    In putting my hubs together the factory manual is a little vague. There are 2 nuts and 2 washers. It looks like the small lock ring (washer) goes in first, then a nut that sets the tension, then a larger thinner lock washer and finally the other nut. The second nut is locked against the center washer and then the center washer is bent in to prevent the inside nut from losening.
    HAVE I GOT IT RIGHT??

    The outer washer should be bent out toward the hub not in toward the spindle. It should be bent out on 1 or 2 sides to lock the outer nut from turning. If you bend it in toward the spindle your not gonna get it back off later.

    I don't understand. First of all if we are talking about the same thing, the washer on mine is fairly thick and it won't bend outward. Mine bent onto the inside nut but it took a hammer and punch to do it. It will still slide off the inside nut if I take the outside nut off but it will not keep the outside nut from backing off. that doesn't sound right. Seems to me it should bend outward locking the outside nut.
    I am not at all sure the ones I have are the correct lock washers since everything was mickey mouse on the hubs and front brakes. I have new one on their way from 4 wheel hardware. Christmas mail held them up. I'm planning on getting the new hub all pressed together; studs and races so as soon as the new locking washers arrive it can all go back together.

    that washer needs to be bent out to lock the outer nut.

    Bending it inward does not lock the outer nut, that's the one you want to lock. It takes a large flat tip screwdriver and some force to bend them outward. Sometimes a second screwdriver to keep the washer from moving helps.

    Oh yeah It helps to have a cold bev close when performing this or any other wrench turning on your jeep. See doesn't that help!!!

    Well blow me down...I've been bending the wrong way all these years...:rofl: :rofl: But I'll point the finger at PO's, as I've only ever seen this washer bent in.

    However, my washers have always come off easily even though they were bent in.

    FWIW the repair manual isn't *real* clear here - the exploded parts diagram shows and labels both the inner and outer nuts as just that - #1 Nuts, while the text refers to them as the adjustment nut and locknut, and doesn't specify a direction to bend. You really have to read it closely....

    keeping that outer nut from moving is key to having the front wheels stay on .

    I'm with Mike on this... Been bending them in for more years than I can count, and Dad did it that way as well. Mine always had a key that locked in the axle and the washer was bent over the nut.

    If you guys are bending the tabs in, its no wonder you have such a hard time getting them off. That would also explain a couple of the posts a year or so ago about a few people that busted the outer edge of the spindle hub when trying to remove them. I can take my outer spindle nut off in about 2 minutes flat once the hub is off.
    The washer is still supposed to be bent over the outer nut, not the inner nut. I'm not trying to be obnoxious or upset anyone about this but this is how its suppose to be regardless of how anyone learned it. What Patrick does is perfectly acceptable cause he's covering both bases but locking down the inner nut only is the wrong way.

    I'll throw this into the mix. The manual is a little fuzzy on the description of what to do, but the picture does actually show the tab bent over the outer nut. However, I basically disagree with this and also bend mine over the inner nut, and use the right socket and crank down on the outer nut. I don't know about others, but my F250 internal spline hubs use the inner nut with a pin sticking out, the middle washer has holes all around, one of which has to line up with the pin. This locks the inner nut in place, then you crank down on the outer nut. Both nuts have the 4 grooves in them for the weird socket. My M37 is like this also but uses hex nuts. To me securing the inner nut, since it's the wheel bearing adjustment is the logical way to go, then locking it down with the outer nut.

    Thats because you're not locking anything!!!!
    The outer nut is still what keeps the wheel from falling off.

    How are you getting to the washer to bend it back straight. I just tap mine with a screwdriver about twice and pull the nut off. If you undo the outer nut how are you bending the tabs back straight from being bent over the inner nut. ther simply isn't enough room in the hub to bend the washer over the inner nut and do it right.
    I still stand, if you are bending it over the inner nut only, you are doing it wrong and the outer nut can come loose and the wheel come off, simple as that.

    Glenn by locking the pin to the inner washer you are still locking the outer nut sincethe inner is keyed to the spindle.
    Bearing preload has nothing to do with the outer nut locking or not, if the outer nut fails and you can pull yours inner washer off easily to rebuild imagine how easily it will fall off if the outer nut comes loose while driving.

    With the pin type inner nuts and the holes in the washers the only thing locking the outer nut is friction from cranking down on the nut with the socket. The pin and washer combination clearly locks the inner nut and has nothing to do with the outer nut. I understand what you're saying about the outer nut coming off, but the tightness is what holds them on in these examples.

    Really, go loosen your outer spindle nut about 1 turn and lock the washer the way its suppose to be, I guarantee that you can't get it off.;) Friction has nothing to do with this design. Its simple and effective, the groove on the spindle holds the key on the washer and keeps it from turning, the folded edges over the nut keep it from turning, with that said the inner nut can only unwind enough to hit the outer nut(wheel stays on). With doing it the other way if the outer nut falls off, the washer flops out and the inner nut can unwind and the wheel falls off.
    And as far as the pin type, the iner washer is still keyed I would imagine and if it is the pin still locks the outer by keying it to the groove on the spindle thru the inner keyed washer.

    The "bent tab" washer was designed to lock the jam nut into place. The bearing pre-load is set by the inner nut. Bending the tabs inward "sorta" holds the preload, but does nothing to hold the jam nut into place.

    In addition to maintaining the "lock" on the bearing preload, having the outer nut back off is a sure way to trash the innards of your locking hubs. Learned that one the hard way in a past life... :rofl:
