Awesome fix gooq quality
I compared it to the GM dealer part and was pleased. Great instructions I saved 250 from a local shop and 350 from the dealer. Next time I'm going to change in pairs. Shortly after replacement found the other was defective. The GM part last about 2 years as I use it severe duty plowing, 4wd dirt driveway. In northeast don't be shocked if you need to replace in 2-3 years.

Fast Delivery, No Problems
I had no issues installing this and it's been quiet for about a month now. Just a hint to help you - break the axle nut while the tire is still on the ground. I did and it probably save me a LOT of frustration. The videos I watched did not suggest that, but it would be very difficult breaking that 35mm nut with nothing holding the hub.

Wheel hub bearing replacement
I recently purchased two, front wheel hub bearings for a 2007 Trailblazer. After installing the passengers side bearing I tested the bearing on a short drive that showed everything was virtually the same vibration as before. After I replaced the driver's side bearing I performed a test drive. When I started the vehicle the ABS and Traction Control lights illuminated. After speaking with Mitch at 1AAuto he immediately recommended replacing the hub bearing. He overnighted the replacement at no cost to me and it was installed. They are now both working and there is no more vibration. Thanks 1AAuto!

Hub Assembly
I recently purchased this product from 1A Auto. It was very reasonably priced, and fit the vehicle as expected. I highly recommend 1A Auto to anyone who asks. Additionally, the how-to videos are top rate.

One of 2 came with rough bearings right out of the box. A1 replaced instantly.
Both of the "good" ones lasted just past warranty. Which is probably expected for low cost bearings? Anyway buy low cost bearings with the expectations that they wont last long.
