Stuck Piñon nut

05Ram1500_5.7hemi · Feb 13, 2015

I'm in the process of rebuilding my rear and upgrade to an 4:10;1 rear but I've encountered an road block. The piñon nut woulnt brake free with the impact I have. From what I can see is that it's right hand thread. Any ideas of how to get the nut off?

Rent or buy a stronger impact wrench... What is the current torque rating of your impact? Is it pneumatic? If so, do you have the pressure regulated high enough? Do you oil the wrench?

If electric, that would be your problem.

500 foot pounds, it's puematic and it's at max operating pressure

Block the wheels and a long breaker bar maybe. If you have already taken everything else apart, you need a bigger gun. That is likely the only thing that will get it off. Make sure you are not using an adapter or extension or anything like they. They reduce torque.

500 isn't even enough to break an axle nut. You need 750+ to get that off (still could not be enough). You can do breaker bar with the parking brake on, and wheels blocked.

I had to get a 750+ in order to break my hub nut on my Jeep axle when I broke a u-joint. 500 wouldn't do anything but sit there and laugh at me.

You are going to need a tool bolted to the companion flange to crush the new sleeve when putting it back together. Sounds like you need to have it install to break loose the nut. Putting mine back together I needed a long bar and a strong back to get mine crushed.
I made my tool out of a piece of 3" angle iron cut out and drilled so it bolts to the flange. It is about 8 inches long with a 3/4" rod welded to it, the rod sticks out about 4 inches. I slide a 3 foot pipe over the rod and lock it up in the spring.

This my friend is exactly why I'm going to go with a crush sleeve eliminator when I do mine.
