Good product, good shipping

This 75w-140 is what you need for your ford 10.5 sterling axel. I did not need to add the limited slip additive. Your axel may respond differently.

I only use Mobil 1 products in my vehicles. I have had zero problems when using their synthetic greases and oils for the serviceable parts of my vehicles. I especially recommend using this gear oil when replacing fluids from vehicles with unknown service records.

Great product but they shipped poorly. Ordered 3 bottles, 2 showed up with the tips broken off! Glad I have a flexible spout funnel laying around!

Got this from amazon, It came in original box and wrapped in plastic, the plastic was stretched and was a little dirty from a garage. I put some on my truck two months ago and they're without a doubt the best product I've installed. My f150 got these and I honestly wouldn't buy anything else. Please keep in mind I'm aware there's better products available at much higher prices but I'm not a race driver on a closed course, neither is half the folks who run them but that's their money, but for my money I refuse to buy cheap off name brand junk, and draw the line at really high priced stuff that earned their reputation from spending money advertising rather than research, I usually go with mid priced stuff such as these and I found a real gem with these, I'd definitely recommend this to someone!
