    Hello friends,

    I recently installed 5.29 gears and an Auburn LSD to my TRD supercharged Tundra (thank you @dirtydeeds for setting it all up). I've surpassed 500 miles since the install, so I believe a gear oil change is recommended. FYI, I never tow, and but I often haul. Mostly ass...

    What would be a suitable gear oil, and how much will I need to change oil for both front and rear diffs? From what I've read, some recommend a thicker oil that would add more protection, such as Nitro's 80w-140 Para-Synthetic Plus gear oil. Would I also need to add a friction additive such as Auburn's friction modifier as per the recommendation on Auburn's website? I'm not sure what would be best.

    Thanks in advance for your input!
