Symptoms and warning signs

Recognizing the signs of failing struts is crucial for timely replacement and maintaining your Sequoia's performance. Keep an eye out for these common indicators:

• Excessive bouncing or swaying: After hitting a bump, your Sequoia continues to bounce multiple times instead of settling quickly.
• Nose-diving during braking: The front end dips excessively when you apply the brakes.
• Squatting during acceleration: The rear end sags noticeably when you accelerate quickly.
• Rough or harsh ride: Every small bump feels amplified, and the ride becomes uncomfortable.
• Clunking or knocking noises: Sounds coming from the suspension, especially over bumps or when turning, can indicate worn strut mounts or bushings.
• Fluid leaks on the strut body: Visible oil or hydraulic fluid seeping from the strut housing is a clear sign of a failed seal.
• Uneven or premature tire wear: Worn struts can lead to improper tire contact with the road, causing cupping or scalloping patterns on your tires.
• Poor handling and stability: The vehicle may feel less responsive, wander on the highway, or exhibit excessive body roll in turns.

How to verify and confirm the issue

Before you begin ordering parts, it's important to confirm that your struts are indeed the source of the problem. A few simple tests and visual inspections can help you verify the condition of your 2019 Toyota Sequoia's suspension components:

• The bounce test: Push down firmly on each corner of your Sequoia and release. A healthy suspension should rebound once or twice and then settle. If it bounces more than two or three times, the strut at that corner is likely worn.
• Visual inspection for leaks: Carefully inspect the strut bodies for any signs of hydraulic fluid leaks. A thin film of oil is normal, but visible drips or significant wetness indicates a blown seal.
• Check for physical damage: Look for bent strut shafts, cracked or corroded strut housings, or damaged dust boots and bump stops.
• Inspect strut mounts and bushings: Look for cracks, tears, or excessive play in the rubber components of the upper strut mount and any lower bushings.
• Examine tire wear patterns: Uneven tire wear, particularly cupping or scalloping, is a strong indicator of suspension issues. If you notice this, it's a good idea to rotate your tires and have an alignment check after strut replacement.
• Listen for noises: Drive your Sequoia slowly over varied terrain, including speed bumps and rough patches, and listen for distinct clunking, squeaking, or rattling noises that correlate with suspension movement.

Common causes (most likely first)

Struts are wear-and-tear components, and their lifespan is influenced by several factors:

• Age and mileage: This is the most common cause. Over time, the internal components wear out, and the hydraulic fluid degrades, reducing their damping ability. Most struts last between 50,000 to 100,000 miles.
• Harsh driving conditions: Frequent driving on rough roads, potholes, or unpaved surfaces accelerates wear.
• Heavy loads and towing: Regularly carrying heavy cargo or towing trailers puts additional stress on the suspension, leading to premature wear.
• Extreme temperatures: Both very hot and very cold temperatures can affect the seals and fluid viscosity within the struts.
• Impact damage: Hitting curbs or significant road debris can cause immediate damage to struts.

Step-by-step diagnosis and fixes

Replacing struts is a significant DIY project that requires proper tools and safety precautions. This general guide outlines the steps; always refer to your Sequoia's specific service manual for torque specifications and detailed procedures. For more general repair guides, check out our All repair guides.

Tools and Materials You'll Need:

• Jack and jack stands
• Wheel chocks
• Metric socket set and wrenches (including a large socket for the axle nut if replacing front struts)
• Torque wrench
• Breaker bar
• Pry bar
• Spring compressor (if not using quick-struts)
• New struts or quick-strut assemblies
• Penetrating oil
• Wire brush
• Anti-seize compound
• Gloves and safety glasses

General Procedure (Front or Rear Struts):

1. Prepare the Vehicle: Park on a level surface, engage the parking brake, and chock the wheels opposite the side you're working on. Loosen the lug nuts on the wheel(s) to be removed.
2. Lift and Secure: Jack up the front or rear of the Sequoia and place it securely on jack stands. Remove the wheel(s).
3. Disconnect Components:
   • Front: Carefully disconnect the ABS wheel speed sensor wire and brake hose from their mounting clips on the strut. You may need to remove the sway bar end link from the strut body. For front struts, you'll also need to separate the lower control arm from the steering knuckle or remove the lower strut mounting bolts, depending on the design. You might also need to loosen or remove the axle nut and separate the axle from the hub if the lower control arm needs to drop significantly.
   • Rear: Disconnect the brake line and ABS sensor if they are attached to the strut. If it's a separate shock and spring, you'll work with the shock only. If it's a coil-over strut, the process is similar to the front but generally less complex with fewer steering/drive components.
4. Remove Lower Strut Bolts: Support the lower control arm or axle assembly with a floor jack. Remove the large bolts securing the bottom of the strut to the lower control arm or spindle.
5. Remove Upper Strut Mount Bolts: In the engine bay (front) or cargo area/underbody (rear), locate and remove the nuts securing the top of the strut assembly to the chassis. Be prepared for the strut to drop once these are removed.
6. Remove Strut Assembly: Carefully guide the old strut assembly out of the wheel well. This may require some manipulation of the lower control arm with a pry bar.
7. Assemble New Strut (if not a quick-strut): If you're reusing the old spring, use a spring compressor to safely compress the coil spring. Remove the top nut, disassemble the old strut, and transfer the spring, dust boot, and bump stop to the new strut. Install a new strut mount if necessary. Carefully release the spring compressor. This step is dangerous if not done correctly; consider professional help or quick-struts.
8. Install New Strut Assembly: Guide the new strut assembly into place. Start by loosely installing the upper strut mount nuts. Then, align the lower mounting holes and insert the lower bolts. You may need to use the floor jack to raise the lower control arm to align the holes.
9. Reconnect Components: Reattach all brake lines, ABS sensor wires, and sway bar links. Ensure all lines and wires are routed correctly and not pinched.
10. Torque All Fasteners: This is critical for safety. Refer to your 2019 Toyota Sequoia service manual for the exact torque specifications for all strut, mount, and control arm bolts. Tighten all fasteners to spec.
11. Reinstall Wheel and Lower Vehicle: Reinstall the wheel, hand-tighten lug nuts, lower the vehicle, and then torque the lug nuts to factory specifications.
12. Repeat for Other Side: Always replace struts in pairs (front or rear) to maintain balanced handling and prevent premature wear on the new components.
13. Alignment: After replacing struts, a professional wheel alignment is absolutely necessary to ensure proper handling and prevent uneven tire wear.

Repair options and cost factors

When considering strut replacement for your 2019 Toyota Sequoia, you have a few options, each with its own cost implications:

• DIY with Quick-Struts: This is often the most cost-effective option for DIYers. Quick-struts (also known as complete strut assemblies) come pre-assembled with a new strut, coil spring, and strut mount. This eliminates the need for a dangerous spring compressor and significantly simplifies the installation process. Parts typically range from $150-$400 per strut, depending on brand and quality.
• DIY with Component Struts: If you choose to replace just the strut cartridge or body and reuse your existing coil springs and strut mounts, you'll need a spring compressor. While the strut itself might be cheaper ($80-$250), you'll likely need to purchase new strut mounts and bump stops, adding to the cost and complexity.
• Professional Installation: Taking your Sequoia to a professional mechanic means paying for labor in addition to parts. Labor costs can vary widely but typically range from $200-$500 per axle (front or rear) for installation, plus the cost of parts and an alignment. This option offers peace of mind and ensures the job is done correctly.

Cost factors also include the brand of parts (OEM vs. aftermarket), the specific type of strut (e.g., standard, heavy-duty, or those designed for specific suspension systems like TRD), and whether you opt for an alignment immediately after the replacement.

When to see a professional

While replacing struts can be a rewarding DIY project, there are situations where seeking professional help is the wiser choice. If you lack the necessary tools, especially a high-quality torque wrench or a safe spring compressor, a professional can prevent potential damage or injury. The intricate nature of suspension components, particularly the need for precise torque specifications and the danger associated with compressed springs, means that an inexperienced hand could lead to safety issues. Furthermore, if you encounter unexpected complications, rusted or seized bolts, or simply feel uncomfortable at any point during the process, it's best to stop and consult a qualified technician. If you're unsure about tackling this repair, exploring options for various vehicle makes and models can help you find a qualified technician.
