How Long Does It Take to Replace Shocks and Struts?
Quick Answer
2–4 hours to replace all four shocks and struts at a professional shop. A single axle (front or rear) takes 1–2 hours. DIY jobs take 3–6 hours total.
Typical Duration
Quick Answer
Replacing all four shocks and struts takes 2–4 hours at a professional shop. Front strut assemblies typically take longer than rear shocks because they involve more components. If you are doing the job yourself, expect 3–6 hours depending on your experience and whether you use pre-assembled (quick-strut) units.
Replacement Times by Component
| Service | Professional Shop | DIY |
|---|---|---|
| Front struts (pair) | 1–2 hours | 2–3 hours |
| Rear shocks (pair) | 45 min–1.5 hours | 1–2 hours |
| All four (shocks + struts) | 2–4 hours | 3–6 hours |
| Strut with spring compression | 2–3 hours per axle | Not recommended DIY |
| Quick-strut assembly (pre-assembled) | 1–1.5 hours per axle | 1.5–2.5 hours per axle |
Shocks vs. Struts: What’s the Difference?
Struts are a structural part of the suspension. They combine a shock absorber, coil spring, and upper mount into one assembly. They are most common on the front of modern vehicles and directly affect steering alignment.
Shocks (shock absorbers) are standalone dampers that control spring oscillation. They are typically found on the rear axle and do not bear structural load. Replacing shocks is generally faster and simpler than replacing struts.
Factors That Affect Replacement Time
Vehicle type matters significantly. Trucks and SUVs with body-on-frame designs often have simpler rear shock setups that unbolt in minutes. Cars with MacPherson strut front suspension require more disassembly.
Rust and corrosion can dramatically increase labor time. Vehicles driven in northern climates or coastal areas often have seized bolts that require penetrating oil, torches, or cutting tools.
Spring compression is needed if you are replacing only the strut cartridge and reusing the existing spring. This requires a spring compressor tool and adds 30–60 minutes per strut. Pre-assembled quick-strut units eliminate this step entirely.
Alignment required afterward is a critical step. Any time the front struts are replaced, a wheel alignment is necessary. This adds 30–60 minutes at the shop and $75–$125 to the total cost.
Signs You Need New Shocks and Struts
- Excessive bouncing after hitting a bump (the vehicle continues to oscillate)
- Nose diving during braking or rear squatting during acceleration
- Uneven tire wear especially cupping or scalloping patterns
- Leaking fluid visible on the shock or strut body
- Clunking or knocking sounds over bumps
- Poor handling and increased body roll in turns
- Mileage over 50,000–75,000 miles (typical replacement interval)
Cost Estimates
| Service | Parts Cost | Labor Cost | Total |
|---|---|---|---|
| Rear shocks (pair) | $60–$200 | $100–$200 | $160–$400 |
| Front struts (pair) | $150–$500 | $150–$300 | $300–$800 |
| All four + alignment | $250–$700 | $300–$550 | $550–$1,250 |
| Quick-strut assemblies (pair) | $200–$600 | $100–$250 | $300–$850 |
DIY vs. Professional Shop
DIY advantages: Save $200–$500 in labor. Rear shocks are especially straightforward—usually two bolts per shock. Quick-strut assemblies for the front eliminate the need for a spring compressor.
DIY cautions: Never use a spring compressor without proper training. A compressed coil spring stores enormous energy and can cause serious injury if it slips. Quick-strut assemblies are the safest DIY option for front suspension.
Professional advantages: Shops have air tools, lifts, and experience with seized hardware. They can perform the required wheel alignment immediately after strut replacement.
Tips for a Successful Replacement
- Always replace in pairs. Never replace just one shock or strut on an axle—mismatched damping causes uneven handling.
- Get an alignment after front strut replacement. Skipping this step leads to rapid tire wear and poor steering feel.
- Choose quick-strut assemblies for DIY to avoid the dangers of spring compression.
- Inspect related components while the suspension is apart: sway bar links, ball joints, control arm bushings, and bump stops.
- Torque all fasteners to spec and re-torque after 50–100 miles of driving.
