'89 R3500 Crew Cab 2wd to 4wd conversion & beyond

Started out with 2wd TBI350 with SM465 to current 4wd with 454, 700r4, NP241
Finished the fluid box which also became the home for the rear battery switch. I opted for a somewhat weather tight design. I do have future plans to put a flip-up cover over the battery switch. I ended up really boxing myself in when it came to getting the box riveted together. I was having to drill the holes blind from the inside, so there are a few errant holes and rivets. :doah:

The "door" drops in. It pushes up under the top and then drops down a little behind the bottom panel. A single screw holds it in place. I lined the inside with pieces of oil absorbent mat. I mostly wanted something to pad the bottles a little. There are 8 quart bottles, 2 pint bottles, and a can of brake cleaner.

I also finished the cargo rack.

The slides are supposed to be rated for about 400 pounds at full extension. On the way home I was telling my son we should have had him sitting on the rack for the pictures. The reason I added the slides was to have access to the spare tire without having to unload and remove the rack. It's all made with aluminum except the slides which are actually quite heavy.

I can walk under the rack when it's extended but anyone pushing 6' or taller will have to duck.
That’s cool. Now you need to make it tilt down to the side for easy access!

Yeah, I was thinking it needs some elevator action.


I assumed you were going to put one of these on it, you know since you're an overlander now! :D

Actually I was thinking it could be easily adapted for an awning.

I'm hoping someone will donate me a free set of traction boards I can mount on the sides of the frame. At the very least, my Hi-Lift might end up there.
 
I forgot to mention when I was doing the wheel bearings, I figured out both of my tie rod ends were loose. I had a tire off the ground and I grabbed it to pull myself up and it moved. Turned out the tie rod was loose at both ends. re-torqued them and they are good. It's catching those kind of things that I think is a big side benefit to doing maintenance on the truck. I've often found similar issues in the past.
 
Oh and I've been noticing on the trail there was slop in the steering column. I could kinda feel the steering knocking back and forth, if that makes sense. I thought maybe it was a bearing in the column or something. I found where the Borgeson shaft u-joint slides onto the steering box was loose. I snugged up the set screw and it's good and tight now. I was reviewing the install instructions for the Borgeson and it mentions re-tightening the set screws after the first 100 miles or so, and I'm pretty certain I never did that. :whistle:

Be interesting to see how the steering feels on the trail.
 
Some crew cab updates.

For those that missed the Rubicon thread, we made the 2,300 mile trip driving the crew cab all the way there and back without any issues. There are things that need addressed, but nothing that stopped us from getting there, driving the trail, and making it back home.

Here's the cargo rack loaded up for the trip:

Here are a few trail pictures:

This was a water crossing that I tried to drown the truck in. There's a deep hole if you cross too far to the driver side. Jerks watching from the shore were yelling bad directions at me and it got deep enough the rad fans were spraying water out the hood vents.

Luckily @Imaginary Friend 1985 got me pointed in the right direction but it's still plenty deep.

On the way there we had to stop at my favorite speed shop and get a picture out front and do a little shopping.

As for the bad, the first issue was airing down the front tires a bit too much. I ended up burping the bead a couple of times which has never happened before. So I ended up airing them up to a little higher pressure. 11psi versus 14psi. Didn't have a problem after going to 14psi.

I hit the front axle and diff cover a lot on this trail, more than I can remember on any other. It was bad enough that @ashman and I both had to tighten our cover bolts because the bolts had loosened up from the impacts.

You can also see in the picture above, the front shaft got a little love. Also evident in the picture below.

I had 3 problems with body damage. The on the last day I noticed one side of the hood seemed to sitting up higher than it should be. Turned out I had ripped the hood pin out of the core support. Coming down a drop off that required turning and avoiding a tree, I got too close to the tree and dented both driver side doors pretty badly. Luckily no glass was broken and both windows operate normally. The last problem was scaping the passenger side 3+3 badge off.

On the way back home, we took a quick detour to drive on the Bonneville Salt Flats. It was a lot of work to clean the salt of the bottom of the truck once we were home, but it was worth it to say we've been there.

I was only driving 75mph, which is just 5mph higher than I drive on the interstate on the trip there and back. I was thinking more about how I had 8 hours drive left than trying to set a land speed record.

Since we got back I've been working on finishing a project I had to abandon before the Rubicon. I had hoped to get a rear winch installed before the trip, but in my rush I messed up some of the mounting holes and I knew there wasn't time to get it done. It's mounted behind what passes for the rear bumper.

The plate is bolted to the lower angled piece. I knew it was going to be a tight fit, but I had hoped I could lift the winch into place without pulling the lower piece. I didn't quite fit. I still ended up needing to cut notches in the rear bumper area to get it in place.

20230729_143648.jpg

I added pieces of angle that were also acting as washers. This is because it's the mounting holes for the winch that I had messed up drilling them at 4" on center instead of 4-1/2". I had to make slots in order for it to work. I felt like the angle gave me a little piece of mind with the over large holes.

20230730_174035.jpg

I would like to say I had intended for the winch controller to fit on the back end of the plate, but that was total luck. The plate only sticks out that far because that was the size of flat plate I had laying around the yard, 12" wide 1/4" plate. One of the reasons I abandoned the project before the Rubicon was because I expected it to be a lot of work to mound the controller somewhere.

It is possible to reach the clutch lever from behind the truck without having to try too hard. My intent is for it to always be engaged and power out the winch line. I'm using the wireless controller to run the winch with a remote.

20230730_174122.jpg

The winch I'm using is my Tabor 12K that had the burned up winch motor from a coupel of years ago. I found a company selling replacement motors for half the cost of a Warn replacement. I figure it should be good enough for a seldom used rear winch. I'm also using an old synthetic line I had to cut about 15 feet off of because it got too hot and melty on the winch drum. The wireless controller is also an old one I had for the Tabor winch. I wasn't using it anymore because the Warn Evo winch I have up front now came with a wireless controller.

I like having the Tabor winch back on this truck because it has a little sentimental value. My dad had given it to me a few years before he passed. That was when I still had the K5 so it's been with me for a while. In the meantime I've had to replace the tie rods and one end plate, plus a couple of contactors, and then finally the motor.

Now that the winch is in, I can start working on making use of that cutout in the lower piece of the rear bumper and get a receiver hitch installed.
 
What did you end up for fuel economy on your trip?
I was using 8.5mpg to figure my range since I've never gotten the fuel gauge to work correctly. That seems to be the fuel mileage for local runs. It must have done better than that because I wasn't having to put as much fuel back in when we stopped based on travel miles. I don't think it was getting anything better than 10, but probably something in the 9's. When I start pushing the speed over 65mph, the fuel mileage suffers. But who can stand to drive just 65 when the speed limit was 80 for most of the drive.

I can tell you we spent over $1,200 on fuel for the entire trip. :yikes: Nicole was waffling about us going this year because of what the fuel was going to cost. I told her we could just about guarantee that gas isn't going to be cheaper in 2024.
 
I forgot to explain why I chose a shiny fairlead. I found this one on ebay for $25. I like that is 1.5" thick as opposed to 1". It works better for sharper angles which I figure will probably be a regular occurrence on the rear winch. I debated about painting it, but I don't think the paint would hold for long.

20230731_140519.jpg

I'm on the fence about the Sidewinder deal. I had originally picked it up for the front winch, but I don't like how far it sticks out. When I've got some spare money in the future, I may do something different.

Still gotta decide on a plan for the license plate.

You could run like I run my front, where it attaches above the fairlead to something. That way it doesn't stick out. But for the rear you also could just run a small hook.
 
License plates are overrated
With all the expired plates I see around, a lot of people would agree.

I'm thinking about just putting a pin thru the loop in the rope end and then hinge the plate over the fairlead.
 
I welded the hood pin brackets to the core support. You can see the little #10 toggle wing bolts I used to hold the hood down for the drive home. I did get them painted black after I was done.

A couple of years ago I noticed one of the Jeeps in the local club had a few neat looking trail badges on his Jeep. That's how I found out about the "Jeep Badge of Honor". I was looking at the list of trails earlier this year and realized I've done 9 of the 11 Utah trails and 5 of the 6 Colorado trails. Plus the Rubicon is also on the list. https://www.trailsoffroad.com/blog/the-complete-list-of-jeep-badge-of-honor-trails I decided to make my own sticker versions of the badges.
