TRW Automotive JBJ959 Front Upper Suspension Ball Joint

The TRW JBJ959 is a suspension ball joint replacement part manufactured to original equipment quality standards. This front driver side upper ball joint features sealed-for-life construction that protects from harmful elements, is maintenance-free, and uses the highest quality grease during manufacturing for optimal performance.

Key Features:

• Four levels of testing, technical, and audit review before approval, including endurance testing of 500,000 cycles
• Manufactured using forged or cold-formed steel with low friction polymer bearings that enhance damping and reliability
• Long-lasting dust covers made from the highest quality rubber to stop dust and water from entering the ball joint
• Low friction design restores steering and suspension systems back to their original operating performance
• Non-greasable sealed design with dust boot included

The outer housing is constructed from forged or cold-formed steel for maximum strength and reliability under harsh conditions. The highly polished ball stud is encapsulated within a high-strength polymer bearing for smooth articulation and free range of motion. This advanced design facilitates low friction, reduced heat generation, and extended wear life while eliminating the need for routine maintenance.
