Thread: Rear 3rd Member Studs Replaced with Button Head Bolts?

  1. #1

    Rear 3rd Member Studs Replaced with Button Head Bolts?

    My rear 3rd member has been leaking for years, it is leaking through the threads on the studs. I plan on pulling the axle to fix the leak soon and actually bought new studs a few years ago. I am actually thinking that using a button head screw installed from the inside to use as a more robust stud.

    Has anyone done this and has a McMaster PN or specs on the screw? I can figure it out but don't have much free time to go digging before the weekend.

    Thanks!

    I'll be watching this, I have had the same issure as well.
    I believe it is something like this you are looking to do correct?

    Couldn't find my list so I pulled it from Pirate 4x4 where I got my list. I think all of the serial numbers were correct if memory serves. Check them though lol. A fair warning that this modification takes a long while. Screwing the buttonheads in from the backside takes a while. I think it took me an hour to do all of the holes. I also tried to use the same system for the longer bolts but there's no way to get them to thread from the backside sadly.

    Thanks! I have nuts and washers, so I just need the bolts. I will buy the zinc played ones to avoid the rust on black oxide.

    I ordered these: https://www.mcmaster.com/#91352a158/=16vwyvy

    I also have new long studs for the elocker, though I might end up welding up the holes and redrilling, trying to get those straighter than I did when I did it the first time.

    I just received a '98 pearl dark blue 5sp runner, haven't done allot of off roading;

    So, do the stock "wheel studs" become ripped out if the hub's when you threaten to pull the wheels off by wheeling, this is the fix that y'all are talking about?

    Thanks
