Which of the following statements about tapered wheel bearings is false?

The assertion that tapered wheel bearings are mostly used on drive axles is misleading because tapered roller bearings are primarily utilized in various applications, with a notable presence in wheel bearings, especially for non-drive axles, like front steering components in some vehicles. They are well-suited for handling both radial and axial loads, which makes them ideal for wheel applications, but they are less common on drive axles compared to other types of bearings such as ball bearings or cylindrical roller bearings.

In contrast, the other statements reflect proper practices and principles associated with tapered wheel bearings. Bearings and outer races being replaced as an assembly ensures that parts maintain their original fit and function, thus preventing premature wear. Adjusting them post-installation is critical for ensuring the proper preload, which affects bearing life and performance. Lastly, reusing used bearings on their original races helps preserve the seating surface and prevents misalignment or failure, as bearings can wear fit to their corresponding race.
