Ball Joint Front Upper Fits Discovery 3&4 BJ4491 - Selby
Keep your Land Rover’s front suspension strong, stable, and ready for anything with the Selby BJ4491 Front Upper Ball Joint, engineered specifically for Land Rover Discovery 3 and Discovery 4 models. This crucial suspension component connects the upper control arm to the steering knuckle, maintaining precise steering geometry, proper wheel alignment, and smooth suspension travel essential for a heavy 4WD that tows, tours, and handles rugged terrain.
As upper ball joints wear, you may notice clunking noises, vague or loose steering, vibration under braking, or uneven tyre wear. The Selby BJ4491 is designed to eliminate these issues with a heavy-duty forged steel housing, a hardened ball stud, and a precision-machined bearing seat to ensure strength, longevity, and smooth articulation. Its sealed, pre-lubricated design locks in grease and keeps out mud, dust, water, and road debris delivering long-life, maintenance-free performance ideal for Australia’s harsh 4WD conditions.
Built to OEM specifications, the BJ4491 installs as a direct bolt-on replacement, providing perfect fitment with no modifications required. Trusted by 4WD workshops, mechanics, and Discovery owners nationwide, Selby suspension components are known for their durability, precision engineering, and consistent reliability. Whether your Discovery is used for family touring, towing, off-road adventures, or daily driving, the BJ4491 restores safe, stable, and predictable front-end performance.
