    I recently tore apart a 14 bolt FF from a '79. I pulled the axle, the outer locknut, the ring with tangs locking the inner nut from spinning, the inner nut, a washer, and then I got to the bearings. That's all that was in there. The thing I have a question about is that ring with tangs which locks the inner nut. Both of them (right and left hub) are kind of mangled. When I pulled it out, only one of the tangs was engaged in one of the 6 indents on the inner nut. It looks like that tang was pushed in a bit to accomplish this. Should they all be pushed in so as to lock the inner nut better? I'll probably buy new ones because these ones are pretty dinged up. Also, one of my manuals (forgot which one) shows a keyway that goes on that groove in the spindle. Mine didn't have that...should it? I can't even think how that would do anything because there is no keyway relief ground into the nuts. /forums/images/graemlins/crazy.gif

    Any help/advice is appreciated. /forums/images/graemlins/thumb.gif

    both washers that come out should have keyways in them...i have the GM part numbers for those washers... the one with the tangs locks the outer nut, and the other goes between the inner nut and bearing..
    inner washer:3663658
    outer washer with tangs:3663659

    Ok, sorry - I didn't make that clear I guess. The two washers (flat one, and the one with tangs) have a "key" formed on their inside diameter - so, looks like I'm ok with that. My question was, the manual I was looking at (must be Haynes because it was a photograph) showed someone actually pulling out a 1/4" x 1" long key out of the end of the spindle /forums/images/graemlins/crazy.gif Must be a different design.

    How does the washer with tangs lock the outer nut? When I took the hub apart, that washer was in between the two nuts with the bent-over tangs facing the inner nut. /forums/images/graemlins/1zhelp.gif

    that key is certain setups only, its a haynes manual for sure...the 79 14 bolt i just had into didnt have that key...the washer with tangs should have one tang or two bent into the indentations in the outer nut..to keep it from backing out even though it gets heavily torqued..

    The washer with the tangs on both the inside and outside of it grabs onto the indents in the outer nut IIRC. I wish I had a pic due to the fact that I'm not good at explanations /forums/images/graemlins/smirk.gif

    So, sounds like the washer with tangs was put in backwards in my axle /forums/images/graemlins/thinking.gif. Probably doesn't make a whole lot of difference which one it keeps from spinning, but I'll put it in the other way when I assemble it...thanks. /forums/images/graemlins/thumb.gif

    Wait...doesn't it make more sense to have that washer with tangs lock the inner nut? I mean, think about the front axle...you're dealing with a similar setup. Sure, by having it lock the outer nut you're keeping it and the inner nut from backing out, but what about the inner nut spinning in towards the bearing? I'd rather have it lock the inner nut and rely on torque to hold the outer nut in place. /forums/images/graemlins/thinking.gif /forums/images/graemlins/1zhelp.gif /forums/images/graemlins/crazy.gif

    yes it was put in backwards...new ones cost me 4 bucks a piece wholesale..so its worth it to get at least new lockwashers so you dont have to worry about breaking the tangs

    not a problem...if you need any other 14 bolt parts, most everything is listed in the advanced preview section under post "list your part numbers here"...good luck
