Beware of counterfeit bearings and seals:
Unscrupulous manufacturers are flooding the market with poorly engineered bearings and seals that have been deliberately made to resemble premium quality bearings and seals.
Any of those components failing can cause a total wheel end failure. It is not worth a few dollars saved.
We have taken these bearings and set them in their races. You can actually take a pick and move the rollers in the cage. Some of the rollers were not even touching the race. So, beware of cheap wheel bearings.
