2010 Chevy Impala: Replacing Rear Wheel Bearing & ABS Harness

Diagnosing the Issue

• 💡 The 2010 Chevrolet Impala presented with ABS and traction control lights due to a faulty left rear wheel bearing and a damaged ABS harness.
• ⚠️ Corrosion was observed on the bearing's pins and the harness, indicating a need for replacement.

Wheel Removal and Brake Inspection

• 🛠️ Swollen OEM-style chrome cap lug nuts required a specialized 19.5mm socket from an Astro Tools set for removal.
• ⚠️ The video notes that the vehicle's brakes are in poor condition, but the repair is limited to the bearing and harness as per the customer's request.

Rear Bearing and Harness Replacement

• ⚙️ The caliper was removed by unbolting the 13mm bolts, revealing that the brake pads were still at about half life.
• 🧩 The parking brake mechanism was partially disassembled to access the bearing and harness, involving the removal of a slack adjuster and cable.
• 💨 An air hammer was attempted for hub removal but ultimately a slide hammer proved more effective due to rust.
• 🔩 The backing plate was removed by taking out screws with Loctite, and the old bearing was extracted.
• 🔌 The new bearing and harness were installed, ensuring the connector was oriented correctly.
• 🔧 The parking brake shoes and cable were reassembled, with attention paid to the correct orientation of the rubber boot and spring.

Harness Installation Challenges

• ⚠️ The existing ABS harness had multiple previous repairs and metal retainers that made removal difficult.
• 🧩 New zip ties and metal retainers were used to secure the new harness, ensuring it did not rub against the control arm.
• 💡 The process involved carefully routing the harness through brackets and ensuring the connector could be properly seated.

Additional Repairs and Observations

• 🚗 The video briefly touches on a Dodge Journey with emission monitor issues, likely related to a thermostat fault (P0128).
• 📦 The cluster from the Impala also needed to be removed and sent out for repair, with Circuit Board Medics chosen over United Radio for a flat-rate repair.
• ✅ The rear bearing and ABS harness replacement were completed successfully, with the parking brake cable reconnected and adjusted.
