    Yesterday doing my pre trip I noticed a big puddle of oil inside my right rear outer tire on my tractor. I go the a good year about 90 miles away they say that two screws were loose. So they end up doing what they do and clean everything up. $115 later I was heading back down the road.


    Throughout the remainder of my trip which was another 300 miles I'm checking the tire and see no oil leaking.

    But this morning when I wake up I see another puddle in the same spot inside the tire except this one is way smaller almost to the point of being miniscule.

    What could be going on

    If you can see oil sitting in the outside of the rim, the axle flange gasket is the likely culprit.

    They either did a poor job of cleaning up or the new seal didn’t take/was put in wrong

    Tightening up the outer hub bolts won't fix the bad seal.

    Seals usually go out because of oil contamination, mostly metal. I'd check the bearings.

    If its on the outside of the wheel, its not a wheel seal. OP said its on the inside of the OUTER rim. I interpert that to be the axle flange gasket.
     
    Dino soar, Dockbumper and 650cat425 Thank this.

    That is exactly right. Main cause of this failure? The axles are pulled on these trucks during piggyback transport. Square pieces of plywood are put on the hub to keep the oil in. When the tractor reaches its final destination, the axles are re installed, lots of times with a damaged/missing gasket, and I would assume without a torque wrench. There are lots of "wrench holders" in this industry too!o_O

    I'm not sure how they get away with doing this as the axles are designed to carry the "oil" from the diff housing to the axle/hub bearings and therefore lube the seals, and then the oil would flow back to the diff through the axle tubes.

    It may be ok for a while, but alot of trucks are getting pulled out of mexico...

    They tightened the bolts but didn’t replace the gasket.

    Had a few trucks where I worked that needed to be drilled out and helicoils put in.
