A very common failure that occurs on your 2nd Gen 5.9L Cummins is the factory wheel bearing assemblies. Especially with the addition of larger, heavy offset wheel and tire packages. The added width creates added stress on the factory bearings. Replace your worn-out wheel bearing and hub assemblies with this replacement from Mevotech. Each wheel bearing features high grade rolling elements and precision polished raceways that minimize resistance and noise. The milti-lipped seals provide a barrier against road contaminants and moisture for a longer life. Everything you need to perform the installation comes with each bearing including hardware and a new ABS wheel speed sensor. Sold individually.
