2016 Honda Pilot: Rear Driveline, Aftermarket Catalytic Converters, and Broken Bolts

Driveline Replacement and Initial Assessment

• 🛠️ The 2016 Honda Pilot requires a rear driveshaft replacement due to severe vibrations, along with other repairs like tires, control arm, and brakes.
• 💡 The Dorman Products rear driveshaft is noted for its good quality and features replaceable U-joints.
• ⚠️ The original driveshaft's U-joint is seized, making replacement necessary, and the process involves dealing with encapsulated bolts that can be problematic.

Addressing Broken Bolts and Carrier Bearing

• 🔩 A broken bolt on the carrier bearing mount turned a simple job into a longer ordeal, requiring creative solutions like welding a nut to extract it.
• 💡 Heat from welding a nut helped loosen the stubborn bolt, demonstrating a practical repair technique.
• 🔧 New bolts were ordered for the carrier bearing, and the driveshaft was reinstalled, ensuring proper torque specifications were met.

Catalytic Converter Installation and Performance

• ⚙️ Aftermarket Walker CARB-certified catalytic converters were installed to save the customer money, though their quality is questioned.
• ⚠️ The installation of the rear converter was challenging, requiring removal of the tie rod end and tire, while the front converter required accessing through the core support.
• 📈 Initial scan data suggests the converters may not be functioning optimally, with one bank showing poor oxygen storage capability.

Test Drive and Diagnostic Findings

• 🚗 The vehicle's severe vibration is gone after the driveshaft replacement, making it much more pleasant to drive.
• 📉 Despite the drive cycle completing for most monitors, the catalytic converters show signs of not performing to OEM standards, with rapid drop-offs in oxygen storage.
• ⚠️ The video expresses doubt about the longevity of the aftermarket converters compared to the original equipment, despite them passing the initial monitor test.
• 🔧 The customer will return for the remaining repairs, including tires, brakes, and control arm, as time ran out for this session.
