    I greased my u joints using Mobil 1 but noticed it leaks out of my grease gun in the hot garage. I noticed some splatter under the truck which may have been what I didn't wipe off. Do you think the grease leaks out on its own? Which grease should I switch to if anything to prevent leakage? Thanks.

    When the joints are greased it pushes out old grease the rotating drive shaft throws it out some lands on the truck look at it as rust proofing.

    Your grease gun leaking is quite different that a U Joint leaking. I use Mobil 1 grease in my gun and there's a little leakage here & there on the gun. Doesn't bother me enough to worry about it.

    As maineah (fellow Maineah here too) stated....any splatter is a result of the old grease being squeezed out of the fitting. Highly unlikely your U Joints are leaking grease.

    There's always some amount of splatter if the u-joins are greased properly. It's when you don't see any grease that it's a problem. I use Valvoline Crimson grease and it oozes out of the grease gun a little bit because it's under pressure.

    Mobil 1 is perfectly fine...you're good to go! Good to grease those joints at each oil change & more often if your truck sees a lot of water.

    The Mobil 1 grease you are using, is it NGLI #2? #2 is a higher viscosity grease than #1, and better in warmer temperatures, while #1 will outperform #2 in cold temperatures. #2 is recommended for general purpose and u-joints in a wide range of temperatures that cover the vast majority of where Tacomas will be found. If you can't pump #2 out of a grease gun, and use polar bear hide of penquin skin to wipe your hands at the end of the job, then consider #1. :)

    Properly greasing is less common
    You have to push out the old till you see the new.
    The more new you see the better you greased it.

    The u joints are definitely leaking the grease. The centrifical force of the rotating drive shaft is throwing all the grease to the outside of the spider.it will push through the bearings and out the little Rubber seal at the end of the cap.
    Unless the spider is cracked of course...

    Nothing to worry about tho. The needle bearings are always getting fresh grease.

    The zerk usually squirts a little as it's seal closes. Push on the little ball at the end of the zerk, it should pop back to close.
