The wheel seal is often part of a bearing assembly for the wheel. It performs two critical roles:

  1. The wheel bearing is lubricated with grease. As the wheel rotates, the bearings must be kept lubricated. The seal in the wheel keeps the oil inside the wheel bearing assembly.
  2. The wheel seal keeps water, dirt, and other contaminants from entering the wheel bearing.

The wheel seal protects your wheel bearings from debris and moisture. It’s a large rubber and metal seal that is located in the hub on some vehicles. Depending on the design of the wheel bearing and hub, the wheel seal is installed either:

  • Directly into the hub
  • Onto the spindle

When changing your rear axle wheel bearings, it is always best practice to also replace the accompanying seal. Not only are seals inexpensive in comparison to other parts, but they protect against future damage too. If you think the seal may be going bad, don’t wait–replace it right away to avoid having to change the bearing as well.

Now that we know what they are and what they do, let’s talk about when they should be checked.

  • As a general rule of thumb, you should check your wheel bearing seals every time you change your oil.
  • If you live in an area with a lot of dirt and dust, it’s a good idea to check them more often. The same goes for if you live near the beach as salt water can cause corrosion.
  • It’s also a good idea to check your wheel bearing seals if you notice any strange noises coming from your wheels. These could be signs that something is wrong with your bearings.
  • Further, after changing your tires, it’s a good practice to check the wheel bearing seals to ensure they haven’t come loose.

If you want to know if your wheel bearing seal is any good, one way to determine this is by looking for leaks. If grease is dripping, it means the seal has been damaged and should be replaced immediately.


The majority of the wheel-bearing seals are made of rubber. Because to heat, friction, and the elements, this rubber might deteriorate and split over time. Once they’ve been damaged, they can no longer effectively keep foreign bodies out, which may result in more significant difficulties.


If your wheel bearing seal is loose, it’s an indication that it needs to be changed. A leaky seal might lead to contamination and ultimate destruction of your bearings.


It’s critical to keep the soil and grass clean at all times. Grass and dirt can accumulate over time, causing issues. It’s essential to maintain them clean in order to avoid any difficulties.
