Today I was going to change my differential fluids. ARB recommend changing them out after the first 1500 miles, and I am over that. I must have hit something at the B2S run because my rear drain plug is mangled beyond belief. I decided before I try to remove it, I'm going to have to grind it out to get a breaker bar in there, I need to order a new one. The metal is folded right over the hole.

WOW!

That's crazy Scott....good luck gittin her off!

wow scott, that does suck...maybe those Diff skids really are worth it after all....good luck with it:)

Been there, done that many times on the Frontier. I just keep filing away what covers the hole. Fun ain't it?

One time I had a chunk of wood jammed up there (in the diff plug silly). Had to drill it out.

*bump to an old post.. but..

what fluid did u use when u changed ur diff?

I used synthetic 75-90 gear oil. Make sure it is API-GL 5 fluid.

The rear takes 5 7/8 pints and the front takes 3 1/8 pints, so you will need 6 quarts to do both. The stuff isn't cheap. but it is fairly easy to do.

thank you i know a guy that deals royal purple.. ill get it through him
