Dana 44 pinion seal torque specs and instructions??

like the title says I need the torque specs for my rear D 44 pinion seal and the pinion nut. I did a few searches but everything I find is for a D 35. Anyone have a walk through of the replacement or any links, it would very helpful.
thanx.

Here are some torque values that you will need.
Assembly Specifications:
* Cover Bolt Ft. Lbs. 30-40
* Pinion Brg. Preload In. Lbs 20-40
* Pinion Nut Ft. Lbs. 200-220
* Ring Gear Backlash .005-.008
* Ring Gear Bolt to case Ft. Lbs. 45-60
* Side Brg. Caps Ft. Lbs. 70-90
Start tightening the pinion nut towards 200 Ft. Lbs. and check the rotation torque, If the preload starts tightening up too early or too late, compared to the nut torque, adjust the shims. Use an old pinion nut that's still in good shape to check the preload!Once that is set install a new nut and loctite it! Always a good idea to check gear/vendor manufacturers settings,they will vary, just to make sure there's no discrepancies.

Yes I've searched. If you read the first post I mention that I have searched. The problem is every search I run it pops up D 35 instructions and NOT D 44.
I need to find information (as in what to expect/maybe a step-by-step) for a Dana 44 non-Rubicon.

Pretty much the same deal.

Just torque the nut to 180 ft/lbs and you will be fine.

That's what I did when I did my 44.

Other option is to mark the nut and shaft with a chisel and put it back where it was.

Be sure to use red loctite on the nut.

If all you need to do is replace the pinion seal I'll give you a quick write up:

1. remove pinion nut.

2. remove yoke

3. remove pinion seal

4. replace pinion seal with a new one

5. replace yoke

6. replace pinion nut and torque to 200-220 ft/lbs

There you go its really easy to do.

Someone was nice enough to send me the manual for my 03 with the instructions and torque numbers. It says 160-200 ft/lbs.
Thanks guys for the help. Now all I have to do is get the fluids and seal and go to work.

lol, did yo miss the #2 post?

or just think eveyones full of crap, but decided to ask anyhow?

marking the nut is bs on a 44, which has shims, not a crush sleave.. and a d35 for that matter it could start in a different position and make the "mark" invalid for the proper preload....

No I didn't miss post number 2! I acknowledge GOLENJEEPTJ's post as informative and useful, but I wanted to get as much information as possible before I started any work. Thank you GOLENJEEPTJ for your help. No disrespect was intended.
