14BFF burb Install

ok, so I've been slacking off a bit. I've done what I could here and there, cleaned up this and that etc. Needless to say I've gotten some parts in, and it's that time to get moving. I miss my truck!

First off, stupid question. When I took the springs put I didn't make note of which way they came out. :o Silly me, i realized the other day each end of a single spring are two different lengths. Which end goes forward?
I installed the longer end towards the front. Made sense at the time but now I question it after looking at it. :whistle:

springs installed. ( 54" btw )

Ok, so hopefully everyone can see how the burb is situated. It's that time to actually put the axle under the truck and get the pinion angles sorted out. I was thinking basically, hooking everything up, i.e. axles spring perches,u bolts etc, but NOT welding the perches in just yet. But, rather having it all "loose" so to speak, but attached, then using a floor jack to raise the axle just until it starts to raise the rear end. Lower it just a tad the make measurements, adjust accordingly till I have it right, the as it sits, tack weld it in. Thoughts on this idea??


On that note. Pinion angles. I'm sure I read some were 3-5* is good?. I thought I also read 0* is optimal ?? That being said I asssume that the difference between the drive shaft and the pinion correct??


Since I've been awaiting parts , one night I thought I'd try my had at a little diff bling ( thanks to diy4x for the quality thinking time :D ) btw, diy4x has some beefy sh*t. :waytogo: glad i got it!

You oughta throw discs on that axle while you have it off! Its not much even if you buy the calipers and rotors new.

Silly question about the disk conversion.. If I do this. theoretically, should I be able to fit the same size wheel (15") ? ANyone know if 15" wheels are available ? GOOD LAwd that'll save me some coin!
 
COOL! So I got this Biiatch installed! little of what was done.
And Thanks to Texasrebel4x4 for the text help and pics :waytogo:

I was really stressing about all this, turns out it was really quite easy when you take your time. Measure 5 times burn once time deal.:D

SO , after 7 liters of water and a full day, here's what came of it all.



First things first , I slid the ole 14bolt under the springs ( naturally :rolleyes: ) and bolted it up snugly. Went ahead and raised the axle one end at a time till each jack stand was free. Supported the axle with additional jack stands, at each end with the full weigh of the truck resting on the axle.

first end.

That was like the hardest part to me. From there, I loosened the bolts and nudges it to get the axle centered. 4.25" each side. After that , I hooked up the drive shaft to the pinion. I made sure the truck frame was level ( not sure how necessary that was ) then took the measurements of the U joint of the slip yoke at the transfer case. I showed exactly 6*. (Drive shaft was at 18*). Moved to the pinion. It sat right at 2*.. From there I slid the ole harbor freight floor jack under the pinion and gave it a few nudges to finesse it into compliance. Checked and I got it sitting dead nuts at 5* , 1* to allow for axle twist.

Once I was here, went ahead and tacked the perches. Lifted the rear at the axle and , sat it down a few times, ricked the truck slightly etc and confirmed my angles. ( Drive shaft remains 18* )

That was pretty much all I did. :thinking: Checked, rechecked. Sat for a little bit. rechecked it all around again. Then burned in the perches both sides on all fours.:weld:

End result, What I've read was to be a good angle and sexy 1 ton under my Burb :woot:

( sorry for blurry pic )

That being said. I HOPE everything is correct, and all that's left is fluids, brakes, wheels, and tires! :saweet:
 
congrats man, i remember swapping in my 14bff (10yrs ago) like it was yesterday. i'm sure swapping in my dana 60 will be the same way. you're doing it right the first time, sure as hell wish i had done that. looking forward to seeing some pics of the suburban standing on its own.

Thanks! :bow: I certainly miss driving it



I'm looking at some HUMMER wheels. Trying to find any info I can on these, looks like I just need lug nuts for my application at this point. I'm finding them a lot on CL.
 
SO, I'm reading up a bit here. I found two older post, and read a few other places that say I can in fact fit 15" wheels. Some wheres around 4.25" backspacing.
:dunno: I would totally love to buy some $60 15" steel wheels (8 lug) and NOT have to buy new tires for now.

link 2

15" x 8 lug wheels

Without getting them re-centered they have too much backspacking and don't fit right, though you can get wheelspacers I have heard.

Thanks man, I too have read about this, I thought I read that the H1's needed the re center and had crazy backspacing, but I know I read the H2's had the 5.75 or such back spacing.

Okay, So after much research, and measuring, I found that in fact 15" wheels will in fact fit. I orderd up some 15"x10" 's with the 6.5 bolt pattern and 3.5" back spacing. A pain in the ass to find , but Summit racing listed them. They were on back order , I took the initiative and called the manufacture of said wheels, unfortunately it'll be the 1st part of July before I get my wheels :yikes:

No less, I have more time than money. No need to waste a grand worth of tires, since mine are practically new.

Good time to sew up some other pressing issues. 3/4 ton 8 lugs for the front, AC, tune up, exhaust, radiator, just to name a few things :D



On a side note.. I wonder if I should change this to a "Build" thread ??:whistle:
 
On another Note. I am still on the fence about where to mount the shocks. WOULD LOVE SOME INPUT! :1zhelp:

Looking for best " all around " option. Obviously the way it was isn't good.
