Timken SP450101 Wheel Bearing and Hub Assembly - Front Left

Timken Wheel Bearing and Hub Assembly SP450101

Timken SP450101 is a front left wheel bearing and hub assembly built for driven applications that need stable wheel support, accurate wheel-speed signal performance, and consistent braking feel. It is compatible with 1997-2004 Dodge Dakota and 1998-2003 Dodge Durango front left positions.

Key Features

• OE-developed testing is used to control design, materials, and manufacturing process.
• Low runout helps reduce wheel-end noise and vibration.
• Premium seals use a reinforced outer case, ribbed inner diameter, contamination exclusion features, and vent holes to support sealing and installation durability.
• Precision-profile bearings with uniform internal geometry and enhanced surface finishes support load capacity and bearing life.
• ABS sensor is 100% tested for wheel-speed monitoring in anti-lock braking systems.
• 31-spline driven hub design with 6 wheel studs and a 4.500-inch bolt circle.

Detailed Description

Timken SP450101 is a driven wheel bearing and hub assembly engineered for front left service on Dodge Dakota and Dodge Durango models listed in the fitment data. The assembly uses a 3-bolt flange pattern, 6-stud wheel mounting, a 114.30 mm bolt circle, and hub, wheel, and brake pilot dimensions that support proper wheel-end alignment. Timken’s manufacturing approach focuses on controlled geometry and surface finish, which helps maintain smooth rotation and consistent performance in daily driving and braking conditions. This part cross-references SKF BR930204 for the same application.

What It Helps Address

• Wheel-end humming or growling from a worn hub bearing
• Excessive vibration felt through the steering wheel or chassis
• ABS warning concerns related to wheel-speed signal issues
• Uneven braking feel caused by hub runout or bearing wear
• Loose or unstable front wheel support on driven applications

Installation Notes and Tips

Verify front left fitment before installation on 1997-2004 Dodge Dakota and 1998-2003 Dodge Durango. Inspect the knuckle, axle interface, and mounting surfaces for wear, corrosion, or damage before installing the new hub assembly. Confirm the ABS connector routing and sensor alignment during service, and torque all fasteners to the vehicle manufacturer’s specifications.

Quality Assurance

Timken uses OE-developed testing and controlled manufacturing processes for hub bearing assemblies. The design emphasizes low runout, premium sealing, precision bearing geometry, and tested ABS sensor performance to support consistent wheel-end operation.
