Dorman 686-406 Front Passenger Side Steering Knuckle with Anti-Corrosion Coating

The Dorman 686-406 OE FIX steering knuckle is engineered to solve a common corrosion problem that plagues original equipment knuckles on Ford F-150 trucks. When wheel hub bearings need replacement, rust often forms between the knuckle and hub surfaces, making salvage difficult or impossible—especially in Salt Belt regions.

Key Features:

• Patented anti-corrosion coating helps prevent rust formation between mating surfaces
• OE FIX design provides a more permanent and reliable repair than factory knuckles
• Direct replacement engineered to match original equipment performance specifications
• Position-specific design for front passenger side (right) installation
• Manufactured to strict quality standards using durable materials
• Precision-engineered to match original component dimensions for reliable fitment

This steering knuckle connects the wheel hub assembly to the vehicle's suspension and steering components, playing a critical role in proper wheel alignment and handling. Dorman's improved design addresses the root cause of bearing replacement difficulties, making future service work faster and more predictable for both professional technicians and DIY mechanics.
