Glad everything worked out good. My weekend was similar.

I’ll toss another post up here although I think the ‘build’ portion is finally drawing more to a close. After the prior shakedown I was lined up for a more legitimate run with a local club. In prep for that I ditched my super quick, super crappy skid and threw together a much more legitimate one. Still wasn’t terribly fancy or good looking, but it’s light, strong and easy to take on and off. It bolts to the frame covering the t-case, then bolts to brackets I built on the trans cross member. It hangs down no lower than the transmission crossmember so I didn’t lose any ground clearance. I’m 17” to the belly pan, not the best, but to do a true flat belly skit would require much more work than it’s worth right now.

I also got a cab radi installed, tilt the antenna mount from angle iron, works like a charm.

Then it was on to wheeling. We ran a trail called hanging tree and it was rad! We’ve had super heavy snowpack this year so while this trail is supposed to be mostly dry it was basically driving a river. Lots of big boulders, ledges, off camber stuff and waterfalls.

Sadly, we didn’t get to finish. We had started too late, with too large a group and had too many breakdowns. I think we had 1 flat, 1 lost bead, 1 snapped rear shaft, one snapped front shaft, one Jeep that died mechanically and quite a bit of winching out stuck vehicles.

As a better evaluation of the more finished product I am happy to report it does excellent. Flex is adequate, clearance is good but I’m really happy with the stability. Even in really off camber spots I never felt it was about to go over. The only time that happened was when we turned around on the trail, I drove up a near vertical embankment, at an angle, she started to go, but I was able to quickly back out of it.

I also retract my prior assessment of the motor, it seems to have plenty of power down low, the motor never lugged going slow up anything at not much more than idle. Also the fuel delivery seems spot on, it never choked and even when I killed it climbing a steep stair set it started right back up.

Now I’m hungry for more though and feel very confident in this jeeps ability. I also like the wheelbase, it was great for the tight quarters we were in on this trail, I’m sure on others longer would be better, but for this still it was great, o was able to easily maneuver over and around stuff where others really struggled.

Now to build a little more armor and get back to finish this trail!

Not sure if it’s even worth adding this, but why not! I decided to make a small change due to my steering interference. My drag link end rubs against my tie rod just a little so I decided to upgrade to the parts mike pitman arm. It’s flat, un-indexed and beefy as crap. This will also help since I’m currently using actual drag link ends and didn’t realize the wagoneer pitman is setup for tie rod ends. This explains why they wouldn’t go in deep enough to get to the cotter pin hole no matter how tight I went.

I need to ream to steering arm to account for this as well, but then my drag link should be perfectly parallel and there should be no interference. Hoping to get some seat time again soon, things have been a bit crazy so it hasn’t happens since the last trip.

So I figured I'd touch in here because lets be honest.. A jeep build is never really done. and because we build these things to find their limits. Well it seems I found them on mine. I've been wheeling it pretty hard all summer with good luck, hadn't broken anything until last weekend, then it all went south. We went out to Sand Hollow UT (look it up, its sick) wheeled for a day and a half with no issues, then on a really fun obstacle I got bound up when I slipped into a V-notch. tried to drive out and 'SNAP' front driver shaft ripped the ears off and blew the u-joint out (it actually shot out and hit my buddy in the arm, looked like a paintball welt).

Then things just went further downhill. on the same notch I had also smashed the side of the rig which shattered the side mirror and crushed a fender. I didn't realize till a little later that this had also deformed my battery tray and tossed the battery free and onto the engine, scary since it could have caused a fire. Then I randomly popped a front braided brake line, and after hobbling through another trail in 3wheel drive i randomly blew up my rear driveshaft.. the cage just kinda gave out, blowing the u-joints and rendering me 1 wheel drive (kinda). after some sketchy towing down sand dunes and on the freeway I trailered it home and found that to top it all off I had actually bent my driver side knuckle, leaving the ball joint completely free from its press fit.

So.. back to the drawing board.. Kinda, overall, the construction of the jeep has held up well, however, I had not yet sprung for the upgraded internals and apparently externals that cant really be built. additionally, there are things about the performance that leave much to be desired. Primarily, the rear being leaf sprung with a stout anti-wrap bar creates more of a jacking motion than I had hoped, it likes to hop like crazy when its trying to find traction. Also, the wheelbase could use a little more in the back. SO.. the plan is this:

For the front. Upgrading the knuckles to Reid racing HD knuckles, planning to also get Chromolly Ball joints from Parts Mike and looking at Chromolly shafts with 760 u-joints from ECGS as well as having some new brake lines built. I had considered going to Tons, but the reality is the jeep would be down for well over a year with saving and building, and my plan for the forthcoming years does not go above a 37" tire so it seems unnecessary.

In the back, as simple as the leaf life is, I don't get the flex I really want, even with the soft YJ leaves, so I'm working on going to a double triangulated 4link using the Barnes4wd joints. I'm planning to use stock TJ rear coilsprings and go with a 14" travel Bilstein to match the front. I considered air shocks, but really I think that coils will be fine for now and will be nearly free compared to another 5-700 for decent airs. Coilovers are way out of the budget for now. Conveniently I actually have a spare driveshaft that is just over 3" longer than what I had in there, so I'm also going to take the chance to pull the back end out that distance. Hoping to land right at 101" WB. This will save me having to buy a driveshaft in the meantime, but I plan to go up to a 1350 shaft once funds allow it and keep this one as a spare.

As time goes on I am also going to re-do the cage to something more appropriate to my wheeling style (read: I don't care if I roll it, as long as I can drive away alive). I actually bought a real tube bender just before all this crap went down and ended up going on this trip instead of picking up tube as planned. But that can be done over a week or 2 any time of year.

Finally I've also decided the spool has to go. Its predictable, but its also a pain, its hard on the tires, hard on the axle shafts, hard on the driveshaft and just chirpy and obnoxious in most places. So I am planning to go with a proper locker. Id love a selectable, but I may just go with a detroit. Either way, that's also down the road when I can get my money tree to blossom!

and second finally.. I also plan on going to 37's with aluminum beadlocks to keep the rotational mass down.. but that will probably not be for a year or more and will also probably have to come with hydro assist.. I think I may have a problem lol. As always, if I write it down here then I have some accountability.

Wow. In for a penny, in for a pound!

You certainly did not go half way with the carnage, Tanner. Looks like a great trip regardless. Looking forward to following phase 2.

Or is it phase 3?

Haha, hey I still had a good time, we all know you have to pay to play though. That said, I definitely jumped in with both feet. Even still, things broke in the most convenient places to minimize danger and make extraction super easy. brake line burst right at the start of a big sketchy climb, would have been really bad if it burst at the top. Driveshaft went out at the top of the sand dunes right above the parking lot, short downhill tow over soft dunes, easy! For all the damage done, it didn't even put a damper on the day, we just towed me to the bottom and hopped in with a buddy and we wheeled the rest of the afternoon.

Not sure what "phase" this qualifies as, its all just a rolling money pit. Fortunately I don't anticipate this being as time intensive as the work I did last winter, and I am happy I got most of a full season of wheeling out of it before she went down. The bigger issue is getting the cash together to do it all. I don't get into debt on this stuff so it might be a minute until the money tree gets a few more bills to pluck off. I feel it will be much improved though if I do a decent job linking the rear. Saving also gives me time to measure and get all the angles right and build mounts and what-not so that when I pull the trigger on everything I can probably knock the links out in a day. Kids seem to eat up all my jeep money haha.

Yeah.... doing what we do with our Jeeps, we have to be prepared for these things. I hear you with the money tree. They just never seem to grow fast enough.

So the smart thing to do would probably be to fix the front axle, have a running Jeep, then work on the rest as time allows, but I’m not smart. So.. I’m jumping into the 4link with both feet!

Since this is the first time I’ve done a 4link so I’m studying up lots, but the ultimate plan is to build a removable crossmember that will hold all the frameside mounts, that way changing it is easy if it doesn’t perform the way I expect. I’ll also make the upper links adjustable.. of corse I’m too cheap to buy the brackets, but I have a small stash of flat stock to build everything with.

To make sure I can’t back out of this I made my first purchase with some artec goodies. Bout time too, I could literally hit their building with a golf ball from my house, but I’ve yet to have anything from them on my Jeep.
7b97d96d-cc71-4b32-8663-1f297fe52a9f_1570762562700.jpg

I started taking the easy stuff off last night like the anti-wrap bar, shocks and skid plate. I don’t have much of a rush on this since I have to get cash together for the front axle before I can use it anyways, but progress is progress. Getting pretty cold here already anyways.

Only thing I’m trying to reconcile is the space above the axle is kinda tight. I only have 6.5” from the top of the truss to the bottom of the fuel skid. I really don’t want to relocate the fuel cell so I’m considering putting the links either slightly more off to the side of the truss, or a little more recessed into it, gonna have to do some measuring to make sure I can still get all the geometry right if I do that. Gonna take some fiddling.

Small progress, but all moving forward. I pulled the axle out, sold my shocks and the anti-wrap bar so that’s good. Set the height up about how I expect it to be at ride height and did some measuring.

Axle out

The trailer I bought came with a spare driveshaft that is perfect for this change, spent a minute tearing it down for rebuild

Since the old one looks like this...
f1ee3ef9-c83f-41bd-b910-c5a1d7d6eafe_1571099185179.jpg

Picked up some used TJ rear coils. They should sit at 8” with weight on them.
adadc22f-86d9-4c57-abc9-1ef05168f730_1571099245569.jpg

Cut the spring perches off the axle.. guess my welds were good because it sucked. Then made some cardboard templates for the lower link mounts.
cade8307-4fae-4345-ab5e-7a6aac7579ec_1571099278447.jpg

Then made them from steel. Turned out good I think.

Here’s the rough measurements (if you can make sense of my acronyms.

Computer wasn’t at home so I can’t put them in the link calculator just yet, I’ll do it tomorrow. Still have to make the frame crossmember and figure out the upper axle mounts. Moving along though.

Lots of pics, less words for this update. Long story short I built the crossmember for the frame brackets.. and the brackets. Sometimes wish I wasn’t too cheap to just buy things, but oh well.

Started by bending some brackets that bolt to the frame rails, then did what felt like hours of drilling to line up the holes since it was too long for any drill bits I own. Then drilling the frame, then cutting tube to sleeve it for bolts. No pics for this, it wasn’t exciting, just messy. Oh, and cutting the old crossmember brackets off too.

Then lots of plasma cutting, really could use a CNC table.
3044ee48-5ab5-4d76-baeb-62e4d2ace095_1571441421512.jpg

Got the upper axle brackets made.
779e167c-f338-4865-8763-1bbb8819cf19_1571441439893.jpg

Then welded the cross beam for the crossmember on.
1f3f1584-a631-4fa8-8227-40e782db3991_1571441463646.jpg

Bent back plates for the link brackets, racket them up.
bdeccf90-e828-4e33-85e5-186197087e08_1571441485270.jpg

Made a jig of sorts to keep the spacing correct got finish welding. Worked great!
644fe4f6-df7c-4649-be27-019369621ff4_1571441538477.jpg

Then I did lots of measuring and setup. I wanted to be able to get things lined up perfect and figured it would be easier out of the vehicle so I could stand up. I mocked up the crossmember where it will be on the Jeep and the axle and so forth, basically replicating the final setup, but off the Jeep.
4d66f004-bcc0-432c-8a9e-7c19d63dd23c_1571441562175.jpg

Worked great, got everything mocked then tacked
5ebcc044-3f9d-41d7-8ac7-4c493dbb11ec_1571441585349.jpg

Then I went to town, really winged it, but I had an idea what I wanted. Lots of cutting, grinding, drilling and welding.
41f2612c-19e3-411f-ba01-aa15cac97253_1571441658852.jpg3c847145-76a8-4dce-9337-61fa4fe72502_1571441630774.jpgd1d7edd9-0190-4ec4-a7a8-23398669af10_1571441604041.jpg

And that’s where I stopped today. I still have a few more things to do on this so I trust it. The center tube is only .120 wall, but with all the gussets and the .25 backbone I built I think it will be plenty strong. Once that’s done I can paint it and move on to the axle then the home stretch.. unless I end up cutting the fuel tank apart that is.

Little wrap up to yesterday, spent some good time finishing this mostly up. Cleaned the edges up, rounded corners, added more bracing, covered holes and whatnot, then test fitted the joints. Little tight on a couple, but not bad for all the heat I’ve put into this thing.
18b526e6-fd8d-426b-84d8-ee995f21ef26_1571533612782.jpg

Then test fit in the Jeep to see if I warped it terribly or had measurements or clearances wrong. Happily all was well. Have to widen 2 holes a hair where it mates with the frame, but it fits and it fits well.

I can adjust the frame side separation from 3.5” to 6” with the 3hole upper bracket. Pretty stoked on this. Now the less glamorous job of cleaning up the axle!

That turned out great. Adding a skid from the trans cross member to the lower link gusset will strengthen it even more and smooth the belly.

Thanks, and you read my mind. planning to add a skid between the 2 crossmembers. Would be nice if I could do this as a true flat-belly, but it just Isn't practical, pus I still have 19" to the bottom of the skid so clearance has never been much of an issue.
