Here is the tool which is called a Differential Bearing Preload Wrench and you can buy it for 50 bucks, or you can make your own like I did for $2.37:
From what I understand, this tool will work for the Chrysler 8.25 as well as the Chrysler 9.25. It may also work for others.
Let me know if you have any questions as I’m happy to help!

Amazon has it. I bought it for 29$ May 2022.
Doing this right now . . .
I don't have a nut that big, so I'm welding 1/8" plate all the way around the biggest bolt head in my junk can and it comes out to right at 36mm.
The bolt is going to be welded directly end to end with 1/2" rebar that's been wire wheeled down to shiny and spun around the belt sander to give those rebar curls a nice smooth feel.
On the end of that I'll weld on a 1/2" drive 1/2" socket (an extra / sacrificial socket).
It'll be one piece from end to end 32" long (so I don't have to stretch any further than necessary to reach it while rotating the ring gear for play).
And best of all, it'll be a nice solid tool to add to my collection and save me $150 too.
Cheers ๐
There's a hint in there for you dude, if you haven't already . . . stretch yours with some rebar and make it one piece. You'll be glad you did.
Nice video too sir.
Thanks
thank you. is there an adjuster on the right side only ??
A length of 3/4 black steel pipe and a standard 3/4 to 1 1/2 hex bushing (with a washer glued or tacked on behind) will also work https://www.youtube.com/watch?v=xlCamOSJEXs
Where did you bought the nut
The correct nut size is 36mm then you won't have to grind it down.
Use this same size threads with a lock nut… its the perfect size no grinding needed and then weld a socket to it
Thanks brother!
Great camera!
I used a 1inร 1/2 threaded nut and a 3ft piece of threaded gas pipe with another 1by 1/2. For about 18 bucks. Yours is way cheaper. Wish I would have seen your video first.
So what did you actually use? Is that a nut you pressed into the socket?
A 36MM CV AXLE NUT works perfectly!! and one of my spark plug sockets also was the perfect size for a press fit into the nut i had lying around in my nuts and bolts bin.
OTC 6602 Differential Bearing Preload Wrench. Advanced Auto, Walmart and Amazon can ship it. Amazon and Walmart were the cheapest. Sucks to buy the tool, but I'm glad for no shims!
Great tip! Thank you!
Does this work to remove the carrier as well?
What an awesome idea! With it you can go to a junkyard and easily grab a posi unit if need be or work on your own axle at home. Thanks for posting this.
I Like The Visual look Inside I Would Get Real deal All those Extensions Would Make me Nervous But Cool video

After you set the backlash tighten the carrier caps to 90 foot pounds then tighten the carrier preload with the tool to 75 foot pounds recheck the backlash if it changes readjust but usually it want move once you've tighten up the carrier caps hope this helps you.
What did you torque those carrier bearings to? Did you check your backlash while Tightening back and forth?
