    Started to work on the Geo disc conversion on my 58 and found things I wasn't expecting based on what I had read in advance. I started on the driver's side and it still had the left handed studs. First of all, after pulling the wheel, the brake drum wiggled and the studs did not appear to be the swedged one I had read about. In fact the drum was on the outside of the studs and just wiggled off. In fact once the hub was off, a fairly easy pop with a hammer and the stud piped out.

    Then with the dust cap removed, a PO at some point had bent up the lip of the washer to prevent the hub nut from spinning. Then there were 2 of these nuts with this bent piece between them. Is that correct?

    Eventually I got it all out along with the bearing and then the hub easily pull of off with my hands. I never had to use the 5 arm hub puller I bought in advance just for this process. Did a PO change something or were things different for a 58 then I had read? I'm confused.

    I eventually got the brakes and back plate all removed. A light tap with a rubber mallet separated the backing plate from that center cylinder piece. I'm assuming the way this thing goes back together is that center piece, then the special made Geo caliper bracket?

    I also slipped the disc over the hub and bolted it to the wheel. It's just a little short but I'm thinking add a 1/4 inch to length and the threads would pop out past the nut. I'm pretty sure I'm going to change out the lefties for standard rights while I'm at it just to avoid future issues. I know it's not 'original' but I'm afraid at some point some less experienced tire changer will mess up and create issues.

    Everything looks to be right.
    Yes the lock washer bends over to prevent the nut from loosening.
    The hub puller is for the rear tapered axle not the front.
    You really should buy a Factory service manual as from your comments you might need a little bit of help making sure you get it all back together correctly.

    Thanks for the response. I do have one but forgot it up at the mountain cabin last week. I was reading up on something else and realized I left it next to the bed. The wife thinks I'm strange reading tractor manuals in bed. I tell her it's a jeep not really a tractor. But I did find an online PDF manual tonight that I now have on my iPad. I see where there are 2 nuts and it mentions bending the washer over. I've just never seen that sort of arrangement and it looked strange.

    When I updated to front disc brakes, I had the same problem with short lug bolts. I went the Dorman website and found longer lug bolts to correct the problem. In my case, I used Dorman P/N 610-219.1. I noted this in the "Front Disc Brake Tutorial" thread that Forker created.

    Used to be absolutely standard on many vehicles. I didn't know it wasn't now.

    The last time I recall messing with front wheel bearings and pulling it all apart was on late 60's pontiacs and they just had the single nut, washer and a cotter pin. And of course on newer stuff like my Avalanche, you just unbolt and replace the whole hub. No messing with bearings as its all sealed.

    Oh hell. Now I'll have to avoid tire places if I see a jeep parked anywhere near. It getting too complex. :(

    If it's a Jeep guy doing it then he should know to look for left hand lugs. :D

    My FSM from '69 says to bend the washer over the nut. If you look at Walck's it shows the new style washers. I prefer the new style which relies on the outer locking nut being tightened properly versus the tab being bent over.

    Glenn can you show the link to the washer? All I see on Walck's website is the crimp style washer and the first washer that goes between the bearing and first (inner) nut.

    That is the "bend over" lock washer we are talking about. There is an art to getting it right. I always tighten the first nut tight, then back it off. Then use the socket alone to "hand tight" Then place the lock washer on and tighten the outer nut, check rolling resistance and finally bend a tab.

    I'm familiar with the ones with the tab on the outside that bends over the flat section of the hex nut. I only see the washer that goes against the wheel bearing, then the nut, then the "lock" washer, then the outer nut. Are you saying to bend an outside section of the sandwiched washer? I'm not seeing any tab on it.

    Of course after looking at Mickey Kelley's picture I do understand what you mean. My bad.

    But if I put rights on and he assumes it's original......just saying you can't win no matter which way you go.

    Any pro is going to look for the L on the stud or the detent cut in the lug. No worries.

    Today I spent trying to get a broken bolt at some time in the past out of the hub and chasing conversion bolts. Finally too hub to machine shop and they ended up have to do a heli-coil. As for bolts, I've given up on them. Just too many times they either don't have or only in bags of 50. Finally found place in SA where I can pick them up in morning. So I'll post more pics as I move forward.

    You're going to love those brakes. Make sure you're properly proportioned for Disk/Drum now.
