Unfortunately I was not able to install it myself because I had no time with my boys. However it has been on the trailblazer for a week now and it is quiet and smooth. Great product.

New Front axle shaft
I found the part to be as advertised however the one piece, that is the axle nut, does not include the integrated washer that is part of the original axle nut. I felt uncomfortable using the new one so I broke the rule and reused the original.
