Rare Quadrasteer GMC Sierra Found at Auction for $5700 - Full Restoration & Fixes

Auction Discovery and Initial Purchase

• 💡 A 2005 GMC Sierra with the rare Quadrasteer option was found at auction, with the seller unaware of its special features.
• 💰 The truck was won for an astonishing $5,700, significantly below market value for a clean GMT800 truck, due to the seller not knowing its true rarity.
• 🚀 The Quadrasteer system, which offers rear-wheel steering, was a unique feature that GM only offered for three years.

Restoration and Mechanical Repairs

• ✨ The truck was shipped from Atlanta and found to be in remarkably clean, rust-free condition, with mint cab corners and factory billet wheels.
• 🛠️ Initial diagnosis revealed a misfire and check engine light, traced to a missing bolt on the exhaust manifold, which was easily fixed with a bracket.
• ⚙️ Extensive work was performed, including replacing spark plugs, wires, an exhaust manifold bolt, a water pump, an AC compressor, a transfer case, and addressing a cracked oil cooler gasket.
• 🔧 The Quadrasteer system's rear differential fluid was found to be chunky and metallic, indicating a need for replacement, which was done with Amsoil Severe Gear fluid.
• 🚗 Steering and suspension components were also addressed, including replacing tie rods, pitman arm, idler arm, and sway bar end links, along with installing a steering shock for improved handling.

Quadrasteer System and Driving Experience

• 🎯 The Quadrasteer system, a $5,600 option in 2005, allows for incredible maneuverability, making the large truck feel like a "drift mobile" with a tight turning radius.
• 🔊 The truck was brought back to life with no ticking or misfires, running smoothly after all repairs, including a fix for a dead fuel injector using just a punch and hammer.
• 🛣️ After a full fluid service (engine oil, transmission fluid, front and rear differential fluid), the truck was taken for a test drive, performing well with smooth shifts and excellent handling.
• ⚠️ A temporary "service four-wheel steer" warning light appeared but resolved itself after a restart, and the truck exhibited "crab walking" before the issue corrected.

Value and Future Plans
