J.C. Whitney JT282322 Front Lower Ball Joint OEM Replacement 43330-49055

The J.C. Whitney JT282322 is a front lower ball joint designed as a direct OEM replacement, cross-referencing Toyota part number 43330-49055. This ball joint is a critical suspension component that connects the lower control arm to the steering knuckle, allowing the front wheels to move vertically with road contours while responding accurately to steering input.

The ball joint features a hardened ball stud that pivots within a grease-filled socket, sealed with a rubber dust boot to keep contaminants out and lubrication in. This design maintains proper front-end geometry for precise, predictable handling. A worn or failed lower ball joint can cause symptoms such as clunking or creaking noises — particularly at low speeds or during turns — uneven tire wear, and reduced steering accuracy.

Key Features:

• Direct OEM replacement — engineered to match original factory specifications
• Front lower position — fits both driver and passenger sides (RH = LH)
• Restores proper steering geometry and suspension articulation
• Hardened ball stud with sealed, grease-filled socket for durability
• Rubber dust boot protects against dirt, moisture, and premature wear
• Cross-references Toyota OEM part number 43330-49055

Replacing a worn lower ball joint restores factory ride quality, improves steering precision, and prevents accelerated tire and suspension wear. This unit is a one-piece assembly ready for installation.
