REMOVAL:
1.
Before starting the installation of your QA1 control arms read the instructions carefully and thoroughly. A good service
manual, available at your local parts store may aid in the installation. Check to make sure all of the parts and tools
needed to complete this installation are on hand.
2.
Jack up the car so that jack stands can be placed under the frame. Let the jack down so that the frame sets securely on
the stands.
3.
Remove the wheels and then unbolt the brake calipers. Secure the brake calipers out of the way of the control arms
(do not let the caliper hang from the brake line. This can cause damage to the brake line). For vehicles equipped with
ABS, refer to your Ford manual for safe removal.
4.
Remove the sway bar end links from the vehicle. (Inspect for bushing wear and replace as needed)
5.
Use the floor jack to support one of the A-arm assemblies. Jack the A-arm up just enough to take the load off of the
strut and spindle. Use of a spring compressor to contain the spring energy is highly recommended. (Fox body cars will
require the removal of the rotor backing plate before continuing.) Remove the cotter pin from the castle nut on the
ball joint. Loosen the castle nut enough to separate the ball joint. Once the ball joint has been loosened from the
spindle the castle nut should be removed. Slowly, CAREFULLY, let the A-arm assembly down until the spring is free and
can be removed.
6.
Repeat this procedure for the opposite side.
