No problem.

So the full size fairlead holes line up exactly with the winch mounting holes. for mine what I did was get some high grade stainless bolts and cut the heads off of them to make redneck all-thread (since I couldn't find high strength all-thread in the size I needed) i used those studs to mount the winch by threading them to the winch on one side, then using a locknut and washer on the other side. I was then able to flip the fairlead over so that the recessed portion went over the locknut while letting the stud stick out. This let me mount the fairlead flat and use a nut on the backside of it to hold it on. I would imagine using an ATV fairlead would work great though so you dont have to go to all that trouble!

tbunch Decided to get off my butt and do a little more today and wrapped up the suck down winch.. mostly.

Used some old tabs and some 1/2” I’d dom I had around and made a hookup point on the axle. Welded and painted it up.

Attachment 3922823

Everything is so tight I don’t have room to use a hook in there, not really a big deal, I’ll just use shackles or Lee’s couple hooks in the recovery bag.

Here is the fairlead setup under the winch.
Attachment 3922821

Everything clears nicely, very close though. At full lock I’ve only got about .25-.5” clearance to the ram, but nothing rubs. The winch line doesn’t run anything either.

Need to hardwire a panel switch in the cab for it now. I’m also thinking I need to cut down the front bump stops, they seem to be much too long and when I was running dirt roads last week I could feel them constantly. Air bumps are definitely in my future.. and some valving.

tbunch Ok, I think the steering is finally fixed.

Spoke with redneck ram guys and we concluded my pump had either failed, or at the very least was tired. It has 170k miles on it and I didn’t do any mods to it.

So, I got a brand new pump, pulled it apart and modified it for flow and max pressure.
Attachment 3922639

Then proceeded to bleed it for honestly 2-3 hours. But at the end of all of it I still had no right hand steering with wheels on the ground.

Another talk with redneck ram and we whittled down a couple possibilities, ultimately it appeared the spool valve in the gearbox was having issues.

Fortunately I have an autozone reman box that means I have a lifetime warranty on it, quick call, had it in stock, 10 min to pull the old one and they took it without questioning the 2 large threaded holes I put in the side of it, score!

Downside; now I had to re-drill and tap the box. Luckily it was simple. I went exceptionally slow this time and spent more time with a much smaller magnet cleaning the holes. I have a suspicion that the box could have failed from a piece of metal finding its way into the wrong spot and clogging things up. I also had a suspicion I may have blocked the passage on one side by putting the fitting too deep. Not this time.
Attachment 3922641

Installed and bled it out very thoroughly, and added a small steering cooler while I was at it.
Attachment 3922645

Everything seems to be working! That tends to happen when you replace the entire steering system..

I had a chance to get out on some cool trails today, but I passed it up since I hadn’t tested the steering formally and didn’t want to be the guy dragged off a hard trail because I came before I was ready. Soon it can have its true maiden voyage!

Congratulations. It looks like it did great. I have been learning mine as well, pushing a little further every time. I have also learned that my steering is becoming a problem. I just got a cooler yesterday that is going to work well and have been looking at the West Texas Steering Mod. I have to pull my pump due to the brackets so I haven't dove into that yet.
I’m excited for its potential for sure, and to get out and start using it.

As for the steering, I think I have the solution. I spent some time on the phone with West Texas Offroad (redneck ram), and we discussed my setup. I also spoke to some buddies and the guys at poly performance) the consensus is that my pump is the weak link, along with the lack of a cooler. My pump is the original from before the motor rebuild and as such it has over 170k miles. Add to that the fact that it’s not been modified for flow or pressure and you get a serious weak link. I was able to wrangle up some cash by returning bits and pieces I haven’t used on the build and I have a new pump I’m picking up today. Once I do the west Texas mods and add a cooler the thinking is it should work perfectly.

The only drawback mentioned is that with the large ram and big bore steering gear I’m running my steering will be slow, on the flip side, if the pump works as expected, I should have gobs of steering power despite low speed. This also shouldn’t matter since the majority of my wheeling is technical crawling and this isn’t built to go fast.

On that note, I will at some point need to re-valve my shocks. The valving is not right and while it handles great in the rocks, it’s not a very smooth ride. If I hit larger bumps/dips at speed (speed being like 25-30mph) it bottoms out hard and it’s very rough.. anothe breast for another day.

Also going to try and adjust the pushrod on my master cyl to make sure I’m getting full compression on my brakes.

Little bit at a time.

tbunch Well, success with a small helping of failure. But not to worry.

First things first. I had some good help this week from buddies ready to get out with me. We buttoned you small details like harnesses, painting some things, tuning the springs a bit more and just little things, one of which was discovering that I wired my fuel pump backwards.. for pretty mad since I thought I had a bad pump... stupid thing really.

I was able to go on some street drives with my buddy and took my 3yo daughter on a cruise around the neighborhood since she has been anxiously waiting for daddy to finish the Jeep!

In the midst of all this I ordered my self a little gift for getting to this point.
Attachment 3921249

Finally ditched the steel cable for safer rope. I justified it because that little side project is making my winch dual pull so I have a suck down. Cut a hole in my bumper plate and with the help of my buds we fixed a hawse fairlead on it. I still need to weld the attachment point to the bumper and hardwire controls to the cab, but it will work nicely!

The verdict so far: it flexes like a beast! The pictures don’t even show it, but it just drops those tires down all the way! And it keeps traction so well. My buddy is pretty hardcore, but very experienced and he put me right into time tough spots and it walked most everything.

However, I need seat time badly! The Jeep drives and feels so incredibly different than it did on leafs. It’s no surprise, but actually feeling it is eerie. Looking at the pics I can see where I was stable as ever, but it felt like I was going over constantly. I really don’t know it’s limits yet and I don’t know where my tires are, it definitely had my nerves up, but once I get familiar with it, it’s gonna be able to tackle some tough stuff!

Other thing is that the suck down winch will be very useful. In truth, the front suspension doesn’t unload as much as I thought, but if I’m climbing something like a ledge it does go up before the wheels climb. As a point of confession, I can’t actually climb onto my trailer. The body jacks up enough and the truck moves enough that it just doesn’t want to do it. Not a big deal though.

Unfortunately our fun was cut short due to shortcomings with my steering. Midway through a pretty tough obstacle I lost basically all steering to the right. At the repeated advice of several hydro assist retailers I was convinced I didn’t need a PS cooler. I also hadn’t modified my pump at all and am using a 2” ram. All effects combined to my steering fluid boiling over and everything stopping. We limoednit back to the trailer and I got it back to the garage for another day.

My friend gave me a good sized cooler to use and I’m going to try modifying my pump. If that fails I’ll have to save up for a higher volume pump, alternatively, my other friend has a smaller PSC ram sitting there that might be the correct throw, but require less fluid to move. Since I’m ultimately now out of money I’m searching for the cheapest solution.

In all I’m excited, steering being the only failure, and one I half anticipated, is acceptable.

My brakes need some work also, try as I may, the pedal is still soft. There is likely still air in them, but I’m starting to suspect that’s may have too short of a pushrod for the MC I’m using. All research says no, but I can’t help feeling it’s not compressing things all the way. Gonna sit on everything for a day or 2 To build up some energy to get after it again.

Very exciting though!

Haha, it’s definitely felt like a long time in the garage, long as it’s all worth it and it works like it should I’ll be happy!

It’s very close though. I’ve put in some hours yesterday and today to get the sway bar knocked out. It was more work than anticipated, but I’m pretty excited about it.

Placement was a bear because I had not designed anything with a sway bar in mind, love and learn I suppose. Issue was my slider lands exactly where I should have had the tube go through the frame. Can’t go in front or it will hit the coilovers, below hit the links, so I was able to barely squeeze it in on top of the frame.
Attachment 3920319

Doesn’t look like much, but I had to cut the edge of the tub and then spend all night cutting little bits off the bottom of the tub, take the whole fuel system apart, eat a mournful of dirt and the bar juuuust fits. Some Oates that weld to the frame on both sides and it’s quite stout! Mocked up the arms just to see.
Attachment 3920321

It does have one drawback that I will lock myself for later.. the bar cannot be removed.. my frame tie-ins are directly in the way. I played with it as much as I could, but there was no way to make it happy. The back of the arm hits if I go forward, front hits if I go back. Hopefully it just stays on there forever and never fails... maybe?

Anyways, today I welded it up since there was gas everywhere yesterday, painted it up and installed the arms for real.

Also knocked out the rear limit straps. Been waiting for 18’s, but they are in back order from PRP so I made 16’s work.
Attachment 3920323

Not perfect, but they will work. My bump pads are too big to put them directly in line with the shocks.

Tonight I made the links and welded tabs to the axle and got it installed and back on all 4.

Attachment 3920331

Pics are a little dark, but you can see how it all fits. It’s basically textbook. I have 16” shocks so I got 16” arms, it’s perfectly level at half shock travel, links are 17” eye to eye and the tabs on the axle are just a little wider than the arms.

I need to play with it a little tomorrow and probably preload one side so it better resists the torque lean, just try and get it down.

Basically just the little stuff left. The plan is to get it on dirt on Friday to get some real world testing done. Quite excited. I have one more little side project to knock out that I’m pretty excited about, I’ll share that if it all works out! Extremely close now!

tbunch Got a couple more pics of the exhaust, not great pics, but it’s something. I need to have it coated or painted with header paint since it’s not all stainless.

Then I also got this package of goodies in the mail today!
Attachment 3919989

Pretty stoked to get it in and see how it changes stuff. Hoping this one is enough, if I have to add a front one I can do so once the funds have rebounded.

Unless I run into some major complications I should be ready to do some trail testing this weekend. Not gonna go if things aren’t ready though.

tbunch Thanks coggsdsmt

So I’ve here’s kinda where I’m at. I’ve spoken at length to the guys at busted knuckle, the folks at accutune, my local fab shop and some buddies and have come to a few conclusions.

First and foremost, I need a sway bar. There just isn’t an easy way around this one. I spoke to Tony at TK1 racing and settled on a 42” rock crawler bar with 16” arms. And pulled the trigger. He was pretty convinced I didn’t need the double shear kit for my setup. Hopefully it comes soon so I can get it in and really do some testing.

Then there is the ride height. I got all kinds of suggestions on this, from moving my mounting locations, to changing to 14’s to running tender coils, several different spring rates and heigh calculations. And so on.

To rule a few things out I re-measured and re-ran all my measurements through the 4 and 3 link calculators. This let me see if there were any glaring link geometry issues that needed to be resolved. Fortunately the numbers looked great. I’m at 84% AS in back and 89% up front. And my roll axis angles are not bad, -1 in back (perfect) and 4.3 up front. The front will contribute to oversteer and body lean, but not by much.

So what I have done for now is this. I went somewhat against the grain and relieved much of my spring preload. Currently I have about .25-.5” of preload on all the springs. It’s definitely lower than I should be running, but it accomplishes the ride height I need and since my axles have limit straps I don’t think I’ll ever be in a situation where I don’t have more actual downforce on the spring than just the preload.

I have also lowered the adjuster nuts to an inch above the slider so that the dual rate comes into effect sooner. Easy to change if it’s too soon.

In all I was able to lose just over 1” on ride height. And it’s honestly about perfect. When I get in it it still leans, but only 1.5 degrees. Not terrible. I’ll probably add some additional pre-load on the driver side just to hold it level when I’m in it alone.

Other things to do eventually is change the shock valving so it has better control. I can also go with a tender coil in the rear and use slightly heavier springs which will help more with lean and load capacity. For now though I’m going to try it with the sway bar and see where I’m at.

This is a more tedious process than I thought, but I want to try and do it correctly. In reality I should have used a 14” coilover or air shocks, but live and learn.

On the plus side my buddy gave me some nice LED headlights he had from an old project that will be a nice upgrade to my old ones!
