BMW OR MINI COOPER CV AXLE SHAFT ASSEMBLY

What are my CV Axle Shaft Assemblies?

When you’re driving your BMW or Mini Cooper, have you noticed a wobbly or shaking sensation in the steering wheel? How about hearing that funny clicking sound coming from the front wheels as you are turning a corner? Sometimes it can from the back of the car under the same turning situation. That sound is an audible warning to the driver that the CV axles need some attention. CV stands for Constant Velocity shafts or axles. These can also be referred to as half shafts or drive shafts. They are the part of the drive train assembly that transfers power from the engine and transmission to the wheels to make your car move.

When the engine in your vehicle is started and running, it produces energy and motion that needs to be delivered to the driving wheels of the car to make it move. This transfer of power goes thru the transmission and then on to the wheels by way of axles and CV joints.

What happens when the CV Axles start to wear down?

Generally there are four basic parts of a CV axle shaft assembly and they are not complicated to a trained certified mechanic.  They start out with the axle shaft, which is connected to the wheel hub, the CV joints which are attached to the axle shaft and a good amount of grease to keep the CV joints lubricated and a protective rubber boot over the CV to keep the grease in and the dirt out. Some cars have multiple CV axle joints in the drive train assembly. Over time, the most common part to fail is the rubber boot. This will leave a telltale sign of leaking grease in that area. Sometimes when this happens, dirt and other debris can get into the CV joint causing extensive damage.

CV Axle Shaft Assembly Repair or Replacement

Repairing and replacing these parts will require a few specialized tools to reassemble and tighten the bolts to the correct torque. Because of that, it is not recommended for the backyard DIY repair.

Any repairs performed at our shop will include complete installation of all necessary parts. During reassembly, all new parts will be torqued to required specifications. A road test will be done to verify the safety of the vehicle.

Other areas that we will check that are related to the CV Axle Shaft are the suspension system, the wheel bearings and condition of your vehicles tires.

At Beyer Motor Works our certified technicians will make an evaluation on what repairs should be performed to get your BMW or Mini Cooper operating safely again.  Schedule an appointment today!
