Could well be a broken wire. Test procedure: Disconnect the wire from the oil pressure sender. Turn on the ignition (you can start the engine, but you don't have to. But the ignition has to be in the RUN position, not the Accessory position. With the wire disconnected and not touching anything, the needle should be pegged at the high and of the scale. Touch the wire to a good ground (like a clean spot on the engine block. The needle should swing to zero. If the needle doesn't read zero when the wire is grounded, you have an open connection between the sender and the gauge.

What year truck?

This. If you need the flex on trails, use quick disconnects for the links. On the street you NEED a sway bar unless you enjoy driving your truck on its roof.

Another possibility is that the computer thinks the old HDD is a DVD with a disk in the drawer, and it's set to boot from the CD/DVD if a disk is present. Checking the boot configuration in Setup should tell you that.

Welding would probably be better, but covering up an enlarged tranny opening isn't a structural repair. I was going to use either mastic or construction adhesive, and screw the repair panel over the transmission tunnel. The separate piece that encloses the factory opening for whatever transmission you have is attached with screws anyway.

My '88 4.0L MJ had the floor butchered by a previous owner. I went to a junkyard and had them cut out the section of an XJ tranny tunnel that surrounds the shifter, along with the screw-in cover plate. I haven't put it all together yet, but I think just cutting the section out of a junked XJ is the way to go.

You may be using the correct terminology but, if so, the symptoms are confusing. Usually, the dashboard turn indicators lighting up is caused by a fault in the parking light sockets or ground, causing the parking lights to seek a ground by back-feeding through the turn signal circuit. That back-feed current is what's lighting the dash indicators. But the headlights don't share a socket with the turn signals, although they do share a ground, so the issue could still be a bad ground. What happens if you turn on the parking lights -- not the headlights, ONLY the parking lights? Second test -- remove the headlight bulbs from the sockets and then turn on the headlights. Do the dash indicators light up? On the rear lights, is it the taillights that are lit constantly, or is it the brake lights?

Quick test -- if the blower runs when the control is set to the highest speed -- the problem is the resistor pack, not the blower.

Obviously, if the damage is limited to the spider gears, another set of spider gears is going to be the least expensive route. Beyond that, the Dana 35 probably isn't worth rebuilding when you could likely buy a late-model Cherokee Chrysler 8.25" axle and have it installed for less than the cost of rebuilding the dana 35.

Do the turn indicators only come on with the HEADlights, or do they come on with the parking lights?

Tail lamp wire in the radio harness?

"I'm from the government Air Force. I'm here to help [obfuscate, obstruct, and delay]."

Looks more like a combination of wildlife refuges, state, and national parks/forests. Where are all these military bases of which you speak?

Direct bolt-in. No changes. Let me amplify what Pete wrote. It isn't that " the individual parts aren't necessarily compatible year to year." The parts ARE NOT compatible from year to year. You MUST buy hubs, bearings, rotors, and calipers for a '98 Cherokee. Nothing for an '88 MJ will fit or work. If you ever have to replace a steering knuckle, that has to be for a '98 XJ, as well.

I just looked up Tyndall AFB on Google Maps. Good grief! Who the [bleep]in' [bleep] ever thought it was a good idea to construct a permanent Air Force base on a barrier island? Tyndall was originally a gunnery range during WW2, and it made sense (from the non-environmentally oriented perspective of WW2) to use a barrier island as a gunnery range -- all you're bombing and strafing is swamp and pine trees. But to build it up into a long-term, major air base? Idiocy. Now that Mother Nature has started the work, the gummint should just raze the whole base down to the ground, restore the site to some semblance of natural barrier island ecology, and relocate Tyndall (or its functions) either to a new base to be built inland, or to a nearby (relatively) base that's farther inland. To rebuild the base would be monumantally stupid.

Bo, it looks like you're going to need a couple of chainsaw chains. And you'll be able to heat your house with wood for about ten years.

Don, it looks like you daughter is going to be with you for awhile. https://weather.com/safety/hurricane/news/2018-10-12-tyndall-air-force-base-damage-hurricane-michael

Where is it leaking? If it's leaking around the cap, get the Volvo cap cruiser54 recommended.

Ouch! Good news that she, her husband, and the dogs are safe. Not good about the house, but hardly surprising. What really [bleep]s me off is the looters. WTF is wrong with people that they steal from other people whose whole lives have been destroyed? I think looters should be shot on sight. To use an expression we knew too well in the Army back in the Vietnam era, looters are lower than whale [poop] at the bottom of the ocean. The next thing your daughter and son-in-law will have to watch out for is the scam contractors. Any time there's a disaster like this, there just aren't enough contractors available locally to deal with the magnitude of the work to be done, so outsiders come in. Some are good, some are okay ... and many are fly-by-nights who are just there to make a quick buck. It can be difficult to know one type from another.

Obviously you've never lived in coastal Maine.

The closed system doesn't have an overflow. What are you calling the "overflow"? How full do you fill the tank on the firewall? It should be filled no more than halfway, when cold. It needs air space for the coolant to expand as it heats up.

What year MJ? Open or closed cooling system? Has the radiator ever been replaced? Lacking the above information, my guess is that you need a radiator. My '88 XJ, at 287,000 miles, is on its third.

The early base (SporTruck) models didn't have the dual mirrors mounted at the vent window corners, and the trucks with tow mirros (such as Tim's truck in the photo Hornbrod posted) also didn't have them. This was also true for XJs with the tow mirror option. So check junkyards. This might be a good project for someone with a 3-D printer. It's a small, fairly simple part. Who here has a 3-D printer and scanner setup, or access to them?

Heh, heh ... I was going to ask you that.
