    If I ever buy one, I'll probably put 500k, diff lock oil, or diff lock putty in the front diff and at least 500k in the rear. I found with my Revo while crawling that if there is a locker, spool, or heavier compounds in the front diff and you try to crawl over something, both front tires grab and try to climb over things with minimal diff action and can help drag the rear end over things. Having the rear locked up seemed to hurt the steering and didn't help push it up and over things like having some sort of locker or limited slip up front.
    Aw, Biscuits!

    Right now my Revo has Ofna Diff Lock in the front and 120k in the back, been meaning to put the 500k back there, but haven't yet. I tend to do everything from crawling to racing with friends using that truck and haven't had issues. Not sure how a Telluride would respond to it though.

    I tried marine grease in the rear, didn't work very well. After that I used JB Weld, now that is awesome! I plan on taking the front down next and adding 500k to it. The difference the locked rear made was incredible, cheaper than a locker but not reversible, if that matters.

    I'm much happier with 500k. I tried 300k, but it wasn't much of an improvement over stock. I wish there was a 750k, but the next thickest oil is 1,000,000 Gravity.

    If you want to climb, I would definitely not recommend going to brushless. At those low speeds you're going to have a ridiculous amount of cogging. But, getting a low voltage enabled brushed ESC and running 2s? That is a good idea.

    I totally agree on going for the 500k on both diffs.
    I changed it a few days ago to 500k and the difference is really amazing

    Pede Is short for stampede. 500K diff fluid is much thicker than stock. The benefit is it makes the diffs act much more like they are locked than being an open diff. It makes it act like a limited slip or positraction in a full sized vehicle. You will have 4 wheels turning more often instead of the diff slipping and only turning two tires.

    This translates into much better traction in a straight line, especially off road.
