How many hours does it take to replace a front axle?
On average, replacing a front CV axle on a typical front-wheel-drive car takes about 1–2 hours per side; replacing a full front axle assembly can run 2–4 hours per side, and on all-wheel-drive systems the job can take 3–6 hours per side depending on access and additional work.
Replacing a front axle is a common repair with time varying by the exact part being replaced, the vehicle’s drivetrain, and how difficult the undercarriage access is. This article breaks down typical timeframes and the factors that influence how long the job will take.
What the job involves
The term “front axle” can refer to different components depending on the vehicle. In most front-wheel-drive cars, the front axle is a CV (constant-velocity) axle or half-shaft. On many all-wheel-drive models, the front axle assembly includes CV joints plus related hubs and sometimes alignment concerns. The complexity of the replacement and the tools required can affect the total time, as can rusted fasteners, seized components, or parts that require additional replacement (such as a hub or bearing).
Time estimates by drivetrain
Below are typical labor time ranges you might see in a shop estimate, depending on whether you’re replacing a CV axle, a full front axle assembly, or working on an AWD vehicle. These are general figures and can vary by model and condition.
- Front CV axle replacement (per axle) on a typical front-wheel-drive car: 1–2 hours.
- Full front axle assembly replacement (per axle) including CV joints and hub on some models: 2–4 hours.
- Front axle replacement on all-wheel-drive vehicles (driveshaft/hub removal, possible differential work): 3–6 hours per axle.
- Additional work that can add time (replacing wheel bearings, steering knuckle, brakes, or performing an alignment): 0.5–2 hours extra depending on the job.
In practice, labor times are estimates and can vary. Rusted fasteners, seized components, improper alignment, and the need to remove other parts can extend the duration.
Factors that affect duration
Vehicle type and drivetrain
Whether the car is FWD, RWD with independent front suspension, or AWD changes the complexity. AWD models may require driveshaft or differential work that adds time.
Access and corrosion
Access to the axle, exhaust components, and the hub area can accelerate or slow the job. Rust and corrosion at bolts and knuckles are common time-adders.
Additional components being replaced
If the hub, wheel bearings, steering knuckle, or brake components must be replaced or resurfaced, the job will take longer than a straight CV-axle swap.
Getting an estimate
Ask for a written estimate that separates parts and labor, and request a per-axle time if you’re only replacing one side initially. If you’re unsure whether you need a CV axle or a full front axle assembly, a technician can confirm based on inspection of the seized joints and related components.
Summary
For most front-wheel-drive cars, plan about 1–2 hours per CV axle and 2–4 hours per front axle assembly. On all-wheel-drive vehicles, the process tends to be longer, typically 3–6 hours per axle, due to additional steps and potential driveshaft or differential work. Always obtain a written, itemized estimate and be aware that rust, seized parts, and extra repairs can extend the timeline. A well-planned repair frame helps minimize downtime and unexpected labor costs.

How much does it cost to replace a front axle?
The average cost to replace a front axle is between $550 and $740, which includes parts and labor. However, this price can vary significantly based on your vehicle's make and model, the specific parts needed, and local labor rates. For example, the total cost for common vehicles like a Honda Civic might be in the $400-$500 range, while a luxury car could be substantially more.
Factors that influence the cost
- Vehicle make and model: Luxury or European vehicles often have higher part and labor costs compared to domestic or Japanese cars.
- Parts: The price of the replacement axle itself can range from around $100 for an aftermarket part to over $1,000 for an OEM (Original Equipment Manufacturer) part, depending on your car.
- Labor: The total labor cost depends on the shop's hourly rate and how long the job takes. The job typically requires 1.5 to 2 hours of labor per side.
- Extent of damage: A simple replacement is cheaper than a job that involves repairing or replacing other components, like a CV joint or a bent axle shaft.
- Additional services: Some repair shops may include a wheel alignment in the total price because the front suspension is often unbolted during the process.
- Warranty: Check if your vehicle is still under a powertrain warranty, which could cover the cost of the replacement.
How long does it take to replace a front axle?
Replacing a front axle typically takes 1 to 4 hours of labor for one side at a professional shop, depending on the vehicle, its condition, and the mechanic's experience. Factors like rust, corrosion, or a need to replace additional parts can increase the time. For a DIY job, it could take an entire afternoon or even longer.
Professional shop
- Labor Time: Most shop estimates fall between 1 and 4 hours for a single axle replacement.
- Factors that increase time:
- Rust and corrosion: Bolts and other components can be difficult to remove in areas with heavy rust.
- Vehicle condition: A car that is older or has been exposed to harsh conditions may take longer.
- Additional repairs: A mechanic might recommend replacing the transmission seal or inspecting other parts, which adds to the time.
DIY (Do-it-yourself)
- Time estimate: A first-time DIYer should be prepared for a longer project, potentially taking an entire afternoon or even a full day or two.
- Factors that increase time:
- Lack of experience: The first time doing the job is often the slowest due to learning the process.
- Missing tools: Not having the correct tools can cause significant delays, as seen in the Quora user's experience.
- Difficulty with components: Stubborn bolts or the need for extra steps can extend the timeline.
Both sides
- Replacing both front axles will not take double the time of a single replacement, as the vehicle is already in a partially disassembled state.
- It may take approximately 3 to 4 hours to complete both sides at a shop.
