Is replacing CV joints a big job?
Yes—replacing CV joints is usually a substantial repair that can take several hours per side and may involve replacing the entire CV axle rather than just the joint. The level of difficulty varies with vehicle type, access, and whether the inner or outer joint is affected.
What makes CV joint replacement a big job
Several factors determine whether it's a quick boot swap or a more involved axle replacement, and whether a DIY approach is realistic or a shop visit is wiser.
Typical scenarios by vehicle configuration
- Vehicle configuration: Front-wheel drive (FWD), all-wheel drive (AWD), or rear-wheel drive (RWD) changes access to the joints and whether a full axle replacement is preferable.
- Which joint or method: Outer joints (wheel side) and inner joints (transmission side) have different access challenges; many owners opt for replacing the entire CV axle for reliability and speed.
- Boot vs axle: Replacing a torn boot is a simpler repair if the joint is still in good condition; if the joint is worn, most shops replace the full axle.
- Access and suspension layout: The job often requires removing components like wheels, calipers, rotors, and sometimes parts of the suspension to reach the shaft.
- Corrosion and seized fasteners: Rust can seize the axle and fasteners, increasing time and risk of damage.
- Transmission/axle seal risk: Removing the axle can disturb seals and may require resealing, adding potential for leaks if not done carefully.
- All-wheel-drive complexities: AWD systems may need re-indexing or transfer-case considerations after the axle is replaced.
- ABS/wheel-speed sensor risk: These sensors can be damaged during removal, potentially triggering diagnostics or replacement.
- Tools and space: The job demands specific tools (jack, stands, axle nut socket, pry tools, and sometimes a hub puller) and a workspace with enough room to maneuver a long drive shaft.
In short, the task ranges from a manageable boot-and-liner swap on simpler vehicles to a full axle replacement on cars with cramped or corroded components. Model-specific service manuals are a good guide to exact steps and torque specs.
Time, cost, and what to expect
Below are typical ranges you might encounter, depending on whether a boot is being replaced or the full axle, and on your local labor rates.
- DIY time: Roughly 2–6 hours per side for a capable home mechanic; more time if parts are stubborn or access is tight.
- Shop time: Commonly 1–4 hours per axle, though some vehicles require longer if additional components are involved.
- Parts cost: CV axle assemblies typically run $60–$200 per side for economy cars, and $200–$400+ for many mid-range vehicles; boot kits and hardware are cheaper but may be used in partial-repair scenarios.
- Labor cost: Regional variations apply; typical shop rates range from $70–$120 per hour, with higher rates in major cities or specialty shops.
- Total installed cost: Expect roughly $300–$700 per axle for common cars; AWD or luxury models can push toward $800–$1,000+ per axle, depending on parts and labor.
- Alternatives: Remanufactured or rebuilt axles can lower cost; some shops offer used-axle options, though these carry greater risk of wear or failure.
Costs can vary widely by vehicle and region, so getting a written estimate that itemizes parts and labor is the best way to avoid surprises.
Summary
Replacing CV joints is not a routine or minor maintenance task. For many vehicles it involves substantial disassembly, careful handling of transmission seals and sensors, and a decision between boot-only repair versus full axle replacement. If you’re weighing options, compare model-specific guidance, the shop’s experience with your car, and a clear estimate of parts and labor. A well-informed plan can save time and money while ensuring the repair lasts.
