I need to borrow or buy a carrier bearing adjustment tool ASAP for my Chrysler 8.25. Anybody near Georgetown KY or Lexington Hollar at me please! Its the one with the axle nut welded to a pole that you stick through the axle tube.
 
I made my own, two 3' pieces of 1/2" pipe, two 1/2" drive short extensions, and two nuts that match the inside of the adjuster(can't remember the size)

Weld it all up and you have 2 adjusters for less than $25. I always torque mine to 100ftlbs but you really can't overdue carrier bearing preload.

Also keep a close look on your backlash spec as you tighten them up, it will move and move quickly!
 
The problem isn't that I don't know how to make the tool it's that I can't get the axle nuts off the axles that I have they are froze up and I'll have to have the local driveline shop pop them off but I was hoping to get it done today an not have to wait till Monday
 
Wait! Are you stripping the axle down for a gear set-up?

If so, just remove the carrier bearing caps and then pry the carrier out of the housing. You don't need the tool for teardown.
 
The carrier pin would not come out while the carrier was still in the axle housing. According the the Aussie locker instructions if you cant get the carrier pin out then you need to remove the carrier, mark and remove the ring gear, install the locker, then reinstall and torque the ring gear and then reinstall the carrier in the housing. When removing the carrier you have remove the bearing caps, when I did this the adjustors on the side that require the special tool fell out before I could mark where they were. therefor I have to reinstall them and set the backlash and stuff again. So I have to have the tool to do this. In hindsight , I could have ground down the teeth on the ring gear but I would have had to do this while the carrier was in the housing (metal pieces are not good for in the gear housing) The gears are 4.56 gears and the ring gear is much thicker than the stock 3.55 ring gear and since it wasn't the stock ring gear the instructions as far as disassembly were pretty much useless and I have never taken apart an 8.25 so I forgot about the adjusters on the side and didn't think about dealing with that before I removed the caps. So where I stand not is I have the carrier back in the housing but I have to reset the backlash and adjust the side thingies to get the pattern and torque right again. Hint the need for the tool.

Okay, understood. I do not think you could have marked where the adjusters were and then successfully repeated the setting on install. You are going to have to have the adjuster tool to set the back lash regardless.
 
I ended up cutting a piece of my old NP231 main drive shaft off that was a little bigger in diameter than what I needed then I ground it down to the right size, then I welded it to an old tie rod I had laying around and then welded a nut onto the end of it. I'll try it out tomorrow.
 
EDIT; nevermind re read it, very confusing

What part is confusing? I already pulled the carrier so I needed to mAke the tool to put it back together... That's the long and short of it anyway
