BBK Performance 25210 User Manual

Gripp Performance Rear Control Arms
Part # 2521, 25210

INS-031

Step 1

Carefully place the rear of your Mustang on jack stands located at the frame locations – not the rear axle.

! CAUTION !

Use extreme caution when working under vehicle

Step 2

Using a hydraulic floor jack, jack the rear axle housing under the center section until the axle reaches approximate
ride height. Place jack stands under the axle for support. (A floor jack will be needed for upcoming steps.)

Step 3

Remove the rear sway bar by removing the two bolts at each side of the bar which attach the sway bar to the
factory control arms.

Step 4

Doing only one side at a time, proceed to lift the rear of the control arm to eliminate any resistance against the
mounting bolts.

Step 5

You may now remove the bolt locating the control arm to the rear axle.

! CAUTION !

Use extreme caution

the control arm is under extreme

pressure from the rear coil spring

Step 6

By carefully and slowly lowering the floor jack, you can now release all spring pressure against the control arm
and remove the rear coil spring. (It is a good idea to mark the coil spring for future installation reference.)

Step 7

Upon removal of the factory coil spring, inspect the rubber insulators and replace with
Ford part # d8bz-5536-A if necessary.

Step 8

Remove the bolt attaching the control arm to the chassis and proceed to remove the rear control arm. (Using
something such as a wire brush, clean the control arm pivot at the chassis.)

Step 9

With the grease fittings pointing down and the sway bar mounting pad towards the front of the car (note that the
sway bar mounting pad should also be offset towards the outside of your vehicle), you can now install the arm by
reinstalling the front bolt. Do not tighten the bolt at this time.

Step 10

Using caution not to damage grease fittings, carefully place the floor jack under the new arm and reinstall the coil
spring with rubber insulators by reversing removal procedure. Repeat for other side.

Step 11

Using a drop of Loc-tite™ on each mounting bolt, torque the control arm mounting bolts to approximately
70 ft lb.

Step 12

Reinstall the sway bar with ends towards the outside of the mounting pad on the control arm.

Step 13

To avoid any squeaking you may now lube the four grease fittings. (Be sure to reinstall dust caps on the
grease fittings.)

Step 14

After driving the vehicle for approximately 5-10 miles, recheck all nuts and bolts for proper torque.
