Installation Notes and Tips

Installation of the MAS Chassis B9643 ball joint requires pressing the component into the suspension arm due to its press-fit mounting type. Ensure the housing press fit diameter of 42 mm matches the vehicle's suspension arm specifications. Use the included castle nut and cotter pin to secure the threaded stud, verifying proper torque settings according to manufacturer guidelines. Since this ball joint is not greaseable, avoid over-lubrication during installation.
