Well, figured it was about time for an update!
I've got the rear axle finished up. 14 bolt semi floater with 5.13s, an ARB locker, Black Bird Customs rear disc brake conversion, 1350 yolk, all new seals and bearings. I've got some shock tabs and spring perches on the way to set the pinion angle and set it up for the NBS truck, finally I topped it off with a HD plate diff cover. I am going to run the stock 54" springs with a zero rate and an ORD shackle flip to net around 7 - 8" of lift.
For the front, I purchased a 79 Ford Hi-pinion D60 and just dropped it off to have an ARB locker and 5.13 gears installed. I've got an ORD crossover steering setup on the way for it, as well as all new kingpin components, bearings, seals and brakes. Should have it all pulled together within a couple more weeks. Like the rear, I'll be running a 1350 front yolk and an HD plate diff cover. For my suspension, I am going to be running the prototype ORD SFA swap brackets and some 52" springs for around 7" of lift. For both axles I have some ORD extended brake hoses on the way.
For the t-case, I've got a super short SYE on the way, and will be running a HAD driveline brake to go with the HAD long slip / high angle CV driveshafts.
For armour, I'm going to be running an ARB front bull bar with an M12000 Warn winch, and a custom built rear bumper with a swing out tire carrier. I've got a set of 5 17" Trail Ready bead locks in the shop, with a set of 37" Kevlar MTRs to go on them. To run the ARBs, I put my York OBA setup onto the truck a while back. Its been pretty useful up here, I've inflated a few flat tires with it already, haha! Might need to find some better tires for the truck...
Anyways, my Duramax suffered a vane position sensor failure recently, and I just dropped the truck off to have it fixed up at the dealership. The only other vehicles available to me include my Tahoe, my K5 and a piece of crap 97 F250. Well, the F250 was my first choice, but it broke down just before I planned to head on the 270 mile trip home. The K5 has a broken t-case output bearing retainer and shakes like crazy at the best of times at any speed above 45 mph. The Tahoe was not running right with a PMD problem.
All that said, the little Tahoe was the best candidate of the three, so I loaded up some tools, filled the tank and hit the road. The little truck did me proud! Went all 270 miles with only two PMD related episodes (the PMD fails high, aka the truck goes WOT at random). Both times it was on the open highway, and was really not any kind of a risk other than the majorly high EGTs that come with wayyyy too much fuel poured into the engine.
So, it made me really proud, and proved that it can get me there in a pinch. Anyways, today driving home from work, I noticed that the truck was pouring a ton of black smoke out and she overheated on a hill that I have to climb up to my place. The turbo has never really seemed to do much in the Tahoe, it has something to do with the actuator for the wastegate. So, I did what any reasonable man would and wired it shut with some bailing wire, haha!
Does much better now! Actually makes some decent boost (to the point of setting an overboost code...) but I am not entirely concerned about it. Too little boost is much more hazardous to my truck in the short term than the 10 PSI this turbo is capable of making. The 6.5L is good with around 13 PSI.
I'm gonna see if I can take the stock vacuum actuator apart and build a custom boost controller with it, but I'd need to find some gauges up here to do that. I don't want to underboost / overboost it too much on the 4 hour trip home.
I love working on vehicles, but not so much when they are my sole means of transportation 270 miles from any help, haha!
BTW -- I tore those quad beams out and put the composites back in. They arn't much better (even with high watt PIAA drivers and relays to maximize voltage + the quad beam mod), but definitely better than those candle dim quad beams, haha! I just bought some TYC housings to replace the stock composites. My understanding is that they are way brighter and have a much better light pattern.
