Really wish they would work Rebuilt and installed the bearings on my trailer. One of the sides entered the highway after about 10 km. Lube splattered everywhere and had to end the ride from the other side without protection. I removed them and stuck them back on the original covers. The intervention just wasn't enough. A camp mate said chrome is a better fit than stainless steel, so I suspect they may have a known issue with stainless steel covers. An interference fit may not be sufficient.
