Gear oil

Hey guys, I’m due to replace my diffs and transfer case, what is the best oil to use?I’m having trouble getting Mobil 1 in Canada .

 

Keep in mind, 14+ Tcase uses a 75w fluid not the same fluid spec as diffs.

 

I used Redline gear oil in my 2017 front and rear differential. You can get it now in either 75/85 or 75/90. I didn't do my transfer case at the same time (~50,000 miles) but have 3 bottles of Ravenol 75W sitting in the garage for when I do do the transfer case.

 

I've got some Red Line on order. It's one of the few fluids I found that meets the 75W-85 requirement. I'm assuming your truck is the same. Obviously haven't tried it yet, but seems to have a few users here on the forum that like it. Got it off Amazon

 

Thanks for the info

 

Redline or Mobil 1
