Installation Notes and Tips

Confirm the vehicle is a 1987-1990 Mitsubishi Van with the front upper ball joint application before installation. Inspect the mating suspension components, mounting holes, and tapered stud seat for wear or damage, and replace any worn hardware surfaces as needed. Because this is a bolt-on design with a tapered stud, proper torque and alignment procedures should be followed during service.
