Reviving a 1990 Ford Foxbody Mustang: From Abandoned to Awesome!

Foxbody Revival Project

• 🚗 The 1990 Ford Foxbody Mustang, owned by the host, had been sitting abandoned for several years due to various mechanical issues.
• 💡 The decision to revive the car was inspired by a recent project, leading to the goal of getting the Foxbody running and driving again.

Initial Assessment and Mechanical Fixes

• 🔋 A dead battery was replaced, and surprisingly, the 5-year-old gas and fuel pump still worked, allowing the car to start.
• ⚙️ Noted issues included a bad clock spring in the airbag, a worn output bushing on the transmission causing driveshaft vibration, and a poor idle.
• 🛠️ The transmission's output bushing was identified as severely worn, requiring replacement along with a new driveshaft yolk and seal.
• 🔧 The steering rack and pinion was adjusted, significantly improving its tightness and eliminating leaks.
• 💨 The smog pump was removed, and the exhaust ports on the heads were plugged with custom-welded bolts.

Rear End Overhaul and Upgrades

• 🚀 The rear end was disassembled to install new 3.73 gears, aiming to improve performance and drivability.
• 🔍 The process involved careful marking of bearing caps, removal of the carrier and pinion, and meticulous reassembly with new bearings and shims.
• 📊 Gear pattern testing was performed using paint to ensure proper contact between the ring and pinion gears, requiring adjustments to pinion depth and carrier shimming.
• ✅ The rear end was successfully reassembled with proper backlash and preload, ready for the axles and cover.

Cosmetic and Interior Restoration

• ✨ The car's exterior received a thorough polishing, revealing a surprisingly vibrant red paint color previously hidden by years of oxidation.
• 🧼 The interior was cleaned extensively, addressing mouse and spider activity, and the driver's seat bracket was repaired by swapping rails from another seat.
• 💡 New OEM-style headlights and marker lights were installed, significantly improving the car's front-end appearance and visibility.

Final Touches and Test Drive

• 💨 The AC system was serviced and found to be working, providing cold air.
• 🔧 An engine idle relearn procedure was performed, resolving a rough idle and setting the engine to a stable 900 RPM.
• 🛣️ A test drive confirmed the improvements, with the 3.73 gears making the car much more drivable, the vibration gone, and the steering improved.
• 🎉 The revived Foxbody, now shiny and functional, is ready for its next adventure, highlighting the car's affordability and performance potential.
