    Flat towing, engine off, p/s fluid question

    I permanently mounted a tow bar on my old '88 K1500. It's not licensed and I've got some stuff to fix, namely the leaking power steerimg. What happens to power steering fluid when the engine isn't running and I'm flat towing it? Does it just stay in the p/s pump and bypass internally? I never...

    10 bolt brakes

    Leading/trailing vs duo servo, obviously the latter is preferable. The duo servo is stock on my Yukon. The leading/trailing is on my RC stepside. Here's the question. Can the entire Yukon duo servo backing plate, shoes, drums get swapped to the stepside truck? Because the Yukon is getting a...

    Dual Alternators

    Non A/C truck, factory "bypass" pully, and she runs great. But with: headlights, heater fan, amber warning lights, tunes, wipers, snow plow, and low RPM... clearing out 14" of fluffy white goodness from 3 driveways seems to draw down the (new last September) dual batteries. So I'm pondering a...

    Exhaust drone elimination

    1995 Chevy 2500 chassis cab that had a service body when I bought it. Yanked it and put on a flatbed, tool box, dual spare tires, the whole Baja look. The original muffler is long gone, due to New Yuck salty winters, and its replacement was in the same condition when I bought the truck. I wanted...

    Exhaust diameter

    Question first then explanation. What effect does a short section of small diameter exhaust pipe after the "muffler" actually affect? Higher exhaust note? Now, I say "muffler" because theres no back pressure in the tailpipes and I'm deleting the muffler anyway. The Vortec 5.7 and its dual...
