• Q: How to replace the lower ball joint on 2004 Chevrolet Impala?

  A: The vehicle must lift up and get supported before starting replacement of the lower Ball Joint. The tire/wheel needs removal before drilling a pilot hole through rivets then moving onto the complete drilling of rivets. A combination of hammer and chisel enables users to eliminate rivet heads from the system. Begin by taking off the ball stud's cotter pin before turning the ball stud nut. You should fit the Ball Joint/stud separator (J 41820) between ball stud and lower Control Arm before turning the ball stud nut clockwise to split the ball stud from the Steering Knuckle. To proceed further remove the j 41820 device and detach both the ball stud nut and ball stud from the lower Control Arm. Install the ball stud onto the Control Arm then secure the new bolts underneath with the ball stud directed downward followed by new nuts fastened to 68 nm torque (50 ft. Lbs.). Operating on the ball stud you must install it to both the Steering Knuckle and then tighten the ball stud castle nut to 20 nm (15 ft. Lbs.) followed by an additional 120° angle. Finish the installation by adding a new cotter pin then bending the ends while reinstalling tires and wheels followed by lowering the vehicle before conducting a wheel alignment check.
