Remove and replace the steering damper (shock absorber) on a 1966 Chevrolet Corvette to restore proper steering dampening and eliminate shimmy or vibration in the steering system.

Warnings

Tools required

Parts

• Steering damper × 1 — Use OEM specification
• Mounting hardware kit (if corroded) × 1 — Use OEM specification

Preparation

1. Park vehicle on level, stable surface and engage parking brake
2. Place wheel chocks behind rear wheels
3. Raise front of vehicle with floor jack at frame crossmember
4. Support vehicle with jack stands under frame rails behind front wheels
5. Spray all steering damper mounting fasteners with penetrating oil and allow 10-15 minutes to soak if fasteners show rust or corrosion

Procedure

1. 1

   Locate the steering damper
   Position yourself under the front of the vehicle with adequate lighting. The steering damper is mounted horizontally between the frame and the steering linkage center link, typically on the driver's side. It resembles a small shock absorber with mounting brackets at each end. Verified detail (Part number hints reference 'OEM specification' generically. Since the 1966 Corvette did not include a factory steering damper, no genuine OEM part number exists; replacement units would be aftermarket and require direct manufacturer documentation to verify fitment.): Verify fitment with aftermarket supplier documentation; no factory OEM steering damper part number exists for this vehicle.
2. 2

   Remove the frame-side mounting bolt
   Using a 1/2" wrench on the bolt head and a 9/16" wrench on the nut, remove the upper mounting bolt that secures the steering damper bracket to the frame rail. The bolt passes through the damper mounting eye and a bracket welded or bolted to the frame. Support the damper with your free hand to prevent it from hanging by the lower mount.
3. 3

   Remove the linkage-side mounting bolt
   While supporting the steering damper, use a 1/2" wrench on the bolt head and a 9/16" wrench on the nut to remove the lower mounting bolt that secures the damper to the center link or relay rod bracket. The damper is now free and can be removed from the vehicle.
4. 4

   Inspect mounting hardware and brackets
   Examine both mounting bolts, nuts, and washers for thread damage, excessive corrosion, or deformation. Check the frame bracket and center link mounting tabs for cracks or elongated mounting holes. Clean all mounting surfaces with a wire brush if they show surface rust or debris buildup.
5. 5

   Compare old and new dampers
   Place the old steering damper next to the new unit and verify that compressed and extended lengths match, mounting eye diameters are identical, and mounting eye spacing is the same. The damper should be a direct replacement requiring no modifications.
6. 6

   Install new damper to center link
   Position the new steering damper with the lower mounting eye aligned to the center link bracket. Insert the mounting bolt through the bracket and damper eye, install the washer and nut, and hand-tighten only at this stage. The damper should pivot freely on the bolt.
7. 7

   Install damper to frame bracket
   Swing the upper end of the damper to align with the frame mounting bracket. Insert the mounting bolt through the frame bracket and damper eye, install the washer and nut, and hand-tighten. Verify that the damper is positioned correctly with no binding or interference with other steering components.
8. 8

   Tighten mounting fasteners
   Tighten both the upper (frame-side) and lower (linkage-side) mounting bolts securely. While factory torque specifications are not available in the database, tighten both fasteners firmly using a 1/2" and 9/16" wrench until the damper mounting eyes are snug against the brackets without crushing the bushings. The damper should still pivot with moderate effort at each mount.
9. 9

   Verify damper operation
   Manually cycle the steering damper by pushing and pulling on its body. It should provide smooth, consistent resistance in both directions without binding, leaking, or making noise. Inspect both mounting bolts to ensure they remain tight.

Reassembly

1. Remove jack stands and carefully lower vehicle to the ground
2. Perform final visual inspection of all steering damper mounting hardware from multiple angles to confirm proper installation
3. Test drive vehicle at low speed in a safe area and verify steering feel and response before returning to normal operation

Verification

• Visually confirm both mounting bolts are installed and tight with no gaps between damper eyes and mounting brackets
• Verify the steering damper has no fluid leaks around the shaft seal
• Turn steering wheel lock-to-lock while stationary and verify smooth operation with no binding
• Road test at speeds up to 45 mph on smooth pavement and verify elimination of steering shimmy or vibration that prompted replacement
• Recheck both mounting bolt tightness after first 50 miles of driving
