The operation of the driveshaft bellow

The wheels turn evenly due to the special design of this element, even despite the presence of an angle between the shafts to be connected. Such an important element simply needs to be protected from dust and dirt; therefore, it is periodically required to replace a driveshaft bellow.

Structurally, these products are nothing more than a protective cover made of rubber and resembling a corrugated pipe. The cover must always be intact so that the mechanism itself does not get dirty, which will lead to a deterioration in its condition. If there is a violation of the integrity of the cover and the presence of splashed grease, the boot will have to be replaced.
