Hello, I'm Chris. Thanks for seeking us for help.
There is not a torque spec per say its a rotational spec. Open the file below.
If replacing the pinion seal
If your building the axle see step 14 under installation
Below are the specs
These are for the 8.8, the 9.75 and 10.25 axle options are just about identical.
This is the kind of tool needed
If your replacing the seal which I assume you are, and if you do not have the correct tools. The best method is to install the nut with an air impact. Tighten down the nut about 3 seconds when the gun tone changes to a dull thud stop immediately so to not effect the pinion preload, the last thing you want to do is get the preload to loose nor to tight. I build a lot of axles so I can do it by feel and ear, this is a hard job to get right even for a tech and if its wrong it will ruin the pinion bearings and possibly the gears. I am heading out the door for dinner but will be back in a couple hours.
You want a excellent 5 star answer & I would like to be rated the same for providing it. Consider I don't know your skill level & I can't see, smell, hear, or touch the vehicle. It may take a few back and forth replies. Try your best to respond with good detail so I can do the same. I normally log in at 3pm and work late. A rating is required. Your rating me, what I type. I am not an employee of this website, nor have control over the fees or the time it took to get a response. If you rate negative or not at all you still paid, but I get nothing. I want you pleased with me and my efforts, so let me know if your experience here has come up short.
Thanks Chris
