2008 JKU "Argenta" Build Thread

[pc1p]

For me the YJ was the most fun to wheel (though not necessarily the best or most comfortable wheeler!)… mine was a ‘95, so it had all the fit and feel of a CJ, but with just enough touch of modern (EFI) to be enjoyable on hills and in the mountains. The leaf spring suspension, manual trans, and simplicity of it all made for fun line picking and finding the balance point while hanging tires in the air! It was the wooden rollercoaster of the off-road world: just safe enough to not worry, just rough enough to kick your a$$ while you enjoyed it

The LJ and even the TJ were much better wheelers and much more comfortable at the same time. Better seats, better dash ergonomics, an A/C, coil springs, etc. certainly made it easier to convince the Mrs. to come for ridealongs.

A few weeks back, I finally turned the heat on and the distinct smell of mouse pee/poop came out.

A bit different environment but I just got done riding my shed of mice "evidence", sealing all the entry points, cleaning, disinfecting, and painting. We'll see how long it lasts! For such small creatures they sure leave an impact.

Mine was a 87, first year. It had a carburetor, which was a pain. They had to fix it three times under warranty. Then it was fine just difficult at time when off roading.

Mine was a manual as well and much simpler to work on, very basic. The LJ is a 6sp too.

I think the TJ / LJ are a nice break between the CJ and JK. Better suspension fuel injected etc. But not too many electronics. The LJ doesn’t even have ABS, that alone made me smile from ear to ear.

Now the fun begins…

It’s a 2010 5.7 Hemi with ~108k miles. Ran strong when running, came out of a wrecked truck. The PO said it had a check engine light for cylinder 8 misfire, but it ran fine and had great compression.

I’ll pull the heads and give it a once over, likely replace the cam and lifters while I’m at it (maybe even drop in something with a little more zing). The engine came with everything, p/s, alternator, a/c, starter, PCM, harness, etc.

Got to working on getting the housing stripped down a bit and prepped for welding the truss. The first step was to matchmark the carrier caps to the housing, then remove the shafts and carrier:

After that, I turned my attention to removing the vent hose fitting. Note for anyone needing to do this, you’ll need to completely remove the adjusting collar as the hole is covered up (see red arrow):

A few quick whacks with a long punch and it popped right out:

The hole that the fitting is pressed into is just about perfectly sized for a 1/4” NPT fitting. I’m gonna run a 7/16” drill bit down just to clean up any edges, but it’s probably not required.

Should have this all done this week, which means I can weld the Artec truss in place this weekend.

Also this weekend, I’ll be picking up a brand new in box Gamechanger 3.5” lift kit from someone about 2 hours away (we are meeting halfway). I already have the 2.5” Dual Rate MetalCloak kit, but wanted to get the full set of arms and rear track bar, and a set of 3.5” springs. I was waiting on a Black Friday sale, but for $2000, this is basically the same $$ I would be spending, plus will let me save my 2.5” lift for Charlotte’s Jeep next year (which will also get my current axles with a fresh regear, and a set of 35”s).

Got the engine pulled off the trailer and started to get it prepped for a proper cleaning...

I ordered an engine stand from AutoZone.com, mainly because they offered free "next day" shipping and a 20% discount code. Of course, "next day" turned into "next, next day", so the stand won't arrive until tomorrow. In the meantime, I guess I'll stop by the hardware store and get some clean 3/8" Grade 8 hardware so I can get this mounted when the stand finally does arrive.

While I'm waiting to make the next step, I guess I should get back to working on my spigot installation at the front of the house. At least I'll have hot and cold water when I finally am able to get the power washer fired back up again...

 

[pc1p]

Two hours of sweating pipes together and I finally have a spigot in the front of the house!!

Not only a spigot, but I plumbed both cold and hot water to it. My original plan was to install two spigots, but due to space issues on the exterior wall, I decided to simply run a single spigot with two water feeds. I can keep the cold water open, but when needed, can open the hot water supply and have 145° water right at the tap...

And let me tell you, it's amazing! Even just rinsing the motor with hot water got so much grime cleaned off. A few sprays with Simple Clean, followed by a proper power washing (also using the hot water!) and the motor is squeaky clean now! I'll wheel it to the back of the garage, pull all the plugs, spray in some fogging spray, and likely pull the intake. At that point, I'll wrap it in a tight bag and there it will sit until I'm done building the 14-Bolt and get the lift installed.

On Saturday, I made a trek up to Binghamton to meet the guy selling the 3.5" MC Gamechanger. Everything is complete and transaction went smooth... this will go on the storage rack, while I'll be pulling the current 2.5" Dual-Rate kit down and getting that installed in ~2 weeks. I'll be in Tampa this following week on a work trip, so nothing will be happening this week, but I may find a few minutes to order my 14 Bolt gears and install parts one evening.

Good solution!

Good solution!

I had to keep the valves tucked under a crawl space area, but it's relatively easy to get to and they're protected from damage, so overall a good solution to get me what I didn't realize I needed so much in my life! Hot tap water from the hoses may be the best thing I ever thought of before... lol

I got back from my work trip to Tampa and decided to take a few days off of work to get the Metalcloak lift installed. First up was double-checking my inventory and then pre-setting the arm lengths according to the MC instructions:

New Crown bump stops since my fronts are totally missing and the rears are crumbling apart:

It took me a good bit of time to do the full install by myself, at least much more so than I thought it would. Truth be told I'm past the 40-year old mark and am slowing down a bit. Plus, I stopped a few times to run some other errands and get some stuff done around the house. I also spent a good bit of time cleaning up the frame and undercarriage. Here it is after some wire wheel and air needler work:

Nothing major again, but it did add at least 3 hours to the total install (for both front and rear) as I took my time and did a thorough powerwash and dry before applying rust-converting primer and paint. Aside from the two front brake lines (going into the hose) that did not want to rotate (I had to "twist off" the hose and reinstall the new MC hoses the same way!), the install went incredibly smooth.

The only major unexpected thing was when I was installing the springs. A lot of people say you can install these springs without a spring compressor. I didn't feel like disconnecting the speed sensor wiring (worrying about damaging it, given its age) or pulling/hanging the calipers, so the compressors certainly made life easier:

Thankfully there weren't any rust or corrosion issues that prevented disassembly. Overall, I got to the point of bleeding brakes and centering the steering wheel after about 11 hours of total work.

After the first test drive, I'm really happy with the set up! I no longer have to bite my teeth together to brace myself when coming up the driveway, or going down certain roads waiting for the suspension to bottom out. I was worried that the 2.5" springs were going to look like I skipped leg day too many times but overall I'm not upset with how it looks in the short term. The backspacing on these wheels help push the edge of the 285/75's out to the edge of the fender flare, and their slightly larger size helps a bit. It would look better with a set of 35"s slapped on there, but such is life She'll be wearing a set of 37-38"s soon enough (once I swap the axles this spring), though if I find a nice set of 35"s, I would consider doing a short-term swap (again, these wheels are likely going to my daughter's rig when I'm done with them).

I hear you. I probably have 10 years on you and just did all the shocks & springs on mine. I just took my time, didn't rush, or beat myself up. When I was younger I was quicker, but dumber in some ways too!

Yeah, that’s really the only way to do it… I’ll probably set aside a week for the axle swap, spending a lot of time upfront getting the axles in so I can measure for driveshafts, then taking my time getting it all buttoned up, checking clearances, adjusting arm lengths, etc.

Thankfully I get unlimited vacation time, and being an Elder Millennial, I put it to use

Decided to check the toe and tweak the steering wheel centeredness:

Toe looked off a tad but was dead on with 1/4” toe-in so I didn’t touch it. I did a slight tweak on the drag link and the wheel is dead straight and drives perfectly centered down the road (on top of the crown of course).

The Mrs asked if I would run some errands, so I spent the better part of two hours driving around, up and down country roads, through town, over railroad tracks, and nearly everything in between.

The handling and ride are great. It will take some time to get used to how tight and responsive the suspension and steering are now. The worn bushings and sagging factory springs made for a supple, but unresponsive driving experience.

I picked up a new Duralast 34-DT battery to replace the economy brand battery in the Jeep now. It’s not acting up, but I don’t like how the terminals are crossed (the current battery has terminals on the opposite side that the factory Jeep terminals are), and I want to get my Warn Zeon 10S installed soon. I’ll keep the current battery on the trickle charger and have it as a backup through the winter months.

Yup, I hit that at 40, was good for 15 years or so. And now it seems like I hit another “slow down” the body can’t do what it used to do.
