Article 969 - Availability of Steering Shock Absorber Damper Kit

TSB #56 - December 16, 1966
(1966-67 Bronco and F-100 4x4)


This announces the availability of a steering shock absorber damper kit, C6TZ-3E650-A, which has been released as a service part for the subject vehicles. The kit consists of a shock absorber type vibration damper and the necessary hardware to attach the shock absorber to the drag link and the frame #1 cross-member.

The kit is for use in situations where the owner complains of wheel shimmy, shake or steering wheel kick. While it is recognized that such a complaint is unrelated to the driver's effective control, the condition can interfere with the driver's enjoyment of the vehicle.

The kit installation procedure is the same for both the Bronco and F-100 4 x4 except for the exact mounting location of the steering shock absorber damper kit. The procedure is as follows:

    1. Inflate the tires to 30 PSI front and rear on passenger type tires (up to 4 ply) and 45 PSI front and rear on truck type tires (6 & 8 ply).
    2. Install the front tires on the rear and the rear tires on the front. If an off road type tread is used only on the rear, then switch the front tires from side to side.
    3. Check toe-in. Adjust to specification 1/8" toe-in.
    4. Adjust the steering gear preload. The specification is 5 inch pounds on the worm and 16 inch pounds across the high point in the gear. It is absolutely necessary to disconnect the pitman arm to obtain the proper readings.
    5. Install the shock absorber kit C6TZ-3E650-A as follows:
      A. For the F-100 4 x 4 installation, use Illus. S1157-A, and for the Bronco, use Illus. S1158-A.
      B. Arc weld all four sides of the "T" mounting bracket to the number one cross-member and bolt the "L" shaped bracket to the drag link as shown in the respective figures.
      C. Install the shock absorber as shown in the respective figures. Attach the rod end of the shock absorber to the bracket bolted to the pitman arm end of the drag link. Attach the body end of the shock absorber to the bracket welded to the crossmember. Upon completion of the installation, make the following checks:
Bronco
Check for 3/4 inch minimum clearance between the drag link bracket and the pitman arm in a full left turn and a 7/8 inch minimum clearance between the drag link bracket and the number one crossmember on a full right turn. If necessary, rotate the drag link bracket downward to provide minimum clearance at normal ride height. A minimum of 1/8 inch must be cut off threaded ends of the "U" bolts to provide the minimum clearance. Torque all nuts to specification as shown on the figure.

F-100 4 x4
On some 1966 F-100 4 x 4 units, the drag link was revised in production. Before this kit is installed on a 1966 F-100 4 x 4, be sure the adjustable end of the drag link is attached to the pitman arm. This is necessary to obtain proper clearances when the Shock Absorber Damper Kit is installed.

Check the clearance between the drag link bracket and the pitman arm in a full left turn. If necessary, rotate the drag link bracket downward to provide 1/2 inch minimum clearance to the pitman arm in a full left turn at normal load. A clearance check in a full right turn should show the drag link bracket to be below the upper edge of the drag link. The "U" bolts should clear the shock absorber by 1/16 inch in a full right turn. Grind the "U" bolts ends if required to provide clearance. Torque all nuts to the specification shown on the figures.
