Great parts - perfect fit
Got this pair of front wheel bearing assemblies for my 2006 GMC Envoy that was making noise and ABS was coming on a low braking speeds. Parts were a perfect fit and solved the problems. Now a quiet ride and no premature ABS engagement. Great price and quick delivery.

2003 Trailblazer Ext Wheel Hubs
For years I’ve been watching 1A auto videos on YouTube in order to figure out how to fix things on my cars. I always said I would buy some parts from you and try them out as a sort of payback for all the great free info. Finally I needed to replace the wheel hubs for this vehicle and I realized the parts were much cheaper at 1A so I bought them and followed the excellent video instructions. It was a piece of cake and worth every penny. Thanks for creating those great videos and making them accessible to everyone (even if they don’t buy your parts). It’s been a huge help to me and the quality of the parts I bought were excellent as well. Keep up the great service! Kind regards, Joe St. Ours

Where our these made?
Cheryl C on Oct 31, 2017
BEST ANSWER: I bought and installed these with the help of the videos. They work better than the OEM. Who cares where they are made. Seriously, easy to instal, work better than advertised. Incredible price. No reason to care if they come from high dollar union labor or sweat shop in India.
Will these fit my 04 Chevy trailblazer? It is the v6 4.2l and is 4x4 but is not all time 4x4!
Mikey on Dec 15, 2016
BEST ANSWER: This will fit your model application as shown. You have CV axles on the front so you need the splined hubs on the front for your 4WD/AWD system to operate. Engine size is not relevant here
Will this fit the v8 chevy trailblazer model?
Doug G on May 19, 2016
BEST ANSWER: Yes, this will fit the 2002-2009 Chevy Trailblazer, it is not specific to engine size.
