Frequently Asked Questions

What is the drivetrain and why are these parts important?

The drivetrain is the group of components in a vehicle that delivers power from the transmission to the wheels. Key parts include the drive shaft, axles, CV joints, and differential. These parts are critical because they manage torque and rotation, ensuring the wheels receive power efficiently and reliably. Failure in any of these components can lead to a complete loss of mobility.

How do I know if I need to replace my CV axle or axle shaft?

Common symptoms of a failing CV axle include clicking or popping noises when turning, especially at low speeds. A failing axle shaft (often in the rear axle) might present as loud clunking noises, excessive vibration, or visible fluid leaks around the wheel hub or differential. Immediate replacement is recommended to prevent further damage.

What is the difference between an open differential and a limited-slip differential (LSD) like the Truetrac?

An open differential directs power to the wheel with the least resistance, which can cause wheel spin on slippery surfaces. An LSD, such as the Truetrac, automatically biases torque to the wheel with the most traction, significantly improving grip and performance, especially in off-road or high-performance driving conditions.

Are performance axle shafts (like TEN Factory) necessary for daily drivers?

While not strictly necessary for standard daily driving, performance axle shafts offer superior strength and durability. They are highly recommended if your vehicle is frequently used for towing, hauling heavy loads, or engaging in aggressive off-road driving, as they are less likely to bend or snap under extreme stress.

Final Thoughts

Investing in high-quality replacement drivetrain parts is essential for maintaining your vehicle's performance and safety. Whether you need the rugged reliability of a TEN Factory axle for your Jeep, a complete CV assembly kit for your Subaru, or a high-traction differential like the Truetrac, the options listed above represent the best in automotive engineering.
