I registered today on the forum mainly to hear some replies on what went wrong.
I purchased the Tahoe in Feb 2020 and it looked like a granny grocery getter and was fairly clean. I immediately put a Rough Country 4" lift on it, removed the running boards, and put some MT wheels and Toyo tires. Since then, I have put a new duel exhaust with turn outs behind the rear tires, flowmaster 40's, welded on rock sliders, and just this week, a new rubber floor mat to replace the worn out, stained and nasty carpet. Along the way, I have grown to not like the push button 4x4 activation. I set out to replace with a 241C that I had lying around the shop. I dropped the front diff and resealed and replaced drive bearings. I had a friend swap the t cases and install new u joints in both driveshafts. I finished the mechanical install, and have been working on the wiring changes so that the floor 4x4 lights would work, and the front diff actuator would work. I had the shift linkage working and the speedometer working. I HAD NOT hooked up the front diff actuator.
This week when I picked up the Tahoe from the upholstery shop, the guy said "hey you might want to make sure it is not in 4WD, I had to move the shifter a few times." I thought I had it in 2WD, and took off. 6 miles in, I heard a thump and then a slam and a few seconds later the engine quit.
Apparently, front driveshaft engaged or something to cause front driveline to resist turning from Tcase. The front tcase output shaft ear sheared off, and the driveline wobbled around under the driver seat grabbing whatver it could. End result: 2 miles of wiring wrapped around DS, hole busted in side of Tcase, shifter for tcase left in the road, trans shifter cable end left in road, bottom side of cab beat to crap, wiring going up front grabbed and broke off distributor cap and bent some of the brackets that keep the wiring organized and secured. Needless to say, I have a mess.
All interior wiring appears to be in tack. Starter wiring appears to be in tack, headlight wiring appears to be in tack. All transmission wiring appears to be completely gone. All tcase wiring is gone. I am not sure about fuel pump wiring.
Today, I unhooked about 90% of the engine bay wiring harnes, removed driveline, and removed all skidplates, etc. Next, I am planning on removing the rear driveline, t-case, and wiring harness, and further investigate the damage. I am also looking for an engineless 99 donor vehicle that will have transmission and engine bay wiring. I have a 99 4 door parts Tahoe that is a 2WD, which is complete. Can I use any wiring off of it?
Do you have any suggestions?
