Detailed Description

SKF BR930548K is engineered as a front wheel bearing and hub assembly for a wide range of GM vehicles, including Chevrolet Impala, Buick Lucerne, Cadillac DTS, Pontiac Grand Prix, and Buick LaCrosse applications. The X-Tracker hub architecture is designed to increase load capacity while delivering a stiffer hub structure, which helps maintain consistent wheel support under braking and cornering loads. This part number, BR930548K, is a direct-fit option for many front-wheel applications and is also cross-referenced to 10305030 for the same application.

SKF has more than 100 years of engineering and manufacturing experience, and this hub assembly reflects that focus on dimensional accuracy and long-term service life. For fitment-specific searches, BR930548K is commonly selected for front wheel bearing and hub assembly replacement on Chevrolet Impala, Buick Lucerne, and Pontiac Grand Prix models with X-Tracker requirements.

What It Helps Address

• Wheel bearing noise from a worn front hub assembly
• Excessive wheel play or looseness at the hub
• Brake pulsation or inconsistent rotor support caused by hub wear
• Handling instability related to reduced hub stiffness
• ABS-related fitment concerns on supported applications

Installation Notes and Tips

Verify the vehicle year, make, model, and position before installation. This part is listed for front applications and also appears in rear applications on select 2005 Buick Terraza, Chevrolet Uplander, Pontiac Aztek, Saturn Relay, and Buick Rendezvous configurations. Confirm the flange dimensions and pilot measurements against the original hub before assembly, and inspect related suspension and brake components for wear during replacement.
