Dorman 686-340 Front Passenger Side Steering Knuckle OE FIX

The Dorman 686-340 OE FIX steering knuckle provides a superior replacement solution for front passenger side steering knuckle failures on select Lexus GX460 and Toyota 4Runner models. When wheel hub assemblies need replacement, rust and corrosion can cause the original hub and knuckle to seize together, making the knuckle difficult or impossible to salvage—especially in Salt Belt regions or vehicles with extended service life.

OE FIX Innovation:

• Features patented and proprietary anti-corrosion coating that prevents bonding between knuckle and hub bearing surfaces
• Provides more permanent and reliable repair compared to factory knuckle design
• Eliminates common failure point that requires hydraulic press removal or component replacement

Key Features:

• Direct replacement engineered to match original equipment performance and tolerances
• Constructed from high-quality steel with black finish
• Location-specific design for front right (passenger) side installation
• All stock mounting holes and threaded bolt holes precision-machined
• Bare knuckle design (hub assembly sold separately)
• Sold individually

Backed by Dorman's team of product experts and over a century of automotive aftermarket experience, this steering knuckle delivers a cost-effective repair solution that addresses the root cause of a common maintenance problem.
