Spohn 743 - Manual (Page 2)

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 the Spohn 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 the Spohn a-arm in to the 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 ball joint mounting bolts.
10. We recommend that you take your vehicle for a front end alignment.
NOTES:
New heavy duty ball joints are available from Spohn Performance (Part# K6462).
New upper a-arm mounting hardware is available from Spohn Performance (Part #
985).
