How long does it take to fix a suspension system?
In general, most suspension repairs fall in a 1–8 hour range, with common repairs typically taking 2–4 hours per job. Exact timing depends on the fault, vehicle type, and parts availability.
Beyond the clock, there are many variables that influence the timeline. This article explains how to estimate repair time, what tasks are typically involved, and how to plan your visit.
Factors that determine repair time
Several variables influence how long a suspension job will take. The following are the main ones to consider when planning.
- Nature of the fault: wear, damage, or multiple failing components increase the work required.
- Vehicle design and platform: cars with MacPherson struts are often quicker to service than multi‑link or rear independent suspensions; SUVs and trucks may have heavier springs or subframes that add time.
- Parts availability: parts on hand speed up the job; backordered parts cause delays.
- Access and safety: restricted access or need for undercarriage disassembly adds time; safety concerns can require extra steps.
- Need for alignment or safety checks: any suspension work typically requires wheel alignment.
- Labor rates and shop workflow: experienced technicians can complete tasks faster; tool availability matters.
- Specialized equipment: some tasks require spring compressors or alignment rigs; EVs may require different procedures.
In practice, these factors mean that even identical-looking jobs can end up with different ETAs, especially if parts must be sourced or if an alignment is required.
Common suspension tasks and typical durations
Front shocks and struts
Time estimates for replacing front shocks/struts depend on how many units are being replaced and where on the vehicle the work is done.
- Single front shock or strut replacement: approx. 1–3 hours
- Both front shocks/struts on the same axle: approx. 2–5 hours
- All four shocks/struts (front and rear): approx. 4–10 hours
These times can increase if additional components (springs, mounts, or related hardware) are replaced at the same time or if an alignment is required afterward.
Other suspension components
Replacing other common suspension parts can vary by design and vehicle, but typical ranges are:
- Front control arm replacement: 2–4 hours
- Rear control arm replacement: 1.5–3.5 hours
- Sway bar links replacement: 0.5–1.5 hours
- Coil springs replacement (per axle): 2–5 hours
When multiple components are replaced on different axles or on vehicles with restricted access, total time will be longer and may require staged service or overnight parts delivery.
Diagnostics, planning, and alignment
Before any replacement parts are installed, technicians diagnose the issue, confirm the failed components, and prepare an estimate. Typical diagnostic steps and times include:
- Visual inspection and road test: 15–60 minutes
- Electronic diagnostics or component testing: 30–90 minutes
- Parts sourcing and pre-work planning (if needed): 15–180 minutes
Some shops include diagnostic time in the quoted labor, while others bill separately. Always request a written estimate with a breakdown of labor hours and parts before authorizing work.
What to expect at the shop and planning your visit
The repair workflow typically follows a predictable path, though exact timing varies by vehicle and shop. Here is a common sequence of steps that affects how long the job will take.
- Diagnostic evaluation and scope confirmation
- Parts sourcing and delivery (if not in stock)
- Removal of old components and installation of new parts
- Initial test drive and inspection
- Wheel alignment and safety checks
- Final customer walk-through and warranty review
Most straightforward tasks can be completed in a single day; more complex repairs may require a second day or longer if parts must be shipped or multiple subassemblies are involved. Always confirm ETA and request a written timeline with a detailed labor breakdown.
Summary
Suspension repair timelines vary widely. Replacing common components like shocks or struts on a single axle typically takes 1–3 hours per unit, with larger jobs spanning several hours or more. A full front-and-rear replacement or an overhaul can extend into a full day or longer. To avoid surprises, obtain a written estimate that lists labor hours, parts, and the cost of any alignment, and discuss potential delays up front with your technician.
