All done!!
Well I'm finally all done with everything, just gotta grease up the front driveshaft and get it in there. Everything works great and it crawls like a Turtle!! I'll post a video of it crawlin later. Oh, and forget buyin a shifter boot from Marlin for 55+ bucks, got this boot and trim from Kragen for $10!! I think it looks real good.
Oh and one more thing, big thanks to Driveline Service of West Sacramento, I'm very impressed with their service, and did a great job with the rear shaft! I'd recommend them highly to people in the area.
Just for the heck of it... doors back on and ready to drive back down to Vegas!!!!

Thanks guys, I'll get the video up tomorrow!
Yup, I made it myself, $30 as opposed to $200 to get the stock one lengthened. It doesn't matter if it's balanced cause it's only used in 4WD and I have manual locking hubs so it doesn't move in 2WD

Nice work. I'll be curious to see how you like the xmember you got. I hated mine. Hung down as low as my gas tank and hit on everything. So, I got rid of it and moved stuff up:

You have a body lift for a drivetrain lift?

So I ran into a problem puttin my front driveshaft in, the stock CV joint I used for the front hits the crawl box I think I'll have to get triple drilled flanges for the t case and the front diff and flip the shaft.
What have people with this setup done? Did you have the joint chaned, or did you flip it? I don't wanna have to make a new shaft so I think I'll just flip it with the triple drilled flanges cause cause the ends are two different size bolt patters which is weird.

Be careful here.
The way a CV joint works is that it does not change angular velocity through the joint, no matter what angle you are at. The U-joint on the other end of the shaft, however, does change angular velocity.
If you flip the shaft, you must make sure that your u-joint has zero angle to it. I doubt that will be possible with your set up, but we'll see.
If your angular velocity is not conserved throughout the driveshaft, you'll get pretty bad driveline vibrations. Granted, you are only using this shaft offroad, but its still not good on the bearings.
Mine was close to the adapter, not the crawl box. I just used a grinder to trim about 1/16" to 1/8" off the side, and it was perfect.

Thanks to your advice Ike, I ground down the adapter and now I have a front driveshaft!! Thanks for the help!

Drivetrain vibration sounds like noise coming from the transfercases themselves. Bad vibrations will sound like your tcase is about to blow up, and a very mild vibration will sound like a very soft gear chatter.
I've never seen anyone who hasn't had chatter with a one piece rear shaft and dual cases, but I've only seen a few. If you don't have any vibes, that is awesome, and count your self lucky.
Cheers!

How would people with a 4 inch lift and no drivshaft modifications get away with it then? Sorry for all these questions, this driveshaft thing is new to me Thanks for the help!

Sounds like you don't have anything then. The sounds usually are there all the time, but sound worse when coasting.
People with a 4 inch lift don't always get away with it, but do some of the time because with a u-joint shaft, when they lift the drivetrain away from the axle, they often change both the upper and lower angles the same amount, which means that both U-joints are at the same angle, and hence, no change in angular velocity through the shaft. Angles cancel.
With the duals, you're changing your upper angle more than the lower in most cases, and vibrations ensue. Sounds like you got lucky with your set up and things worked out nicely so that you changed both by the same amount.
That is awesome!

Thanks for all the help! I remember you answered some questions a while ago for me when I was curious about puttin two stock cases together as well.
