This Vevor CV axle shaft assembly is a 2-piece front left and right replacement pair designed for 1996-2002 Toyota 4Runner models. Built from alloy steel and carbon steel, it is made for dependable power transfer and long-lasting durability. The assembly features OEM-level precision with a 27-tooth input spline and 30-tooth output spline for proper fit and smooth operation. A sealed neoprene boot helps protect the joint from dirt and debris while retaining grease under heat and stress. With the output shaft nut pre-installed, installation is more convenient for replacement work.
