UPPER PRO TOURING A-ARMS
AA028 – 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
subframe. Remove the shims located between the A-
arm cross-shaft and the subframe 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.
