!
I consulted the manual and Schedule B doesn't even mention replacing the differential fluid (front and rear axle fluid, is what I assume this is). Schedule A lists a replacement every 15,000 miles. $300 every 15,000 miles is going to add up.
I've only towed my 6000 lbs travel trailer maybe 2,000 miles out of my 17,000. Other than that, the truck is a commuter vehicle during the winter.
