How long does it take a mechanic to replace CV joints?
Most shops estimate 1–2 hours to replace a single CV axle on a typical front-wheel-drive car. If you’re replacing both sides, plan for about 2–4 hours, and boot-only work usually takes about 1–2 hours. Complex AWD setups or difficult access can extend the timeline.
What a CV joint replacement involves
The CV joints transfer engine power to the wheels while allowing the suspension to move. Replacing them can mean different jobs depending on the vehicle and symptoms. Some customers opt to replace just the boot if the joint is still good; more often, shops replace the entire half-shaft (the axle that contains the CV joints), which requires removing wheel assemblies, brakes, and the axle from the transmission or differential, then installing a new half-shaft and torquing fasteners to specification.
- Replacing a single CV axle (half-shaft) on one side for a standard front‑wheel‑drive vehicle: typical time is 1–2 hours.
- Replacing both sides (two half-shafts) on the same vehicle: common total time is about 2–4 hours, depending on access and vehicle design.
- Replacing only an outer or inner CV joint without removing the entire axle (less common): commonly 2–4 hours, depending on the joint access and tooling.
- Boot-only repair (replacing a torn CV boot without replacing the joint): usually 1–2 hours if the joint is still in good condition.
In some vehicles, particularly older models or SUVs with tighter clearances or four-wheel drive systems, the process can take longer due to corroded fasteners, more extensive disassembly, or additional components that must be removed.
Typical time estimates by scenario
Below are common scenarios you might see quoted by a mechanic or shop. These are general ranges and may vary by model, shop process, and whether any complications arise.
- Single CV axle replacement on one side (front‑wheel drive): 1–2 hours.
- Both sides replaced on a front‑wheel drive: 2–4 hours.
- CV boot replacement with no joint replacement: 1–2 hours.
- Joint replacement without axle replacement (rare): 2–4 hours.
- All-wheel-drive/high-mileage vehicles with extra disassembly: 3–5+ hours per side.
Time estimates assume standard tools, a typical service bay, and no major complications. If the shop expects to replace the entire axle assembly, they often quote a flat rate per side and may complete the job quicker if parts and access are straightforward.
Factors that influence how long it takes
Several variables can make a CV joint replacement take longer or shorter than typical estimates. Here is a look at the main drivers.
- Vehicle make, model, and drivetrain: Some cars use different hub assemblies or require more disassembly than others.
- Access to fasteners and components: Rusted or seized nuts, corrosion, or limited workspace can slow the job.
- Whether the job is axle replacement vs boot/joint-only work: Boot-only tasks are generally quicker when the joint is still serviceable.
- Whether wheel alignment is needed: Replacing CV joints does not usually require alignment, but some related suspension work can.
- Whether parts are readily available and the shop workflow: If the part is back-ordered or the shop is busy, start times and total duration may shift.
For vehicles with AWD or models that demand extra steps to access the CV joints, plan on additional time—often 1–3 extra hours—especially if hub or differential work is involved.
Special cases: AWD and hard-to-access setups
All-wheel-drive and some trucks present additional challenges. If the axle is connected to the transfer case or requires differential work, or if fasteners are rusty and require more effort, the job can extend by several hours. In extreme cases, technicians may need to remove fuel lines or subframes to gain access.
- Seized or corroded axle nuts requiring more effort to remove.
- Split or nonstandard axle designs that require special tools or methods.
- Need to replace related components (brake lines, wheel bearings) as part of the same service.
These factors can push typical times higher, so it’s wise to get a written estimate that includes potential contingencies.
Summary
CV joint replacement times vary by vehicle and method. Replacing a single CV axle on a standard front‑wheel‑drive car usually takes about 1–2 hours; boot-only work typically runs 1–2 hours; both sides or more complex scenarios can take 3–5 hours or more. Always expect some variation due to access, rust, AWD configurations, and additional parts that may need replacement during service. Check with your mechanic for a precise estimate based on your vehicle and symptoms.
How much would a mechanic charge to replace a CV axle?
A shop will likely charge between $300 and $1,500 to replace one CV axle, though the total cost can range from $200 to over $600 for some common vehicles. The final price depends on the vehicle's make and model, with luxury or performance cars costing more, and factors like labor rates in your area.
Factors that influence the cost
- Vehicle make and model: Parts for common cars like a Honda Civic are much cheaper than for a luxury vehicle like a BMW or a high-performance sports car.
- Labor costs: This is often the most significant part of the cost. It can vary by shop and location, and some vehicles require more complex or time-consuming work.
- Type of part: You can choose from different quality levels of replacement axles, from cheap aftermarket parts to more expensive OEM (original equipment manufacturer) parts.
- Condition of the vehicle: If there is significant rust or other complications, the labor time will increase, raising the final price.
How to estimate the cost
- For a common, non-luxury vehicle: Expect the total to be in the $300–$600 range for one axle, as parts are typically $90–$150 and labor is around 1.5–3 hours.
- For a luxury or performance vehicle: The cost will be much higher, with a single axle replacement possibly costing over $1,500.
- For a dealership: Expect to pay about 40% more for labor than at a trusted independent mechanic.
Tips to save money
- Shop around: Get quotes from a few different mechanics to compare prices.
- Bundle repairs: If you also need other work done, like a brake replacement, see if you can get a discount by doing the CV axle replacement at the same time.
Is a CV joint a big job?
However, it's essential to acknowledge that replacing a CV joint is a complex task that requires a high level of mechanical skill, specialised tools, and safety precautions.
Are CV joints hard to replace?
The downside of CV axles is that they are slightly more complicated than the old style, but the upside is that replacing an axle on one wheel is possible.
How many hours does it take to replace a CV joint?
1.5-3 hours
All automotive services have two main costs, parts, and labor. Labor cost is what you pay a shop, which in turn pays its technicians, to perform the service or repair. Labor rates vary from shop to shop but normally it will take 1.5-3 hours to replace a CV axle depending on the make and model of the vehicle.
