Keep the front wheel located and your steering precise with the Mevotech Supreme Control Arm with Ball Joint CMS861034, a direct-fit front left upper unit for the 1995-2004 Toyota Tacoma. This Toyota Tacoma control arm ties the wheel hub to the frame and pivots on an integrated ball joint, so a worn joint or tired bushings can show up as clunking over bumps, wandering or loose steering, and uneven front tire wear.
Engineered in-house with application-specific upgrades, Mevotech Supreme arms are built for high-usage commercial and passenger vehicles, SUVs, fleets and working trucks, and Labor Saver designs help make the swap faster.
Sold as a complete front left upper unit. If a worn upper control arm or ball joint is the cause of your symptoms, this replaces it.
