Been too cold for me to want to get in the garage lately, but it hit 51 today so I stopped hibernating and went out to work.
Received the hold-down bracket from TGW, nicely rubberized coating, and fits over the battery perfectly:
https://teamgrandwagoneer.com/batter...-gw-1986-1991/

Also received the J-Bolt kit I ordered from Remy.com:
https://remybattery.com/battery-hold...lt-6-inch.html

Pay no attention to the junk yard J-bolts, they were too long and didn't work -- the 6" Remy.com j-bolt kit was perfect:

Got everything put on, excellent fit:

Back to work on the beast. Since I'll be moving to AZ in a couple weeks I thought I should inspect the taillight assemblies and fix any problems.

I discovered the taillight lens gaskets were missing in a couple places so had to clean some crud out, and surface-rusted bulb sockets that needed addressed. This is prior to cleaning the sockets:
PXL_20220501_210417650 by Robert Stone, on Flickr

Got it all cleaned up, used some bulb grease, and put everything back together after using some gasket maker to rebuild the missing gasket sections:
PXL_20220423_204403180 by Robert Stone, on Flickr

Right side lens is the one I used polishing compound on here, and it does look better than the left one, but I'll hit both with the orbital buffer once I remount them:
PXL_20220423_201810367 by Robert Stone, on Flickr

Also addressed the rear differential today. Owner's manual said 80W-140 gear oil is best for the factory tow package so drained the old fluid, which didn't look bad at all, cleaned the crud out, rotated the wheels to ensure the gears look good, regooped the cover, put everything back together, and refilled. Front diff will be done tomorrow:

Tackled the front differential yesterday. Cover is date coded to 1977, thought that was a bit odd. Otherwise, nothing exciting:

Doing some detail work on the beast to get her ready for the long haul to AZ.
Lug wrench sanded, primered, and painted:
PXL_20220504_152504520 by Robert Stone, on Flickr

Also installed the new TBI injection warning light in the spare housing slot area to the left of the steering column. It's a bright yellow LED I can see from miles away. Wiring is apparently directional, good thing I checked before I wired it up.
PXL_20220504_152311358 by Robert Stone, on Flickr

Also screwed the OBD1 diagnostic port up under the AC ventwork, took the access cover off, measured, and drilled holes to put it above the tranny turnnel:
PXL_20220503_224553549 by Robert Stone, on Flickr

Also got the factory towing package wiring repaired. The original Jeep bracket that held the 7-wire connector under the rear bumper had been damaged, which likely also damaged the connector, so someone had badly wired in a 4-pin connector instead. I got all the wiring traced out, reconnected, reorganized, and retested under the spare tire area for the trip. Also swapped out the 224 relay under the dash for a 552 so the system blinks faster:

3rd shot also showing the factory module that still works great:

Still getting a few things ready for the AZ move. Took the beast for a 40-mile roundtrip shakedown and discovered the old tires I put on the beast just to move it around were so bad on the highway that I decided on new tires immediately.
Behold the greatness of the 30x9.5R15 BF Goodrich T/A KO2. These are tried and true on zillions of rigs and I got a great deal, so had them mounted and balanced yesterday. Stock ride height for the foreseeable future, and didn't want anything potentially rubbing, so stayed with the narrower 9.5" width.

Also painted the wiper arms and installed new DL16 wiper blades, then filled the fluid bottle and tested everything out. Wish someone had done that prior to scraping up the driver's side of the windshield...:

Picking up the Uhaul trailer on the 10th, loading it, then heading to AZ on the 11th, with an overnight stop in Lost Wages, NV for arrival in Sierra Vista on the 12th.

Yeah, Marc, it sucks but the opportunity down there is just too good to pass up.
My wife is staying in Boise a couple months so I'll be back up here to move or sell some other stuff later, so maybe by then you'll be up here and we can meet up.

Figured I'd update this thread now that I have some time. All went according to plan and I averaged about 8.5mpg on multiple fill-ups, which isn't bad for an old '88 hauling a 12ft dual-axle trailer full of tool-box, tools, parts, work bench, and many boxes of household goods.
Not sure on weight, but the beast really struggled in a snow storm at ~7,000 feet elevation (no timing adjustments on my Howell TBI install), and on some of the steeper grades past the Hoover Dam headed into AZ.
I had it floored on many sections where it kicked down to 2nd gear and stayed at 45-50mph. She's due for a coolant and oil/filter change for sure.
Been setting up everything in the house so won't be updating the thread for a while, but will update on what I find when I get that maintenance done.

Glad you made the first trip, without incident other than barely passing the next gas station

I know I'm going to enjoy hauling the rest of our stuff from Boise to Sierra Vista a LOT more behind our Escape Hybrid!

Oh man, yes. Those old mudders would've driven me nuts with their howling and uneven tread blocks shaking everything. I was amazed how smooth the KO2s drove, waggy felt great, save for the loose steering from slightly clunking ball joints and VERY worn steering box.

I had some time recently to troubleshoot and diagnose a rough running issue the beast developed on the drive from Boise to the bottom of AZ.
I created a new thread here to discuss rebuild and performance options:
https://ifsja.org/forums/vb/showthre...75#post1735975

The following is just copied and pasted from that new thread to document here.
I popped off the air cleaner assembly to begin diagnosis and was met with a ton of oil soaked into the air filter and drowned insects:
PXL_20220615_001841059 by Robert Stone, on Flickr

The oil in the air cleaner told me I had a major cylinder compression leak into the crankcase forcing oil up into the breather tube, so I decided to take out all the plugs to localize the problem.
I discovered both the #5 (3rd back on driver side) and #8 (furthest back on passenger side) plugs just bashed and mangled. Great, the Jeep had turned into a V-6!
#5 electrodes almost touching:
PXL_20220615_004615686 by Robert Stone, on Flickr

#8 electrodes touching and porcelain missing:
PXL_20220615_011313746 by Robert Stone, on Flickr

Knowing bashed plugs come from debris in the cylinder, I decided to scope them both. Behold, I have missing bits from the piston crown and cratering in other areas. Pic shows the cylinder in top right with crown damage, and mirror image seen on cylinder wall in bottom left:
PXL_20220615_020847107 by Robert Stone, on Flickr

I'm thinking it ran hot/lean/bad at some point, caused the breakage to those 2 piston crowns, and the bits bashed the plugs. I know it started running rougher and hotter than normal near Las Vegas, but I blamed that on the weather and altitude at the time. I now know those 2 dead cylinders were causing the rough and hot running.
The only cause of the damage I can point to is when the engine stopped running on the highway 3 different times during the cold weather part of the trip in NV @ 7,000ft. Oddly, it never cut out in sweltering Las Vegas or throughout the hot AZ portion of the trip, so I wasn't sure if it was the Howell kit, or something else that caused the engine to just die completely in the cold weather. Oddly, I never heard any pre-detonation or any other warnings before it cut out those 3 times. Engine just quit suddenly, so I pulled over and restarted the engine without any issues.
Since I was towing about 3,000 lbs of crap in a uhaul trailer, I just kept going till I got to SV, and parked the beast in the garage.

I'm currently trying to figure out the best path to get her back on the road. Thought about an LS swap, but I'd rather just keep the stock engine, wiring, and controls in it to keep things simple, though I might throw an AW4 OD transmission in it at some point once I get the engine plans finalized.

Well that is a fine "Welcome to AZ" your truck gave you :/

Looks like a tear down, crack it open, and see what happened.

Do you suspect it started from above with debris through the intake?

Can't imagine head issues, as the problem is on opposing sides, but towards the rear.

I was pretty happy it made it to AZ, especially knowing I'd kludged a lifter replacement to get her running (old lifter was dished on #1 intake side so I just popped in a different lifter).
It was definitely the pistons coming apart in those 2 cylinders, as it had run fine for 100s of miles prior to that. I didn't even bother to scope the other 6 cylinders, figure the damage I saw in 5 and 8 was enough to tell me they're probably all pretty bad. Gotta figure it lean-burned into self-destruction when the engine shut down on the highway those 3 times in the snow. Still no idea what happened, as it started right back up and ran okay.

I have no idea how badly this old thing was cared for before I got it a couple years ago either, so I knew it was only a matter of time before I'd need to throw cash at the drivetrain. Good timing too, the rear main seal started leaking pretty bad on the trip.

If I can be convinced that Edelbrock heads will make a difference, then I'll throw them on a rebuilt short-block, along with a 4bbl intake, headers, and a modern day EFI system. Hoping I get some feedback in that other thread I created last night.

That does not look like damage; that looks like the notch that indictates the front of the piston...
