Remove the front wheels.
Remove Cotter Pins
Our main objective is to detach the l ower control from the spindles. In order to do that we
will need to unfasten the lower ball joint castle nut. The first step in doing this is to remove
the cotter pins using dikes or pliers.
4F
5F
Loosen Lower Ball Joint Ca stl e Nut
Once the cotter pin is out of the way, use a wrench to loosen the castle nut. DO NOT undo
the castle nut completely. Just loosen the nut so there is 3-4 threads showing between the
bottom of the nut and the spindle. This gap will allow you to break the taper loose without
launching the lower control ar m down and sending the spring airborne.
Disengage Ball Joint Taper
The lower ball joint stud is tapered and seats inside the spindle mount. It will take a certain
amount of impact to break this taper seat loose. Do so by using a large ball peen hammer
and smack the spindle mount until the ball joint breaks loose. This may take quite a few tries,
but it will eventually break loose. Spray penetrating oil on the stud/spindle mating surface to
ease the process. Once the taper seat breaks loose you will hear the lower arm pop and the
load from the spring is resting on the castle nut.

Support the lower arm and remove Nut
Place a jack underneath the lower control arm and jack up to support the force from the
spring. You should see the castle nut ri se and you should be able to remove the nut by hand .
Remove the spring
Slowly lower the jack which will swing the lower arm down and release the coil spr ing.
Install New Droop Stop
The Hotchkis spring is a bit shorter in height compared to stock. This requires a taller droop
stop to be installed on the upper a-arms to prevent the coil from disengaging from the
mounting pocket during full droop. Undo the stock droop stop and replace i t wi th the s upplied
Hotchkis droop stop.
9F
Install Hotchkis Coils
Install the coil spring in the same manner as stock removal. Make sure to clock and index the
bottom coil in the lower control arm properly. You also want to make sure the upper coil is
seated in the top pocket properly as well. If you have our Hotchkis Lower Control Arms
(#11390L), make sure the upper coil is seated properly and the lower polyurethane isolator is
clocked properly in the Hotchkis arm.

Raising Car
Raise the vehicle using a lift or floor jacks at the rear frame points. It is important that you do
not jack up the truck from the rear end differential. Use chocks for the front wheels. Raise
the rear of the vehicle until the rear wheels are barely touching the ground. It would be a
good idea to place jack stands under the frame for safety.
Disconnect Rear Shocks
In order to get the springs out we must disconnect the rear shocks from the trailing arms
(Truck Arms) to allow them to droop down enough. Disconnect the lower shock nut located
on the truck arm bracket. You may need to play with the height of the floor jack to relieve
any pulling load the rear end may have on the shocks. To relieve any load on the coils, raise
the floor jack until the rear wheels are barely off the ground
Remove Rear Spring
Each spring has a top and bottom retainer. Undo the bolts that secure these retainers. The
spring should be loose and free from the truck. Keep retainers for reinstallation.
4R
Install Hotchkis Rear Coils
Install the coil spring in the same manner as stock removal. Your kit includes new hardware
for the stock retainers. Always install the split lock washers on the nut side of the nut/bolt
assembly.
5R
*Optional Spacers
Your Hotchkis spring kit comes with optional spacers for the rear coils. If you are prone to
having a load in the bed, then it may be beneficial to use these spacers. The kit has 4
spacers, each ¼” thick. Each spacer will raise the rear of the vehicle by ¼”. You can use up
to 2 spacers per side to give a total lift of ½”. To install, Place the spacers between the coil
spring and the truck arm during procedure step 4R.
