Symptoms and warning signs

When your 2019 Toyota 86 begins to exhibit signs of excessive bouncing, it's often accompanied by a range of other symptoms that indicate a deteriorating suspension system, primarily worn shock absorbers or struts. Recognizing these signs early can prevent further issues and maintain your vehicle's performance.

• Prolonged bouncing after bumps: The most obvious symptom, where the car continues to move up and down two or more times after encountering a dip, speed bump, or uneven road surface.
• Reduced ride comfort: The ride feels harsher, and minor road imperfections are felt more acutely, or conversely, the car feels overly soft and wallowy.
• Poor handling and stability: The vehicle may feel less stable, especially when cornering, exhibiting excessive body roll, or swaying. Steering response can become vague.
• Nose-diving during braking: The front of the car dips excessively when the brakes are applied.
• Squatting during acceleration: The rear of the car sags noticeably when accelerating rapidly.
• Uneven tire wear: Specifically, "cupping" or "scalloping" patterns on the tires, where the tread wears in alternating high and low spots. This is a tell-tale sign of a wheel bouncing excessively.
• Fluid leaks from shocks/struts: Visible oil or hydraulic fluid on the exterior of the shock or strut body, indicating a failed seal.
• Visible damage: Bent or corroded shock rods, broken mounting points, or torn dust boots.
• Vehicle "bottoming out": The suspension compresses completely, causing a harsh thud when driving over larger bumps or dips.
• Increased stopping distances: A compromised suspension can reduce tire contact with the road, leading to longer distances required to bring the vehicle to a stop.

How to verify and confirm the issue

Confirming that worn shock absorbers or struts are the cause of your 2019 Toyota 86's excessive bouncing involves a combination of practical tests and visual inspections.

• The "Bounce Test": This is a simple, effective test you can perform yourself.
  • Park your 86 on a level surface.
  • Go to each corner of the vehicle, push down firmly on the fender or bumper, and then release quickly.
  • Observe how many times the car bounces. A healthy suspension should settle quickly, typically bouncing no more than 1-2 times before returning to a stable position. If it continues to oscillate 3 or more times, the shock or strut at that corner is likely worn out.
• Visual Inspection for Leaks and Damage:
  • Park the vehicle and inspect each shock absorber or strut assembly. Look for any signs of hydraulic fluid leaking down the body of the shock/strut. Even a slight film of oil can indicate a failing seal.
  • Check the shock rod for pitting, corrosion, or bending.
  • Inspect the dust boots (if present) for tears or damage, as these protect the rod from debris.
  • Examine the mounting points and bushings for cracks, excessive wear, or looseness.
• Tire Inspection:
  • Carefully inspect all four tires for uneven wear patterns, particularly cupping or scalloping. This distinct wear pattern is a strong indicator that the tire is bouncing excessively due to a failing shock or strut, losing consistent contact with the road.
• Test Drive Evaluation:
  • Drive your 2019 Toyota 86 on various road surfaces, including those with bumps, dips, and curves. Pay close attention to how the car reacts. Does it feel floaty, does it sway excessively in turns, or does it take a long time to settle after hitting an imperfection?
• Professional Inspection:
  • If you're unsure, a professional technician can lift the vehicle, allowing for a more thorough inspection of all suspension components, including sway bar links, control arm bushings, and strut mounts, which can also contribute to poor handling.

Common causes (most likely first)

The primary reason a 2019 Toyota 86 would bounce excessively after hitting bumps almost invariably points to issues within its damping system.

• Worn Shock Absorbers or Struts: This is by far the most common cause. Over time and mileage, the hydraulic fluid inside the shocks/struts can degrade, seals can wear out, and internal valves can lose their effectiveness. This reduces their ability to dampen spring oscillations, leading to excessive bouncing.
• Leaking Shock/Strut Seals: If the seals that hold the hydraulic fluid inside the shock or strut fail, the fluid can escape. Without the proper amount of fluid, the damping capability is severely compromised, resulting in a "dead" shock or strut.
• Damaged Strut Mounts or Bushings: While not directly responsible for damping, worn or broken strut mounts (at the top of the strut assembly) or other suspension bushings can introduce play and noise, further exacerbating the feeling of instability and contributing to poor ride quality.
• Broken Coil Springs: Although less common than worn shocks/struts, a broken coil spring will drastically alter the vehicle's ride height and spring rate at that corner, leading to severe handling issues and potentially bottoming out. While it won't directly cause excessive bouncing in the same way a worn damper does, it will certainly cause abnormal suspension behavior.

Step-by-step diagnosis and fixes

Addressing excessive bouncing in your 2019 Toyota 86 requires a systematic approach to pinpoint the exact problem and implement the correct fix.

• Step 1: Perform the "Bounce Test" on all four corners. As described in the verification section, this quick test helps identify which specific shock or strut might be failing.
• Step 2: Conduct a thorough visual inspection of each suspension component.
  • Look for fluid leaks on the shock/strut bodies.
  • Check for physical damage like bent rods, cracked mounts, or torn dust boots.
  • Inspect all visible bushings (strut mounts, control arm bushings) for cracks, deterioration, or signs of excessive wear.
• Step 3: Examine your tires for abnormal wear patterns. Cupping or scalloping is a strong indicator of a bouncing wheel due to a faulty damper.
• Step 4: Consider your vehicle's mileage and age. Shocks and struts typically have a lifespan, and if your 2019 Toyota 86 has high mileage, they are a prime suspect.
• Step 5: If a worn or leaking shock/strut is identified, replacement is the primary fix.
  • For optimal handling and safety, it's highly recommended to replace shocks and struts in pairs (both front or both rear), even if only one side appears faulty. This ensures balanced damping across the axle. For a sports car like the 86, replacing all four at once can often restore the original handling characteristics most effectively.
  • If replacing struts, consider purchasing complete strut assemblies (quick-struts) as they include the spring and mount, simplifying installation and often saving labor time.
• Step 6: After replacing suspension components, a wheel alignment is crucial. This ensures proper steering geometry and prevents premature tire wear. For more general repair guidance, explore our All repair guides.

Repair options and cost factors

When faced with excessive bouncing due to worn shocks or struts on your 2019 Toyota 86, you have several repair options, each with varying cost implications.

• Shock Absorber Replacement: If your 86 uses separate shock absorbers and coil springs (common on the rear), only the shock absorber itself needs to be replaced.
• Strut Assembly Replacement: For the front suspension, the 86 typically uses a strut assembly, which integrates the shock absorber, coil spring, and strut mount into one unit. You can replace just the strut cartridge (requires spring compressor), or opt for a complete "quick-strut" assembly which is generally easier and quicker to install.
• Parts Quality:
  • OEM (Original Equipment Manufacturer) Parts: These are identical to the parts originally installed on your vehicle and offer assured fit and performance, but are typically the most expensive.
  • Aftermarket Parts: A wide range of aftermarket options exists, from budget-friendly to high-performance. Reputable brands often offer quality comparable to OEM at a lower price. For a sports car like the 86, many owners opt for performance-oriented aftermarket suspension components to enhance handling further.
• Labor Costs: The labor involved in replacing shocks or struts can vary. Struts, especially front ones, often require more labor due to the need to disassemble the assembly or replace the entire unit. An alignment is almost always required after suspension work, adding to the total cost.
• Additional Components: During replacement, it's wise to inspect and potentially replace related components like strut mounts, dust boots, and bump stops, as these wear out over time and are easily accessible during the main repair. For more specific repair information, you can often find detailed guides within our All repair guides.
