Dorman 686-361 Wheel Bearing and Hub Assembly - Front Left

Loaded Knuckle for Scion xD Front Left

Dorman 686-361 is a loaded knuckle assembly for the front left position on select Scion xD models. It combines the hub, bearing, and dust shield into one preassembled unit to simplify a repair that often requires pressing components separately.

For shops and DIY repairs, this OE FIX design reduces setup time and helps avoid the extra steps tied to a traditional wheel bearing service. It is a direct-fit replacement for 2008-2014 Scion xD front left applications.

Key Features

• Loaded knuckle assembly with hub, bearing, and dust shield already assembled
• OE FIX replacement for faster service than a press-in bearing repair
• Steel construction with painted black finish
• Includes mounting hardware and axle nut
• 26-spline hub configuration
• Standard grade replacement part
• Fits 2008-2014 Scion xD, front left

Detailed Description

This Dorman wheel bearing and hub assembly, part number 686-361, is built for the front left side of the Scion xD from 2008 through 2014. By supplying the critical components in one loaded knuckle, it eliminates the need to press a bearing into the knuckle during installation. That makes the repair more straightforward while keeping the original service location and fitment requirements in mind. This part cross-references Toyota OE numbers 4321252050 and 4350252040 for the same application.

What It Helps Fix

• Wheel bearing noise from a worn front hub assembly
• Excessive play or looseness at the front left wheel
• Vibration or roughness related to bearing wear
• Service delays caused by press-fit bearing replacement
• Damage or corrosion around the original knuckle and dust shield area

Installation Notes and Tips

Verify front left fitment before installation on 2008-2014 Scion xD models. Inspect the axle nut, hub splines, and surrounding suspension components during service, and confirm all mating surfaces are clean before assembly. Because this is a loaded knuckle, installation is simpler than a press-in bearing job, but proper torque procedures should still be followed.

Quality Assurance

Dorman OE FIX parts are engineered to replace difficult original repairs with a more serviceable assembly. Part number 686-361 is built as a standard replacement for the specified Scion xD front left application.
