98 4x4 project

[Travistyson1]

Hey guys about a month ago i picked up a 98 4x4 expy and a 99 EB expy for a price of 1400, the EB was supposed to have a blown motor. Since then i have tuned up the 4x4 and inspected the EB, it was missing 3 coils once replaced it runs great. Now i am for sure keeping the 4X4 and unsure about the EB, now the 4x4 has a lot of rust underneath and i noticed the engine block itself has a buildup of rust. Where would you guys recommend picking up a crate engine, i would prefer to get the dohc from a navigator if i don't have to change harness and everything else.

Is the EB not 4x4? Are they both 5.4?

 

[Travistyson1]

Yes the EB is not 4x4 and both are 5.4

Ok so here is where I am now. Just found out from the dealer i bought the trucks from that he cant get the title for the black one because the Honda dealership that took it as a trade and sold it to him, too many miles for them to sale on their lot, took in the wrong expy title from the original owner. Apparently she had a green one and a black one and whoever did the paperwork didn't verify they had the correct title so the black one will be parted. I really hate to do ot to a prefectly good running truck but oh well. So i will be swapping some of the EB features to the 4x4. Build to start soon.

Replaced the transfer case motor today, seems to have fixed the 4wd problem, but the previous owner disconnected the front drive shaft so There could be other issues. However i will have to wait until next weekend to reinstall that and test. Took the 22s off the parts truck.

Are the lift kits for the f150 and expedition the same. I thou check it read the use the same frame, it seems like there are a lot more options for the f150 than the expedition?

Ok so i have been slowly moving through things that need to be repaired. I have fixed the cigarette lighters, attached the front driveshaft, repaired the exhaust leak. I'm moving now to a problem that I'm not sure what is causing it. My AC controls for the front ac only works on high. Any idea what would cause this? Is it the switch or should i be testing resisters?

AC only working on high is probably the blower motor resistor, since the high setting basically means no resistance provided, or the resistor is bypassed all together. this should be very easy to replace, this issue is common with hondas too. or else i would check the switch for the AC control.

as for some general advice about your vehicles, be wary of the 4r100 transmission, which come with all 5.4 expeditions. its a pile. it can be upgraded though and made bullet proof for not a lot of money. 2-3 upshift valve, and some final drive snapring are the main components which need to be upgraded, but there are several others

oh, and for the love of god, take off those damn rims ASAP

 

[Travistyson1]

Lol I will bet getting new rims and tires. Unfortunately the stock ones were bent badly do i took these off the parts truck. It was the resistor pick I replaced that with the one from my parts truck this morning. Thanks for the advice on that and the transmission heads up. We intend to basically rebuild this truck to be our family vehicle for a long time so i will definitely add transmission to the list. I'm at witts end with my turn signal hazard lights issue. Checked wiring nothing looks broken or pinched. The work when they want too. Figure i will change it the multifunction switch next week and see if that fixes things. New rotors calipers and breaks next week and replacing all my brake lines soon with the stainless steel ones i ordered. Lot of work but i don't like doing things twice

Ok I'm at a loss at my new hiccup. A few months ago i replaced the transfer case shift motor and I was able to hear it changing from 2wd to 4 awd to 2h to 2L. Now that i finally get the front driveshaft on after fighting that stupid thing now I only have 2wd and 4 awd lights on the dash no 4hi no 4 lo . It shows 4awd when I am in any 4WD setting? I have checked my vacuum lins all appear to be in good condition. I have not had a chance to do a voltage test on the actuators. To me its just very strange that I could hear it engaging at the xfer case after the shift motor install, and now a few months later nothing at all. In addition I discovered the lever on the front axle that should engage also is not moving.

Ok by the sound of it I think my 4wd issue is resolved. I have a lessor issue where my indicator on the dash is slightly off on the gear it is actually in. There is a small white clip broken under the dash connected to the indicator. Reached my hand under and adjusted it while in Neutral and guess what. The clunks indicating the gear change is back.. That indicator being off was causing the issue

Ok knocking things out left and right but everytime I do I find something else. The joys of not buying new. So No I am looking for a wiring diagram for the tail lights, rear blinkers etc. So ac motor was the resistors thats fixed. 4wd was the shift cable being slightly off so I would not allow the truck to engage. Now I fixed my blinker not working issue, for now. it seems that either the Idiot that hooked up the radio tapped into that fuse for the blinkers and its very loose or ran a wire that is consequently also powering the radio as some sort of bypass. But upon getting my flashers and turn signals working I discover the pass side turn still doesnt work, not the bulb and the drivers side brake and running light not working. They have a red wire jumpered from the drivers side blinker? It wasnt working so I ripped that ghetto rig out and fixed the harness but still not getting the drivers rear brake/running light nor the pass rear blinkers. Anyone have a wiring diagram so I can trace back to find the issue, or run new wires to resolve?

If you read most electrical problem posts on this forum, nine out of ten times, it's usually some yahoo tapped into something for power. These vehicles are very sensative as to any thing piggybacked to acquire a quick 12 volts. It's more work, but aftermarket stereo, or any accessory is always better to hook the hot lead directly to the battery. The switchable 12volt signal can be tapped off something existing, be even that's chancy, as you have discovered. Sounds like you've picked up a challenge of a vehicle. Now you know why the last guy sold it!
