larger disc brakes with taller spindles.

NOT DESIGNED TO WORK WITH STOCK (STANDARD)
“A” OR “G” BODY SPINDLES.
This is a job for expert mechanics. If you have any questions about front-end work,
please consult the appropriate GM service manual or call Hotchkis Performance.
PLEASE READ THESE INSTRUCTIONS CAREFULLY
BEFORE YOU BEGIN.
Thank you for purchasing Hotchkis Performance products.
1) Raise the front of the vehicle to an adequate working height and support the car securely
on jack stands. Remove the front wheels. Work on one side of the car at a time.
2) Remove the front shocks.
3) Remove the cotter pin and nut securing the outer tie-rod ends to the steering arm and
separate the two. Disconnect the flexible brake line from the caliper. Remove the cotter
pins securing the upper and lower ball-joint nuts and loosen the nuts a few turns but leave
the nuts on the threads of the ball-joints. Separate the two ball-joints from the spindle
(using a separating tool, pickle fork, etc.) until the spring pressure snaps down against the
nuts. With a jack, support the lower A-arm until it is loaded enough to release all pressure
against the ball joint nuts, then remove the upper nut and pivot the upper A-arm out of the
way. Remove the lower ball joint nut and remove the entire knuckle assembly (spindle,
rotor, caliper, etc.)
4) Remove the two nuts that hold the upper A-arm crossshaft to the frame of the car (Note:
keep track of the number of alignment shims and their locations as they will be
replaced in the same manner for a rough initial alignment setting). Remove the upper
A-arm from the vehicle.
5) Carefully lower the floor jack under the lower A-Arm to remove the front springs.
(CAUTION! The stock front springs are very long and may need to be compressed
to remove them.)
