Axle Boot (Differential Side) Hyundai i10/Santro

Axle boots (often referred to as CV boots or constant velocity boots) are rubber or silicone covers that protect the CV joints (constant velocity joints) and the axle shafts from dirt, debris, moisture, and other contaminants. These boots are essential for maintaining the proper function and longevity of the axle components in a vehicle’s drivetrain.

Key Functions of Axle Boots:

Protection from Contaminants: Axle boots keep dirt, water, and debris away from the CV joints, which could otherwise cause wear, corrosion, or damage.

Grease Retention: They also help to retain the grease within the CV joint. This lubrication is critical for the joint’s movement and helps prevent friction-related damage.

Flexibility: Since the axle and CV joints need to accommodate movement, the boots are designed to be flexible, allowing for the rotational and axial movement of the driveshaft without breaking or tearing.

Types of Axle Boots:

Inner Axle Boots: Located on the side of the axle nearest to the vehicle's transmission or differential. These boots protect the inner CV joints.

Outer Axle Boots: Positioned near the wheel, these boots cover the outer CV joints, which are responsible for transferring power to the wheels.

Symptoms of Damaged Axle Boots:

Cracks or Tears: If you notice visible damage to the rubber, such as cracks, tears, or holes, the boot can no longer keep contaminants out or grease in.

Grease Leakage: If grease is leaking from the boot, it’s an indication that the boot is damaged or compromised.

Noise: A torn axle boot can lead to a "clicking" or "popping" noise, especially when turning, which may signal damage to the CV joint.

Vibration: Damage to the axle boot and CV joint can cause vibration during acceleration or deceleration.

Importance of Maintenance:

If an axle boot gets damaged and isn’t replaced, dirt and moisture can enter the CV joint, leading to premature wear or failure. This can result in expensive repairs, as replacing a worn CV joint can be costlier than simply replacing a damaged boot.

Axle boots are essential for protecting the CV joints and axle shafts from dirt, water, and debris, while also retaining the necessary lubrication. Regular inspection and maintenance of axle boots are important to avoid more serious drivetrain issues down the road.

Our story began in the 1980's. Back then we were just trading in limited commercial vehicle parts with a single store in Mumbai. Herculean brand powered by MantraTek was established later in the 20's by a team of technocrats with sound knowledge and experience of a decade in development and marketing of Automotive Products. Company which is involved in the manufacturing, distributing, importing, exporting and marketing of various high quality auto components which are available throughout India and also in international markets. Today, we are privileged to connect with millions of customers (directly/indirectly) with exceptional products and a number of dealers across the country. The company has established itself as the preferred supplier for many automotive components worldwide.
