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

I replaced the left side a few weeks ago and last week the right side broke. 75,000 miles and the OEMs were worn out. These new ones are perfect. Pay extra for Timkens. It's worth the peace. Just make sure you order by VIN. My Tahoe was made in April 1999 and later that year they replaced the part with a newer version. I ordered wrong the first time, had to return. But the last 2 were correct. Brilliant!
