PolarYJ: NextGen
 

it's finally here!!! the moment i get to stop setting up the house/shop and get back to wrenching for the fun of it!!!

So the YJ is going under the knife again, but this time not just a restoration, i'm making changes. i built this configuration with the d44/12bolt back in about 2005. i put these specific IROK tires on it in Jan 2007. things have gone well! but 13yo tires are like driving on grease in the rocks, the 12b is machining it's own ring gear away, and the d44 is cracked and bent and bandaid'd in multiple places. no more spares or hold-overs, it's time for new.

Enter ... the 40s. i got a pretty solid deal on 6 40s that i couldn't pass up. not sure why i need/want 6, but that's what there was. no way i'm putting 40s on 1/2ton axles, so it's time for beef. rear axle is getting an exact duplicate of the full-float 9" in the TJ. same width, same components, just leaves vs links. simplify spare parts and the axle really does work well. front is just getting a GM Dana60, cuz the front is already a GM d44 and this should basically bolt-in. 5.38s, Yukon Competition Zip locker f/r (air operated normally spooled) rear is also getting another 2" of stretch via offset axle perches, and the front might get an inch somehow.

last night i got the 12b out, shockingly everything came loose easy and it fell right out. the only surprise was that the slip in my rear drive shaft was bound up SOLID. glad that didn't break my t-case.

How is the tub doing these days?

Glad you came to your senses and are bolting in a GM D60 :lol:

hey, these axles were awesome for a LONG time ... all things considered, i'd not change the past.

a few years ago i did that "frame off" resto and fixed a LOT of the rust in the tub. not saying it's perfect or super pretty, but still more solid than i need to beat off rocks :thumbsup:

No, I meant vs. building a custom 60-9 for the front. Swapping a GM D60 makes way more sense IMO. I agree that the outgoing setup treated you pretty well.

Forgot about that other work you've done on the tub :thumbsup:

Hurry up and get this done...I'll be honest, want to see that truck progress more :lol:

Excited to see another build tho, I'll live vicariously through you since I have no patience, time or space :p

I got to ride in Steve's C3, so now you need to get this ready for Moab so I can take a peel in yours, too ;)

OOOHHHH, absolutely. for this jeep i the added weight actually makes sense too. i really need it down low n fwd to help me climb better.

so the YJ has to be trail ready for a run April 17th ... after that the '55 gets pulled back out for a summer project.

got the axle flanges and spring perches all set up last night and half burned in. tonight i hope to finish welding those and bend/weld on a matching tube truss to the TJ.

still missing shock mounts and the traction bar mount, but will probably install those with the axle bolted into it's final place. need weight on it for the traction bar and to flex it for the shocks.

also, these ruffstuff 2+ perches are awesome.

I used their 1" offset mounts (really just perches with 3 holes drilled in them) for the j10.

i re-drilled an extra hole 1" offset into the 12bolt perches, so i only gained 2" from these. but should be just enough to keep the 40s off the body behind the door.

When you doing the round headline conversion :lol:

:roflmao:

Sure it is, I just Googled it and look what I found :lol:

Cutting will be required :lol:

i got the flanges and perches fully welded last night, then built and 50% welded the truss. it's the same link mount truss i put on the TJ since i had a spare plate already cut and the tube lying around. pretty sure it wasn't needed, and pretty sure it isn't adding a whole lot of extra structure, but the plate actually ended up basically dead level with the spring perches!

i don't know, B ... that might be worse than the angry eyes!

Yeah, I'd go w/ it's actually worse than an angry grill myself :yuk:

Honestly, had to rib a bit...I had a YJ, loved it!!! While the square lights veered from the original look of the SWB, I still wholeheartedly believe that the grille should simply not be messed with...factory all the way. Be it any model out there, it stays ;)

what ya think B, 40s on the 55?

it happened, i got em on there this weekend. the stupid Chineseium wheel bearings didn't fit, and no one local had any better, so i ended up scavenging the Timken's from the front 60 :lol:

love the new departure angle, not super excited to go to a mini-comp-cut to make them fit. but i'll make ti look good i hope. with the tire and slightly taller spring perches, the frame gained 4 full inches of clearance. now i have 13.5" under the diff, 24.5" at the skid, and 28" at the frame. i kind of wish it was a little shorter maybe.

left it all stripped n ready for the front 60, just need to sort a few things out first. drill n re-tap the spring plate stud holes, new center pins in the springs, and both fixed spring hangers have rips in them. so getting new HD hangers, mounting them 1" fwd, and re-drilling the center pin holes on the axle 1" off. the shackles were quite vertical, so they shouldn't even notice extra inch.

:lol:

I'd be as good w/ the 40s as I would w/ the low rider...but those really belong on the Jeep ;)

That departure is pimp as hell!

Ok, when ya gonna hit the trail w/ some of us :dunno:

ASAP!!

seriously though, this summer will probably be local shake-downs and re-learning, along with rebuilding the savings. but i REALLY want to get out and do some new stuff bad. i REALLY want to get out west. moab would be like $1500 in fuel, maybe i can find a passenger who would like to split some of that.

:chug:
