2014-2017 Caprice PPV Strut Guide: Police-Spec Tuning, Noises, and Replacement

Symptoms of a Failing Strut

Because struts wear out gradually, you might not notice the slow decline in ride quality. However, certain distinct signs indicate it's time for a replacement. Many of these symptoms are most noticeable when driving over bumps, turning, or braking.

Noises: Clunking, Knocking, and Squeaking

The most common sign of a bad strut is noise. You may hear a loud clunking or knocking sound when driving over bumps, potholes, or uneven pavement. This is often caused by metal-to-metal contact inside a worn-out strut or, very commonly on this vehicle, a failed upper strut mount. A squeaking or grinding noise when turning the steering wheel at low speeds can also point to a worn or seized strut mount bearing.

Poor Ride Quality and Instability

A vehicle with failing struts will feel unstable and lose its composure on the road. Key symptoms include:

• Excessive Bouncing: The car continues to bounce up and down long after hitting a bump or dip. The suspension should absorb the impact and settle immediately.
• Nose-Diving and Squatting: The front end of the car dips excessively when you apply the brakes, or the rear end squats down during acceleration.
• Swaying or Rolling: The vehicle feels like it's leaning or swaying heavily during turns or even just changing lanes, creating an unsettling feeling of not being in full control.

Visual Signs and Tire Wear

• Fluid Leaks: A strut is a hydraulic component. If you see oily or greasy fluid coating the body of the strut, it means the internal seals have failed and the strut can no longer provide proper damping.
• Uneven Tire Wear: Worn struts can cause a specific type of tire wear called "cupping" or "scalloping." This appears as a pattern of alternating high and low spots on the tire tread, caused by the tire bouncing as it rolls down the road.
• Damaged Strut Mounts: Pop the hood and inspect the top of the strut towers. If the rubber in the strut mount is cracked, separated, or bulging, it needs to be replaced. A gap of more than a quarter-inch between the mount's washer and the strut tower is a clear sign of failure.

Known Issues, Recalls, and Service Bulletins

As of mid-2026, there are no specific recalls or Technical Service Bulletins (TSBs) from General Motors for the struts on the 2014-2017 Caprice PPV. However, several safety recalls were issued for other components on these vehicles, including the electric power steering system and seat belt tensioner cables. While the struts themselves are robust, the upper strut mounts are a known weak point on this platform (shared with the Pontiac G8 and Chevrolet SS), often failing before the strut itself. Additionally, front control arm bushings are another common failure item that can cause vibrations and clunking noises similar to a bad strut.

Buying a Used 2014-2017 Caprice PPV Strut

A high-quality, low-mileage used OEM strut can be an excellent value, often outperforming a cheap new aftermarket part. The original GM struts were specifically tuned for the PPV's demanding police duty cycle. Here’s what to look for:

• Thorough Visual Inspection: Check the strut body for any signs of fluid leaks, which appear as a dark, oily film. Avoid any strut that is wet or covered in grime stuck to oil. Inspect for dents, deep rust, or bends in the strut body or piston rod.
• Check the Strut Mount: If you are buying a complete strut assembly (with the spring and mount attached), pay close attention to the upper mount. The rubber should be intact with no major cracks or separation. Press down on it; it should feel firm, not spongy or loose. A bad mount will cause noise and alignment issues.
• Mileage is Key: Struts are a wear item. A used strut from a vehicle with 50,000 miles is a great find. One from a car with over 120,000 miles is likely nearing the end of its service life and should be avoided unless the price is extremely low.
• Verify the Clevis Design: Some early and late model Caprice PPVs may have used struts with different lower mounting brackets (clevis). One design may be wider than the other. It is critical to visually compare the mounting points of your original strut with the used part you intend to buy to ensure they match.
• Buy in Pairs: Always purchase and replace struts in pairs (both front or both rear). Installing one new or used strut with an old one on the other side will create unbalanced handling, which can be dangerous.

Replacement Overview & Related Parts

Replacing a front strut on a Caprice PPV is a job for an experienced DIYer or a professional shop. It is more involved than simply changing a shock absorber.

Parts to Replace at the Same Time:

To save on future labor costs and ensure the suspension is fully refreshed, it's wise to replace related components at the same time.

• Strut Mounts: A mandatory replacement. New struts on old, collapsed mounts will lead to noise and poor performance.
• Bump Stops & Dust Boots: These protect the strut's piston rod from dirt and prevent it from bottoming out. They are inexpensive and almost always included with new struts or can be purchased separately.
• Sway Bar End Links: These small links connect the sway bar to the strut or control arm. They often wear out and can cause a rattling or clunking noise over small bumps.

Cost Comparison for Caprice PPV Struts

Prices can vary based on brand and whether you buy a bare strut or a complete assembly. Labor costs typically range from 1.5 to 2.5 hours per side.
