Another symptom of a failing rear hub seal is a grinding or whining noise coming from the rear of the car
. This noise is caused by lack of lubrication in the axle components, leading to increased friction and wear. If left unattended, this could eventually lead to axle failure and a costly repair.In addition to protecting against external contaminants, dust wiper seals also help retain lubrication within the system. By preventing dust and dirt from entering the system, these seals help reduce friction between moving parts, which can prolong the life of the equipment and reduce maintenance costs. Proper lubrication is essential for the smooth operation of hydraulic cylinders, pneumatic systems, and other machinery, and dust wiper seals play a vital role in ensuring that lubricants stay where they are needed most.
