rear end gear
I think when the previous owner of my truck put the 35in tires on he also put different gearing on the rear end housing. The only problem is he must not have replaced the front. So how would I find out what gearing I have in the front and how to match it?

Did he never use 4WD? If he didn't change the front then that's easy, as it's on the VC label. Figuring our the rear may require popping the cover off and reading the ring gear stamping.

No offence, but if you have to ask that question, then you should bring it t a shop or have a buddy who has done a few show you how. Installing a ring and pinion is not hard, but VERY time consuming and frustrating for a first timer. That, and it will require a few special tools that most of us don't have.
But if you want to d o a little reading on gear installs

What is it that makes you think the po did not regear one axle?

The front and rear wheels turn different speeds and cause it to hop. Also the shop on the army post has all the tools I'd need. I just need to know how to do it. I am a helicopter engine mechanic.

Yeah, that's a pretty good sign they have different gear ratios. The rear is much easier to change than the front, but the front is the one you would want to change. If the rear was regeared to lower gears for the bigger tires, you want to change the front to match. It wouldn't make much sense to put the rear back to stock gearing.

I wouldn't engage 4WD on dry pavement then, you'll break something quick. I had to use 4WD for a few yards in deep mud when I was swapping gearing in mine. Crazy! It was like riding in a "bumper car" wanting to swap ends. Are you still running the 35's ?

I consider myself a pretty experienced mechanic and ring gears are something I still won't do, especially because I don't have the right tools. The important one to have is the feeler gauge on a stand that checks back-lash. I also never bought contact paint. But I think the guy that has these, a full shop, and the right set of instructions could handle it. Apparently Twinmill can make helicopter engines work, i bet he can align a couple gears.
If i was you Twinmill, I'd just search for how-to pages on it, theres gotta be thousands of them for gears. I bet you can make it happen.
And again, for the love of drivetrain, don't engage your 4x4.

You use a Dial Indicator, not a feeler gauge ...
I have all the correct tools, As a racer I have done many many of them ... However I pay someone that does them all day long everyday for my OTR vehicles. Why, Because reading the contact area is more of an art then a science!
If they are not done correctly they will eat themselves up.
All it really takes is a good Torque wrench, A Dial Indicator and Marking Grease/Paint ... And the experience to read the contact area!
-Enjoy

I have done several ring and pinion installations over the years. Both in a shop and in my home garage (with no air tools). As noted by others it does take time, patience, some research and an eye for reading the contact pattern. There is some great info @ Ring & Pinion.
The toughest items to overcome when I do installs in my garage is running back and forth to a shop with a press, and getting the crush collar to start collapsing to set the pinion preload. Without a biga** air wrench it takes quite a bit of pull with a LONG breaker bar to get it headed in the right direction.
My buddy Sackman has a great writeup of a rebuild on a 8.8" on another forum: First time I'm exploring the depths of a COMPLETE 8.8 build (56k unfriendly) - FSB Forums. Several of us walked him through the process. He ended up with a REALLY nice pattern.
