You can, with the right tools and preparation, but it’s not a trivial job. If you’re comfortable working under a car, handling springs safely, and following a repair manual, you can do it. If you’re new to car repair or your vehicle has advanced features such as ADAS, consider professional help to avoid safety risks and ensure proper alignment.
What the job involves
Replacing front struts changes the ride quality and handling of your vehicle. Many cars use MacPherson struts that combine a shock absorber with a coil spring; some replacements come as complete assemblies with the spring already attached. After replacement, most cars require a wheel alignment, and newer vehicles with sensors may need calibration so advanced safety features work correctly.
Assessing readiness and vehicle specifics
Before you start, honestly assess your mechanical skill, the availability of a safe workspace, and whether your car uses a conventional strut with a separate spring or a pre-assembled strut assembly. Vehicles with all-wheel drive, complex subframes, or ADAS sensors increase the risk of improper installation or misalignment if you DIY. If you’re uncertain, consult your service manual or a local shop for guidance.
Tools and replacement parts
To complete the job safely and effectively, gather the essential tools and replacement parts listed below. The exact parts depend on your car model and whether you choose to install standalone dampers or complete strut assemblies.
- New front struts or complete front strut assemblies (with springs, mounts, and boots if you opt for a ready-to-install unit)
- New upper strut mounts/bearings and, if needed, new dust boots
- New mounting hardware (nuts/bolts) as recommended by the manufacturer
- Brake line or sensor clamps/retainers that may attach to the strut
- Anti-sway bar link kit or links if the old ones are worn
- Spring compressor (only if you are reusing coil springs and not installing a complete assembly)
- Floor jack, jack stands, and wheel chocks
- Socket set, open-end wrenches, breaker bar, and a torque wrench
- Penetrating oil, pry tools, and a breaker bar for stubborn fasteners
- Safety gear: gloves and eye protection
Having the right tools makes the job safer and more predictable. If you’re installing complete strut assemblies, you may skip using a spring compressor, but you still need to torque bolts to the manufacturer’s specs and follow the correct sequence.
Step-by-step DIY approach (high level)
Below is a high-level overview. Always refer to your vehicle’s service manual for the exact sequence and torque specifications. This outline also emphasizes safety and proper handling of springs if you’re reusing them.
- Park on level ground, engage the parking brake, and chock the wheels. Lift the car with a floor jack and securely support it on jack stands.
- Loosen the lug nuts, then remove the wheel on the side you’re working on.
- Disconnect any sway bar link connected to the strut (if applicable) and unclip any lines or sensors attached to the strut.
- In the engine bay or wheel well, remove the top strut mount bolts, then detach the bottom mounting bolts from the steering knuckle.
- Remove the old strut assembly. If you’re rebuilding with the old springs, carefully use a spring compressor to relieve tension, then transfer the spring to the new damper or rebuild the assembly as needed.
- Install the new strut or complete assembly, threading the top and bottom fasteners by hand first. Reattach any lines, clips, or sway bar links.
- Torque all fasteners to the manufacturer’s specification. Reinstall the wheel, lower the car, and torque the lug nuts to spec.
- Repeat on the other side if you’re replacing both sides. After the job, drive gently to settle the suspension before any road testing.
This outline provides a general approach. Your exact steps may vary based on the car’s design, whether you’re using separate dampers or complete assemblies, and whether the vehicle has additional components in the suspension area.
Costs, time, and safety considerations
Expect to spend on parts and tools, plus potential professional alignment if you DIY. Prices vary widely by vehicle and brand, but you may see: parts ranging from about $50 to $300 per corner for dampers or $150 to $500 per corner for complete assemblies, depending on whether you choose OEM or aftermarket options. If you perform the job yourself, plan for several hours per side, with a realistic total of 4–8 hours for a typical two-corner job, plus time for an alignment. Don’t forget to budget for alignment and, if necessary, sensor calibration on modern vehicles.
When to hire a professional
Consider a pro if your car has ADAS cameras, adaptive suspension, or other electronic systems that require precise calibration after suspension work. If you lack a safe workspace, proper equipment, or experience working with high-tension springs, professional service is the safer and often more cost-effective path in the long run. A shop can also ensure axle alignment and suspension geometry are correct, which directly affects handling and tire wear.
Summary
Replacing front struts yourself is feasible for a confident DIYer who has the right tools, mechanical aptitude, and access to the vehicle’s manual. It involves safely lifting the car, removing the old strut, installing a new unit (or spring-and-damper assembly), and rechecking torque specs and alignment. If you’re unsure about any step, or your vehicle includes advanced safety systems, consult a professional to ensure safety and optimal handling on the road.
