Got a lot done last night.. The goal was to pull the turdy five and get the 8.8 mocked up.

I started working alone but soon a crowd began to gather..



The obligatory 'pulling the turdy' picture



Got shorter T-case bolts and got it back to stock height for the SYE.

Hold it right there, I know what you're thinking. "Why didn't you do a tummy tuck?"

Well before you ask I'll explain my reasoning..

1. It really isn't necessary for the wheeling I do right now, even though I want to do it.
2. Since I'm eventually doing the 5.3 Vortec swap, I'm trying to put as little money as I can into this engine and trans.
3. I'm getting sick of spending money...



Something seems to be missing here..



Got the springs and everything mounted up to the 8.8

If you look closely, you can see the turdy five sulking in the background..



Just the U-bolts holding everything on, the perches aren't welded.

The plan was to get the 8.8 under and still be able to rotate the pinion, didnt work out quite as planned though.



Put on another buddies' 31's so we could just roll the 8.8 under the jeep



Trying to set the pinion angle here..





I say trying because all we ended up doing was getting a pretty good estimate of the angle I wanted it at.

Which was 18 degrees..



Then we pulled the axle back out, set the pinion level..



And then put the angle finder on the perches..

17-18 degrees was about right since I wanted the pinion pointed at the output of the T-case (SYE)



Then I tacked in the perches and shock mounts



I positioned the shock mounts so they'll be flush with the bottom of the axle



Got the turdy back in to the jeep so I can drive and stopped here for the night

Just a suggestion.... You might want to wait until you get that SYE installed before you go and burn those perches on permanately. The reason I say that is your t-case output is going to be different. I just went through this myself. A lot of guys will tell you to point the 8.8 pinion straight at the t-case and some will say 2* degrees down ( to account for axle wrap during acceleration). I went the 2* degrees down route and I dont get any vibes. Im not saying you have to listen to my advice, just reconsider. I know this is your dd and you want it done right cause those perches are awfully hard to move once you burn it all together. As always keep up the good work

I agree with skyj, dont burn them on permanently yet until the SYE is on there. With a CV DS, pointing straight at the TC is fine, with a non CV DS, 2* down is about right.

I really would have loved to been able to do this but it just wasn't going to be practical in my situation.
If I waited until the SYE was installed to set the pinion angle that would mean I would have to set it, pull it back out, weld it, paint it, etc. then put it back in later.
You're correct this is my DD and going that route would mean at least three days or so of down time.
That's just too long and I know i'd feel rushed to get everything done, so the way I'm doing it will have to do.
Also I'm pretty sure that the angle will do alright, I called up TW's and got a measurement of how far the SYE will stick out. Then I set the pinion going by that measurement.
And I did final weld everything anyways Thanks for the tip though, I'm always open to suggestions

Good question, lets see here:

-300 for the axle
-45 for perches, shock mounts, spring plates
-40 for U-bolts
-570 for SYE/DS
-45 for new bearings and seals
-130 for diff cover
-35 chassis saver (but I actually got this for free)

That would bring the total to 1165 + 260 more expected

I think that's about it so far..

I'm expecting about another $200 or so for brakes and $60 for gear oil.

It's really the little things that add up quick though, like cut off wheels, welding rods, etc.

Thanks!


In case you didnt read all that above, everything is now final welded.

CDW_327 was kind enough to bring over his arc welder and generator (no 220 at my place) so I could weld everything up.

Considering it was my first time arc welding, I think it went pretty well..



The welds aren't cleaned up or made pretty or anything yet. I'll get to that in a couple of days..

For any of you doing this too, these are the measurements I used..

Don't grind down those welds too much you will weaken them. From the pic it looks good I haven't arc welded for a long time. You should have bought a can of anti spatter less cleanup. Are you going to weld up the tubes, to the diff?

I wasn't planning on grinding much. Mainly just to get rid of the spatter and what not.

And yes, I welded the tubes at the same time as all the mounts. I think it came out pretty well.

I'll post up some better pics soon.

thanks! just was looking into doing this soon and was seeing how much you spent on getting the axle done. Great job btw hope to be doin this soon once i can get my hand on an axle

Don't want to hijack, but I didn't want to create a whole new thread. Just completed mine, and it works quite well, only had to re-flare brake lines once. Only about $750 in to this build. Still need to extend my upper shock mounts as you can see.

Lutzke21 that axle came out pretty nice! Seeing your shocks makes me worry how much room I'll end up with though...

Received a nice care package from TW tonight

That picture of Lutzke21 reminds me of my shocks when i first installed my 8.8 I did a little write-up on my fix for it. Granted Im running Wagoneer springs with a 2" stretch so it will be a little different than you but since you guys know how to weld. here is the link to my shock extensions.http://www.jeepforum.com/forum/f12/s...sions-1345960/ I gained two more inches of shock length. I also had to cut and make new shock mounts on the axle,cause I welded them on up too high (the first time). At full droop my old mounts were contacting my shock. Now I got all the bugs worked out and they work great.
