Update to come, but I backed it out this morning. Logged 52 miles before lunch. It’s awesome.

Prepping for a weekend with Upstate.

  • replaced the House battery dated from ‘22 and added an smart battery isolator. Instead of relying just on the solar DC to DC charger the isolator will help me keep it charged. Replaced it with another 27DC from Costco. For $89 it will do the job needed. With periods of storage in the garage, I’m sure I’m at fault for killing it without solar to keep it topped off.
  • Tracked down a coolant leak at the fire wall. It was the short elbow from the heater control valve back into the heater core. It was the one hose I didn’t replace last year during the swap.
  • Replaced the bushing at the wiper motor. Used a wiper bushing for a 1997 f150. I tried the replacement and 3D printed parts but could never get them to fit tight. Using a tie rod end puller it pressed right in.

Two weekends ago, Ezra, Sami, and I took the Jack on the annual Sandhills ride with the Upstate crew, and we logged about 900 miles in total over the weekend. This was the first big trip with the new rear long-arm suspension setup. Aside from local driving, this was the first real test of the triangulated four-link rear with air bags. I absolutely loved how it felt. The handling was noticeably tighter, and the truck’s responsiveness was predictable. I’m no longer worried about how it might react on the highway—everything just feels solid. Honestly, I’m so pleased with how it turned out that it’s got me thinking about tackling the front next.

The Land Cruiser hit a milestone, crossing 5,000 miles since the 5.3 engine swap last year, and it ran like a champ. The only hiccup was a bit of transfer case whine, and when we arrived, I discovered two lower shock bolts had gone AWOL. Luckily, that was an easy fix—thanks to a quick Lowe’s run. I swear, every time I meet up with Charles and Lee, a shock mishap happens! But all in all, a couple of bolts were all that went wrong, and we were back on the road in no time!

Another hiccup on the trip was that the sensor for my automatic electric fans stopped working. I noticed it while idling in a drive-thru—the temps crept up, but the fans didn’t kick on. Luckily, with the cold weather, as long as I kept moving, temps stayed in check. Shoutout to Mosley Motors—they went above and beyond. I reached out over a year after buying the LS swap radiator and fans from them, asking about a replacement sensor. Without hesitation, they sent one out right away and just asked me to return the old one for inspection. That’s top-notch support!

I wish we could have stayed longer, but we had to cut the trip short and head back early due to some freezing rain rolling in. Even so, it was one for the books, miles of adventure, and a reminder that both the Land Cruiser and the community around it are what it’s all about.

Thanks to @aquatech3 for remembering to take pictures. Im horrible at remembering when I’m having a good time.

Stopped for a quick history lesson.

For the last 1000 miles, I’ve been dealing with a whine in my transfer case that starts around 45 mph. The case has also been seeping a bit, so I needed to open it up to replace the gasket anyway. While checking things over, I confirmed that it has the 38 mm idler. I went ahead and ordered a rebuild kit so I’d have everything on hand before opening it up to track down and fix the whine.

One of the first 38mm cases since the change from 34mm.
Case # 6D0704
Case 704 built in April 1986

New heater control valve came in from across the pond. 87240-90A00

I may have stumbled onto a pretty slick solution for LS swaps. I haven’t seen this done before, so this might be a first.

I was able to disassemble the heater fitting and reassemble it rotated 90 degrees. That simple change eliminated two hose clamps and created a much cleaner layout for the 5.3 heater hoses.

Sometimes it’s the small tweaks that make the biggest difference.

Neat, but there's no need to do that if you use the right hose combo :)
