The best way to diagnose if this is the cause of your grinding sound is to drive at a low speed with the steering wheel turned fully to the right, then fully to the left. If the grinding or knocking sound is louder with the steering wheel turned in one direction and not the other, a worn wheel bearing is likely your culprit.

Side grinding wheel having a diameter, thickness and hole with one side straight or flat and the opposite side recessed. This type, however, differs from Type 5 in that the grinding is performed on the wall of the abrasive created by the difference between the diameter of the recess and the outside diameter of the wheel.

A v-belt is a flexible and efficient power transmission device capable of transferring power from one shaft to another. It is known for its trapezoidal shape that wedges securely into the sheaves of a shaft. The unique shape of V-belts helps them fit tightly and snugly into the grooves of a sheave, giving them additional surface contact and ...

Associate Editor, Modern Machine Shop. On its surface, grinding seems simple: a machine takes a rotating tool (usually a wheel) with abrasive grains and applies it to a workpiece's surface to remove material. Each grain is its own miniature cutting tool, and as grains dull, they tear from the tool and make new, sharp grains prominent.
