    I need to put in new bearings, but am not sure how my hubs come apart. The plastic selector insert says spicer. Axle is standard 1/2 ton 19 spline. Not similar to stock applications in my books. Truck is 86 Jimmy. Will get some pics up in a bit.

    Here's pics. There's a clip buried in the grease on end of axle. The selector depresses and turns the two prongs on the inside. Thanks.

    If I remember correctly you will need to take that c-clip off of there. I just used a screwdriver and some needlenose pliers. Some of the parts of the hub will come out and then you have to remove the spindle nut which requires a special tool that will fit on your socket wrench. After you remove that the whole hub should come right off without too much problem.

    Thanks. I've had the clip off and nothing else came right off but I probably wasn't being aggressive enough with it. Know about the hub nut and from there on in it should be by the book.

    After the circlip on the axle I think you also need to take out the round clip that fits in a groove in the bearing hub. It is a bit of a pain. You have to get a small screwdriver or something under it and work it out. Then the locking mechanism should just pull out.

    If it is the piece that the cover screws to you can remove the clips and use two of the screws to pull out the locking part.

    if you can afford it replace those spicer hubs with warn, they are alot easier to install and they are also more reliable

    Thanks all. Job done. I had a wobble in a wheel and it was pulling when braking. Bearings were good. Lock nut was just loose. Tightened that up to specs and inspected everything and works great now. I'll go back in later and replace with Warn locks. Nice to know how to tear down. Wasn't hard but didn't take the races out, hardest part.

    Definitely wrong. The Spicer hubs are MUCH stronger, and much more desireable. I wish they were still in production, they'd sell like hot cakes.
