BMW CV Axle Assembly - NTN 33207637445

Product Information

The CV (Constant Velocity) axle assembly is responsible for transferring torque and rotational power from the transmission to the wheels while allowing for suspension movement and steering articulation. The CV axle consists of a shaft with joints at both ends: a CV joint that connects the axle to the transmission and another CV joint that connects the axle to the wheel hub. This design allows the axle to handle changes in angle and length as the vehicle moves, especially when turning or going over bumps.

• Clicking or Popping Noises: One of the most common signs of a failing CV axle is a clicking or popping noise when turning the vehicle. This noise typically occurs when the CV joint is damaged or worn out, especially during sharp turns.
• Vibration While Driving: A failing CV axle can cause noticeable vibrations while driving, especially at higher speeds. This vibration may indicate that the axle is bent, or damaged, or that the CV joints are worn out.
• Grease Leaks: If the CV axle boot tears or cracks, grease can leak out. You may notice grease on the inside of the wheel or around the CV joint. This can lead to increased wear on the joint due to a lack of lubrication.

About NTN

The NTN Company started when backer, Noboru Niwa, sales company, Tomoe Trading Co., and engineer Jiro Nishizono joined together in designing and manufacturing the first NTN ball bearings, in 1918. Many years later the new head of NTN insisted that manufacturing be located within the same market as it was sold, thus NTN Bearing Corporation of America was created in 1963. Today NTN is proficient in the production of ball bearings, spherical, tapered, cylindrical, needle roller bearings, and automotive constant velocity joints. In fact NTN has the largest share of the global market for axle bearings and is a trusted supplier of OEM (original equipment manufacturer) bearings to many of today’s car manufacturers. NTN’s devotion to high standards has earned the company numerous awards for quality from clients, such as, Caterpillar, Ford Motor Company, Detroit Diesel, Navistar International Corporation, Twin Disc, and Clark-Hurth. Presently, NTN is operating in over 50 facilities globally and is the third largest bearing producer, in the world.
