    Plastic cone fell inside front diff

    I was almost done with my front diff fluid flush when the black plastic tip from the Mobile 1 75-90 quart fell into the front diff fluid hole. Has this happened to anybody on here before? I saw a thread about a tip in the t-case, but didn’t find one on the front diff. Will the tip get chewed up...

    What Gear Oil is everyone running in 2020

    I can not seem to find a recent thread on what gear oil and ATF fellow 80 series owners are running in the recent years. Thanks in advance for everyone's suggestions. --Chase
