BMR Suspension AA017 User Manual

UPPER A-ARMS

AA017 – 64-72 A-BODY

INSTALLATION:

1. Lift vehicle and support safely with stands under the frame rails. Remove the wheels and tires.

2. Beginning with one side of the vehicle, turn the wheels to allow access to the castle nut on the upper ball

joint.

3. Place a hydraulic floor jack under the lower A-arm and lift slightly to relieve the spring tension from the

ball joint.

4. Remove the cotter pin then loosen the castle nut but do not remove it. Using a brass hammer, hit the

spindle around the ball joint mounting hole until the ball joint pops loose. NOTE: A pickle fork may also

be used to loosen the ball joint.

5. Remove the castle nut then pivot the A-arm upward until the ball joint comes out of the spindle.

6. Remove the two nuts that attach the A-arm to the sub-frame. Remove the shims located between the A-

arm cross-shaft and the sub-frame and set aside in proper order for re-assembly. Slide the A-arm
towards the motor until the cross-shaft clears the mounting studs and remove the A-arm. NOTE: In

some instances, aftermarket headers may need to be removed in order to remove and install the upper
A-arms.

7. Install the BMR upper A-arms over the studs using the original shims. Tighten the nuts.

8. Pivot the A-arm down until the ball joint goes through the spindle. Tighten the castle nut and install a

new cotter pin.

9. Repeat steps 2-8 for the other side.

10. Insert 2-3 pumps of grease into each ball joint.

11. Re-install the wheels/tires. Lower vehicle.
