TrueDrive SET-RF28230010-2 Front Upper Ball Joint Set - Left and Right

The TrueDrive SET-RF28230010-2 is a complete front upper ball joint set including both the driver-side (LH) and passenger-side (RH) ball joints. This set is designed as a direct OEM replacement, restoring precise steering geometry and suspension performance to factory specifications.

Ball joints serve as the pivot point connecting the steering knuckle to the upper control arm. Worn ball joints can cause steering clunking, pulling, uneven tire wear, and compromised handling — replacing them in pairs ensures balanced suspension performance and extends the life of surrounding components.
