8. Using a 15mm and an 18mm wrench, loosen the bolts that hold the upper a-arm
into the factory mounting bracket. Remove the factory a-arm.
9. If you are re-using your factory upper ball joints, you must grind the factory rivets
off of the ball joint and use ¼" bolts to mount it to our a-arm (new aftermarket ball
joints are attached this way as well). Once a ball joint has been installed, keep the
ball joint bolts loose, then bolt our a-arm in to the mounting bracket using the
existing mounting hardware. When installing the a-arms, the curved section of the A-
arm goes towards the front of the car with the ball joint mounting plate at an upward
angle. Tighten the mounting bolts.
10. Tighten the ball joint mounting bolts.
11. We recommend that you take your vehicle for a front end alignment.
Notes:
New heavy duty ball joints are available (Part# K6462).
New upper a-arm mounting hardware is available (Part# 985).
