Inner CV Joint Boot for VinFast VF5 TOK TOK318

Inner CV Joint Boot for VinFast VF5 TOK model TOK318 is an important part of the drivetrain system, designed to enclose and protect the inner CV joint (Inner CV Joint) from dirt, water, mud, and other contaminants from the environment. At the same time, the boot helps retain lubricant grease inside the CV joint, ensuring smooth CV joint operation, reducing friction, and extending the service life of the driveshaft.

On the VinFast VF5, the inner CV joint boot works in sync with the inner CV joint, driveshaft, transmission, wheel hub, and suspension system to transmit torque from the electric motor to the wheels steadily. When the boot remains sealed, lubricant grease stays inside the CV joint, helping the balls and sliding grooves operate smoothly, reducing wear, and ensuring drivetrain performance.

The TOK318 product from TOK is made from high-quality synthetic rubber with resistance to oil and grease, heat resistance, anti-aging, crack resistance, and good elasticity during use. The boot is designed to standard dimensions, fits the inner CV joint snugly, and is easy to install on the VinFast VF5 without modification.

After a period of use, the driveshaft boot may tear, crack, or age due to temperature, the environment, and mechanical impact. When this happens, lubricant grease will leak out, while dirt and water can easily enter the CV joint, causing rapid wear and producing noise when the vehicle accelerates or turns. If not replaced in time, the CV joint and driveshaft may be damaged, significantly increasing repair costs.

The TOK318 product is manufactured to high quality standards, ensuring sealing, durability, and effective protection for the inner CV joint on the VinFast VF5.
