2017 Mini Cooper CV Components
What Are CV Components?
Constant Velocity (CV) components are the unsung heroes of your vehicle's drivetrain. Found on virtually every front-wheel-drive car and on many all-wheel-drive and rear-wheel-drive vehicles as well, these parts are responsible for transferring engine torque to the wheels at a consistent rotational speed — regardless of the steering angle or suspension travel. Without properly functioning CV components, even routine acceleration, cornering, or going over a bump can become rough, noisy, or downright dangerous.
The CV system works by connecting the transmission or differential to the drive wheels through a series of precisely engineered shafts, joints, and bearings. Each component in this chain must absorb the constant flexing, vibration, and angular changes that occur as you drive, making material quality and engineering tolerances critically important. Worn or failed CV parts typically announce themselves through a characteristic clicking or popping noise during turns, vibration at highway speeds, or grease leakage from a torn CV boot — all signs it's time to inspect or replace these components.
Exploring the CV Components Category
This category covers the full spectrum of CV drivetrain hardware. The CV Axle Assembly is the most commonly replaced unit — a complete, ready-to-install shaft with CV joints pre-attached at both ends, making it ideal for straightforward replacements. For those working on a more targeted repair or a custom build, the CV Axle Shaft offers the bare shaft, giving technicians and enthusiasts more flexibility. When your vehicle uses a longer axle arrangement routed through the engine bay, the CV Intermediate Shaft serves as the critical bridge between the transmission and the outer axle. The CV Axle Support Bearing Bracket keeps intermediate shafts properly aligned and reduces vibration transfer to the chassis — a small part with a big impact on ride quality. Finally, individual CV Joints allow for targeted repairs when only the joint itself has failed, without replacing the entire axle.
Top Brands in CV Components
GSP North America is the dominant name in this category, offering one of the broadest selections of CV axle assemblies and shafts on the market. GSP is known for its extensive vehicle coverage and stringent remanufacturing and new-part quality standards, making them a go-to choice for professional technicians and DIYers alike.
TrakMotive has built a strong reputation by focusing specifically on CV drivetrain components, offering both new and remanufactured assemblies with a focus on fit, finish, and reliable performance across a wide range of import and domestic vehicles.
Moog Chassis Parts brings its legendary chassis engineering expertise to the CV components space. Moog is widely trusted by professional mechanics for problem-solving designs and high-quality materials that often meet or exceed OEM specifications.
ACDelco is General Motors' own parts brand, delivering OE-grade CV components that are engineered to the exact tolerances required for GM vehicles — making them a natural first choice for Chevy, Buick, GMC, and Cadillac owners.
Motorcraft is Ford's factory parts brand, providing CV assemblies and shafts designed and validated specifically for Ford, Lincoln, and Mercury vehicles, ensuring direct-fit installation and OEM-level reliability.
Choosing the Right CV Component
- New vs. Remanufactured: New units offer the longest service life; remanufactured parts can be a cost-effective option when sourced from reputable brands with quality controls.
- Complete Assembly vs. Individual Parts: A full CV axle assembly is fastest to install; individual joints or shafts suit those doing targeted repairs or custom work.
- OEM vs. Aftermarket: OEM-brand parts (ACDelco, Motorcraft) are ideal for factory-spec repairs, while quality aftermarket brands often extend coverage to a broader vehicle range.
- Boot Condition: Always inspect the CV boot when servicing these components — a torn boot leads to grease loss and accelerated joint wear.
