Restoring a 1964 Chevy II (also known as the Nova) often involves rebuilding the front suspension. Having an exploded view of the front suspension parts is essential for proper disassembly, inspection, and reassembly. This guide breaks down the components of the 1964 Chevy II front suspension, explains how they fit together, and offers practical tips for a successful rebuild.
Understanding the 1964 Chevy II Front Suspension Layout
The 1964 Chevy II uses an independent front suspension with upper and lower control arms, coil springs, and a steering knuckle assembly. The system is designed for durability and ease of service, but after decades, parts wear out. An exploded view helps you visualize every component’s role and order.
Complete Exploded View Parts List
Below is a numbered list of the main front suspension parts for a 1964 Chevy II. Use this as a reference when ordering replacement parts or disassembling your car.
1. Upper Control Arm
The upper control arm connects the frame to the steering knuckle via a ball joint. It pivots on a cross shaft with bushings. The arm has two mounting points: the inner pivot (bushings) and the outer ball joint.
2. Lower Control Arm
The lower control arm is larger and carries the coil spring. It also has an inner pivot with bushings and an outer ball joint. The spring sits between the lower arm and the frame.
3. Coil Spring
A heavy-duty coil spring supports the vehicle’s weight. It sits on the lower control arm with a rubber isolator at the top and bottom. The spring must be compressed safely during removal.
4. Shock Absorber
The shock absorber is mounted between the lower control arm and the frame. It dampens oscillations. On a 1964 Chevy II, the shock is located inside the coil spring.
5. Steering Knuckle (Spindle)
The steering knuckle attaches to the upper and lower ball joints. It supports the wheel hub and braking components. The knuckle also provides the steering arm connection.
6. Upper Ball Joint
The upper ball joint is pressed into the upper control arm and bolts to the steering knuckle. It allows vertical movement and steering rotation.
7. Lower Ball Joint
The lower ball joint is also pressed into the lower control arm and connects to the knuckle. It carries more weight and often wears faster.
8. Sway Bar (Stabilizer Bar)
A sway bar is attached to the lower control arms via links. It reduces body roll during cornering. The bar mounts to the frame with bushings.
9. Sway Bar Links
Short links connect the sway bar to the lower control arms. They have bushings at each end.
10. Control Arm Bushings
Both upper and lower control arms have inner pivot bushings. These are usually rubber or polyurethane. Worn bushings cause alignment issues.
11. Bump Stop
A rubber bump stop on the lower control arm prevents metal-to-metal contact when suspension bottoms out.
12. Steering Linkage Components
Though not part of the suspension itself, the steering linkage (tie rods, pitman arm, idler arm) connects to the steering knuckles. An exploded view often includes these for context.
How to Use an Exploded View for Reassembly
Before starting, obtain a factory service manual or a high-resolution diagram. The exploded view shows the sequence: inner bushings pressed into control arms, ball joints installed, control arms bolted to frame, then spring and shock assembly. Follow these steps:
- Disassemble with care: Note the orientation of all parts. Mark or photograph each step.
- Inspect every part: Check for cracks, wear, or corrosion. Replace bushings, ball joints, and shocks as a set.
- Use proper tools: A spring compressor is mandatory for coil spring removal. A ball joint press helps replace pressed-in joints.
- Torque to spec: Use a torque wrench for all fasteners. The factory specifications are in the service manual.
- Align after assembly: Any suspension work requires a professional alignment.
Common Parts Replacement Tips
Upper and Lower Ball Joints
Ball joints are wear items. For a 1964 Chevy II, replacement ball joints are widely available. Check if they are riveted or bolted; original rivets must be drilled out.
Control Arm Bushings
Polyurethane bushings improve handling but transmit more road noise. Rubber bushings provide a stock ride. Both require pressing out and in.
Coil Springs
If the car sits low or sags, springs may have weakened. Replace in pairs. Use a spring compressor and safety stands.
Shocks
Consider upgraded shock absorbers for better damping. Gas-charged shocks are a common upgrade.
Final Recommendation
For a complete exploded view with part numbers, refer to the 1964 Chevy II Factory Assembly Manual or a reputable restoration parts catalog. These diagrams are indispensable for identifying each component and its correct orientation. When rebuilding the front suspension, replace all wear items simultaneously—ball joints, bushings, springs, and shocks—to ensure proper geometry and safety. Always use quality parts from trusted suppliers, and don’t skip the alignment. With an exploded view and careful work, your 1964 Chevy II will ride and handle like new.
