Review on Timken SP550307 Axle Bearing and Hub Assembly: Superior Performance for Smooth Axle Operation by Robert Byrd

Took my '99 Yukon (old body style) to line up. The store noticed a failed front wheel bearing and offered to replace it for $475-$350 a part (source unknown) and $125 labor. I went through and bought some stock here. Took an hour to install and it would have taken less if I left the dirt around the hub (like in a shop). After installation, the knock in the front left suspension (when hitting bumps) disappeared! Timken makes great products and although they now ship both overseas and domestically I am very satisfied with their products. A year later everything is still good as it should be!
