I'll be needing to change the rear diff fluid on my '86 3/4 ton 14bolt FF.

what is the recommended rear diff lube weight?

75W-90?

What does your manual say?

Some 3/4 and 1 ton trucks call for 140W.

Either way, go synthetic!

  I hadn’t seen this one posted here but may have missed it. https://www.mdpi.com/2075-4442/9/8/74 Just so I’m not burying the lede… 0w16 yes, but 0w20 wouldn’t fair much better. Still can’t figure out why everything is an oil burner?!? 🤣

  I'll have to ask Jason. I don't have a borescope. That's a really good result sir.
