One of the main signs that a wheel hub seal needs to be replaced is the presence of grease around the wheel hub. If you notice grease leaking from the wheel hub area, it is likely that the seal is worn out and needs to be replaced. Another common indication that the wheel hub seal is damaged is the presence of a grinding or squeaking noise when driving

wheel hub seal. This noise is caused by the lack of lubrication in the wheel hub, which can lead to metal-on-metal contact and damage.

Oil seals play a crucial role in the performance and longevity of machinery. Without a properly functioning seal, oil can leak out of the system, leading to inadequate lubrication and potentially causing damage to the equipment. In extreme cases, a leaky oil seal can result in a breakdown of the machinery, requiring costly repairs and downtime.
The manufacturing process of oil seals involves several steps, starting with the selection of the raw materials. Synthetic rubber is the most commonly used material for oil seals, as it offers excellent sealing properties and flexibility
