How many hours does it take to replace shocks?
On a typical passenger car, a professional shop usually spends about 2 to 5 hours to replace all four shock absorbers. DIY enthusiasts may spend longer, often 6 to 12 hours depending on experience, tools, and vehicle design.
Replacing shocks is a multi-step process that can vary widely depending on the suspension layout, whether you're replacing individual shocks or entire struts, and whether any parts are seized or corroded. The following guide outlines common timeframes and the main factors that influence duration.
Typical timeframes by job scope
The times below reflect common scenarios for a standard modern passenger car. They assume a normal level of access and typical shop equipment; actual times can be shorter or longer.
- Front axle replacement (shocks or struts on both sides): about 1.5 to 3 hours at a professional shop, depending on whether the struts are replaced as a unit and if an alignment is required.
- Rear axle replacement (shocks on both sides): about 0.5 to 2 hours per axle, depending on mounting design and access.
- Full four-corner replacement (both front and rear): about 3 to 6 hours at a professional shop when replacing all four shocks/struts and handling alignment.
Overall, plan for about 3 to 6 hours to replace all four corners at a shop; replacing only one axle is typically about half to two-thirds of that, depending on the vehicle and whether front struts or rear shocks are more complex to access.
Factors that influence replacement time
These are the key elements that can push the duration up or down beyond typical ranges.
- Suspension design: MacPherson strut setups often take longer per corner than separate shocks on solid axles, due to spring compression and more components.
- Replacement type: Replacing the entire strut assembly is typically faster than replacing only a separate shock, because the spring and mount are integrated.
- Hardware condition: Rusted or seized fasteners, corroded mounting points, or damaged threads can slow work significantly.
- Alignment: Replacing front struts typically requires an alignment, which adds time at a shop.
- Tools and environment: Access to a hydraulic lift, torque specs, spring compressors (if needed) and shop equipment affects speed.
- Experience: A veteran technician will complete the job much faster than a first-time DIYer with basic tools.
Understanding these factors helps set expectations and can guide you toward the most efficient option for your vehicle and budget.
Estimated times by common vehicle types
These estimates help drivers plan when scheduling service and budgeting for labor. Real-world times depend on parts availability and the shop's workflow.
- Compact sedans: typically 1.5 to 3 hours per axle for professional technicians; DIY timelines often 3 to 6 hours per axle.
- SUVs and light trucks: typically 2 to 4 hours per axle for professionals, depending on access and spring/shock design.
- More complex or seized vehicles (older cars, heavy rust): can exceed 4 to 6 hours per axle, or require additional work beyond shock replacement.
Always consult a shop for a written estimate that accounts for vehicle specifics, local labor rates, and any incidental work that may be required.
Summary
Replacing shocks is a variable job that hinges on vehicle design, access, and the condition of hardware. For most passenger cars, expect roughly 2 to 5 hours for a full four-corner replacement at a professional shop, with longer timelines for DIY work or vehicles with difficult fasteners. Getting a clear quote ahead of time helps avoid surprises.
