Detailed Description

The SKF CIR70 wheel bearing retaining ring is used with generation one wheel bearings to hold the bearing securely in the steering knuckle. Its measured dimensions of 3.066-inch inside diameter, 3.622-inch outside diameter, and 0.278-inch width help support proper seating during wheel bearing and hub service. This part is commonly used on front applications for Hyundai Sonata, Kia Optima, Kia Sportage, Hyundai Tucson, and related models listed in the fitment data. This part cross-references OE number 5171826500 for the same application.

SKF has supplied drivetrain and bearing components for more than 100 years, and the CIR70 follows the same dimensional and specification focus used across the brand’s service parts. For Hyundai Sonata front wheel bearing retaining ring replacement or Kia Optima front bearing retainer service, matching the correct clip is important for a stable installation and reliable bearing retention.

What It Helps Fix

• Rusted or damaged retaining rings removed during wheel bearing service
• Loose bearing retention inside the steering knuckle
• Improper seating after front hub or bearing replacement
• Noise or fit issues caused by a worn wheel bearing clip
• Repeat service from reusing a distorted retaining ring

Installation Notes and Tips

Inspect the steering knuckle groove before installation and clean away corrosion, debris, or old residue. Replace a used clip whenever it shows rust, bending, or damage from removal. Confirm the bearing generation and match the retaining ring dimensions before assembly.
