    First oil change and differential oil change

    Hello everybody. My first Oil Change came up and my Ineos dealer at Rusnak said that it would be just under $1000 and that would include an oil change with the Castrol LL 17-FE+ and filter, the front and rear differential, and a cabin air filter. I usually do the oil change itself, but I...

    2025 U.S. front differential metal in fluid

    Significant metal in front diff fluid. Ineos says it's fine because function is fine. Obviously incorrect. Anyone have the same problem but ineos acknowledged and fixed? Anyone have workshop manual for the carrano diff so I can do it myself. Dealer says they can't support me because ineos said...

    Front differential, rear differential, and transfer case fluid levels

    There have been discussions about whether you fill the front and rear diff fluids up to the fill hole, or if you're supposed to fill both up to I think it was 23mm (or 31mm?) below the bottom of the fill holes -- I forget the actual values that were being bandied about. Has anyone found...

    How wet is your differential case?

    I was just doing a routine check of my Grenadier this afternoon and noticed that both the front and rear had a trail of oil and a larger pattern on the case. I know a small amount is ok, but is this too much?

    Gents, check those differential fluid levels!

    Greetings fellow IG drivers: Took new delivery IG SW June 2024, with relatively little use (<1,900 miles) ahead of May 2025 Moab Gathering.

    High pitch sound when towing

    Does anyone know what this sound could be. If you turn it up you can hear a “whine” when pressing gas. Did not do this until towing. 3800# trailer so well within the capacity. https://391dave.smugmug.com/Grenadier/i-DcSsHnm

    Changing the Differential Fluid

    I've never done changed diff fluid before so I am going to put my pride in the backseat and just ask. Are these these the drain/fill ports? From a process standpoint, my understanding is that this is pretty simple. 1) Start with a warm axle 2) Remove fill plug 3) Remove drain plug & drain 4)...
