Some of you might know me, Collin, I've been to a handful of events in the last year or so riding along with @Ryanw10 or @BLZR. Well I decided to finally bring a build thread over here...I don't feel like posting all of my rebuild progress from when I totaled it until now but if you have any questions just ask...

It was stock when I totaled it and this is what it looks like now





I'm currently 8 lug rear 5 lug front. I should be 8 lug front and rear by the time I head up to Drummond on Oct 22nd. Last night I just picked up some Corbeau Baja JP Wide seats and threw them in, just gotta make a harness bar and get the 4pt's installed.





I've done all the work myself or with the help of friends so I can answer any questions you might have...for some reason there aren't a lot of JK build threads on GL4x4 :sonicjay:

Had a good time this past weekend at Rouch. Place is tiny but I got to wheel with a buddy I have wheeled with in 5-6 years so that was a plus.

This Saturday the wife and I are headed to bundy if anyone wants to join. Meeting up with some of the bundy hull crew at noon.

Also potentially going up to White cloud trail riding this Wednesday/Thursday.

Sorry somehow missed this until just now...White Cloud was great. I called my wife's boss (without her knowing) and got her a free half day of vacation, so we took a Wednesday afternoon off to go trail riding. Put in probably 30-50 miles over a couple hours, it was a good day.

Bundy was also a good time, it felt good to get back out there with the Jeep now that it's ready to rock. Also was a good time wheeling with a couple people I haven't ever wheeled with or haven't gotten to in years like Jake and Corey.

While at Bundy I also picked up my new to me 37s, so my 38s are currently for sale if anyone is interested.

Mounted the beadlocks today. Gotta pick up bolts for the raceline tomorrow. I’m hoping the one radial I have on an ATX will be swapped out for a soon to be repaired bias ply. It’s insane the difference in sidewall tread, the radial is non existent.

Tested out the new tires this morning. Amazing in snow and cold compared to my old ones. Pulled into the garage now to take care of a couple items before reject run.

Also I’m pretty happy that with no balance beads these tires still run 70mph down the road without issue, took a little trip to the hardware store.

Edit: ignore the POS radial on passenger front. Waiting on other tires to get vulcanized then that’ll be moved to a spare beadlock and kept on the trailer.

Put new springs in the rear yesterday. Went from 100/100 with 3” of preload and still sagging to 125/150 and no preload, Jeep sits level now. These were brand new springs I had sitting around, so I expect they’ll settle a bit and I’ll adjust the preload to compensate.

Great build and updates.

Is there a good place where people have documented what spring rates worked for them? I hope to go to coilovers down the road.

My junk =
YJ 5.3 / 4l60 / 231
Front = 44HP 3 link
Rear = 9 inch 4 link
35 inch tires
Mostly used for trails and the dunes.

Thanks

Thanks! And not exactly, but you can roughly calculate spring compression at ride height if you know what everything unsprung weighs. Or, slap on a set of springs you think will be good and if they’re not what you’re after, you can calculate from there.

No problem!

Same. According to my math, I should have only gained about 1.7” of ride height so I expect them to settle some. They definitely did settle after riding this weekend, but I didn’t get a chance to measure before tearing the front end apart.

Latest update tonight, I ported my stock power steering pump fitting from .150” to .190” at Kyle M’s recommendation, holy shit my hydro is 10x better from what I can tell sitting in the garage. There’s a few other tricks I can try, but this free mod was definitely worth it.

Hopefully I’ll be able to find out at reject run. I currently have a front shock on the way to Nevada and need to fix some rear suspension stuff after sliding into a tree at 30mph this weekend. But the goal is reject run at the end of the month!

The rear springs was a night and day difference, especially going across fields at 60mph. Hoping for the same change with my steering.

Psc pump is .172 and they recommend drilling to .190 if you need a little more. I have the fitting off my 6.0 hydroboost pump that is .168 or so, so I figured if the .190 on my stock pump is too much I’ll swap to my other fitting to choke it back down. The only thing I need to pay attention to is making sure the pump doesn’t suck dry at high rpm, other than that I should be good.
