Perfect fit -good quality - Great Price
My trusted mechanic told me never to buy the cheap bearings, but the ones I paid more than double for broke within 2 years. The sensors went bad. I installed these in just a couple hours with the help of the videos. I could replace these again and still save money. I like the 2 year warranty too. So far they have been great. They seem just as good or better than the expensive ones I bough years ago.

Wheel bearings
These wheel bearings are stout. I have had to use the warranty on one of mine but that was only because the abs connector plug had been crushed and when calling A1 Auto they replaced it with no questions asked and I had it in about three days. The parts come with everything you need to complete the job in its entirety. The bearings are super smooth and tight. You just get the feeling you are holding quality in your hands. The weight of the part tells it all. Great purchase. Would do it again in a heartbeat.

05 trailblazer front hub assemblies.
My daughter and I each have 05 trailblazers with over 100,000 miles. I replaced mine last year. I replaced hers last month. 1aauto has the best price by far for the parts. The video for installation was a very great help and gave me the confidence to do it myself. Parts fit perfectly like oem. I strongly recommend 1aauto for any parts you may need. I know I will come here first in the future. Tim

I installed them on a 2007 Trailblazer. Easy to install. The ABS wire has a good shielding and all of the plastic anchors are included and in the correct location on the wire. Made for a very easy and correct install. The price was great so I purchased the pair, but only had to replace the right side for now. I also like the two year warranty. Had no issues with shipping. This is my second purchase and still happy with the parts received and the packaging of the parts received. Thanks 1A Auto!!!!

Fixed the problem, the real problem
The mechanic diagnosed the correct problem, however he thought it was the other wheel. So, for less than half the price, and an afternoon, I changed both. Originally just the one thought to be bad, which didn't fix the problem. Then the second one which made the vehicle feel and sound like new.

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.
