axle install questions

Hello again gents...
So, FINALLY the axles are coming in a couple weeks...unfortunately, shortly after (i think less than a week) i have a lovely "istan" tour...assholistan, fuckthisshit-istan...for a month.
anyway, gonna try to install all my goodies at once (all before winter hits...dont want to do this crap in -40)and get ready for some future install as well .
so, the current install list is: front and rear axles, all 8 control arms, new (to me) 2.5" coils, new bumpstops....and 37s

the future list is: new shocks (october) and in about 6 months 3.5" coils. i add this info for the questions to follow

moving on.
my install procedure as best i can tell is this:
1. Remove old axle
2. Remove jounce
3. Drill holes in new axle for bumpstop bolts
4. Cycle new axle up to cups for lower control arm length.
5. Install bumpstops at projected length (2 inches?)
6. Install upper control arms at recommended starting length (more for axle stability than anything)
7. cycle axle up
8. Measure for future shock compressed length.
(May need to add bumpstop puck when reviewing for rancho 9000 shock compressed length)
9. Install shocks and cycle axle up to see CURRENT compressed length/clearance etc (in case i need to add more bumpstop for what is on right now)
10. Install new (to me) coils, etc
11. Install wheels/tires
12. Measure for caster and adjust upper control arms.
13. Check for axle being square vs. the frame
14. Cycle axle up again with wheels in for rubbing issues with current bumpstops
15. Adjust as necessary

Repeat for rear

Please tell me how my "order" looks....tips, tricks, bashing me for not going FF 60 , etc
Also, will my thought process work: When ordering new shocks, i can anticipate the new coils by simply adding 1" to my compressed length

3" bumps are typical for 37" tires. What are the new axles? WMS?

#14: cycle axle again ,with wheels/tires on , looking for rubbing issues w/ current bumpstops as-well-as full steering ,lock-to-lock tests while the suspension is loaded /unloaded.

slight mod to that number

So, axles are pr44 and pr60 ...so, stock width. Have flat fenders as well, so would 3" bumps still be the norm?

Nice catch! How does everything else look? Order-wise and general process-wise?

Just the relocation brackets, but you bring up a good point. Seems a little ridiculous to limit suspension travel for that. Can get extended lines and a few hours labor... i think i remember crown being 150 bucks or so.

you should have ordered axles at 68" WMS not stock width for 37's. You might get by with 2" and flats but when you move to 3.5" coils you will want to do a drag link flip and it will require 3" of bump anyway, that or you will be doing some frame fabrication.

good points...on both the width and the 3" bumps. not going to lie...little upset i didnt think of that sooner.

so, is the shock measuring idea in the right ballpark?

Thoughts on pushing the rear axle back 1/2"?
