The design must be such that it balances the need for a tight seal with the amount of friction generated during operation. Excessive friction can lead to wear and heat buildup, while insufficient sealing can allow fluid leakage. Therefore, engineers carefully select materials and dimensions to ensure optimal performance.

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.
