I would pull the covers on the initial OC if for nothing else but to inspect everything. I do it to also clean out any "goo" which collects at the bottom of the housing. Both of my axles had rubber coated metal gaskets which were reusable.
Yeah I ended up buying the Amsoil Slip-lock, obviously it was developed with there own products in mind and should work good.
Just a follow up on this. I've been using the above setup without issue. I used 2oz (1/2 the bottle) of the Mopar FM in the rear to supplement the unknown amount of FM in the Valvoline. I've put 5k miles on it, including a 2,700 4th of July cross country trip and all is well.
I just finished up breaking in my gears that I had installed but will be swapping the fluid out hopefully tomorrow. I saw what you’re running and was going to go with it since I have the 30 front/44 rear with anti slip(similar to LSD). Is there only certain brands that are available for the recommendations from the owners manual? I was planning on getting the royal purple brand from my local Napa store. Also, what do y’all do with the used fluids? Is there normally a turn in spot for old fluids? Trying to do everything on my own after the initial free services from the dealership to avoid the service costs that I almost got pushed once($320 per axle on my JK).
I think it would be good, but there are excellent choices for much less money, like Valvoline, Supertech, and Mobil 1.
Thats exactly what I bought several weeks ago for my wife's Recon. Although it only has 5,000 miles on it, lots of people suggest changing the rear diff fluid early so that's what I did.
Based upon the metal that I had in mine, I would change it. The vast majority of axle wear occurs at 15K or less miles.
Awesome yeah my old jeep had a Dana 30 up front so I wanted a good recommendation I appreciate it!
