2018 Volvo S60 Polestar Rear Wheel Bearings

Carquest Premium hub assemblies have been rigorously quality tested to ensure they meet Original Equipment (O.E.) specifications and provide the same reliability and durability expected from OE parts. All Carquest Premium hub assemblies are coated with an obsidian e-coating that protects the hub from rust and corrosion. Our stringent manufacturing processes and high-quality components allow us to stand behind our Carquest Premium hub assemblies with an industry-leading warranty.

Product Features:

• Engineered for OE fit, form and function
• Fully coated with an obsidian e-coating for enhanced rust and corrosion prevention
• High-quality steel and surface treatments for proper fit and endurance
• Roll-form bearing design applies exact preload for increased durability (where applicable)
• Bearings and seals are engineered to the requirements of each specific vehicle application
• Superior ABS sensors with matching signal and enhanced cord insulation for durability (where applicable)

SKF is a supplier of original equipment wheel bearings, hubs and seals to most of the world’s leading automakers. SKF wheel hub bearing units carry a flange for wheel and brake rotor attachment and a second flange for fixing the unit to the suspension. This fully integrated system provides a significant simplification in corner design and handling when compared with more traditional designs. The dynamic load carrying capacity is maximized by the use of a separate inner ring for the inboard ball row. This ring is mounted with an interference fit. The outer ring flange is bolted to the suspension. The rotating inner ring, with its tough flange, spigot and threaded holes or studs, is designed for mounting of the brake and wheel. Greased and sealed for life, the SKF wheel hub assembly is used for both driven and non-driven wheel applications. For driven wheel applications, torque is transmitted to the inner ring via an included spline.

Product Features:

• OE sensors assure correct ABS functions
• Premium seals, both inboard and outboard, protect the bearing
• Wheel bearing design with ball bearings or tapered roller bearings and integral wheel hub.
• The bearing units have preset internal clearance, are supplied greased for life and have integrated seals.
• Precision bearing pre-load and correct application of advanced manufacturing techniques such as orbital rolling
• 100% tested to the actual OE specifications per part number for fit, form and function
• High quality steel and surface finishes
• Proper implementation of heat treatment

Wheel Hub Assembly

WJB Automotive wheel hub assemblies are made with high precision through state-of-the-art technology and manufactured with strict quality-control criteria. Every wheel hub assembly is specifically designed to fit the designated applications and may be used as a direct replacement for the original part. Each part is engineered using OE data and measurements to ensure fitment, performance, and longevity.

Product Features:

• Fitment and function are ensured by precision machining, rigorous testing, and meticulous inspection of material and components.
• WJB Automotive wheel hub assemblies are designed to meet stringent fatigue requirements in order to reduce premature failure.
• Reinforced seal design material allows for optimal performance in harsh environments.
• WJB Automotive wheel hub assemblies undergo heat treatment and cold-forming processes that harden the surface ensuring high-temperature resistance and durability.
• Where applicable, pre-installed speed sensors will automatically sync to the vehicle’s anti-lock braking system upon successful installation and provide accurate speed-reading data.
• Brand may vary by location
