Ball Joint Fits Ford Focus 21mm BJ Pin Taper 03/06-06/12 BJ4387 - Selby
Restore the sharp, stable and predictable handling your Ford Focus is known for with the Selby BJ4387 Front Lower Ball Joint, engineered to suit Ford Focus models built from March 2006 to June 2012 featuring the 21mm BJ pin taper. As a vital suspension component, this ball joint connects the lower control arm to the steering knuckle, maintaining correct wheel alignment, smooth suspension travel and precise steering response essential for compact cars designed for agile city driving and balanced highway performance.
Over time, factory ball joints wear due to constant articulation, braking forces, potholes and everyday road vibration. When worn, you may notice clunking noises over bumps, vague or wandering steering, vibration through the steering wheel or uneven tyre wear. The Selby BJ4387 eliminates these issues using a heavy-duty forged steel housing, a hardened 21mm ball stud, and a precision-machined bearing seat, ensuring long-lasting durability and smooth movement. Its sealed, pre-lubricated design keeps grease inside the joint while keeping out dust, dirt, water and contaminants delivering dependable, maintenance-free reliability ideal for daily commuting and high-kilometre use.
Manufactured to strict OEM specifications, this ball joint installs as a direct bolt-on replacement, ensuring perfect fitment with no modifications required. Trusted by mechanics, workshops and Ford owners across Australia, Selby suspension components are known for their strength, accuracy and long service life. Whether your Focus is a daily commuter, learner car or well-maintained family vehicle, the BJ4387 restores safe, tight and confident front-end handling.
