This front CV axle shaft assembly set is designed for the left and right front positions on 2004-2010 Toyota Sienna models. Built from alloy steel and carbon steel, it is made to provide durable performance and reliable drivetrain operation. The assembly features OEM-level precision with proper spline alignment for fitment and function. Sealed neoprene boots help protect the joints from dirt, debris, and moisture while pre-greased internals support smooth operation. Pre-installed output shaft nuts and ABS rings help simplify installation.
