A very satisfied consumer LRB
I have nothing but good to say about the professionalism of the staff at 1A-Auto.In the past few months I and my family seemed to be hit by the auto Demon.It is bad enough that your vehicle has issues. But when you have to locate parts for repairs it can be very frustrating and expensive. I was very fortunate to locate 1A-Auto on the computer web site. Not only were the ppl I dealt with professional,they were very pleasant and proficient, the prices were very reasonable.also most of the parts I purchased had as life time warranty. They also provided a tracking number of which you could see when and where your parts would be delivered.

Wheel Barring & Hub Assembly
I have purchased several wheel barring from 1A Auto parts due to me having a Ford Explorer. The parts have always been delivered on time and have been quality parts. The prices are very reasonable and I have shared this site with as many women that I can. We need a reliable and honest source to buy parts. If only you could install them??. Overall I’m very pleased??????

Wheel bearing and hub Assembly ford explorer
I have used A1 before to do the upper arm assembly and upper ball joint for my Ford Explorer and the the parts arrived on time and intact. I watched the video on how to replace and completed the job in the estimated time. Sooooo I knew I was going back tot he website when I wanted to replace my front hubs. The video walked me through the installation and the parts matched wonderfully. I would recommend A1 for people who are willing to do the work. Prices are good and the videos are helpful.

Great parts and service
Excellent quality part for reasonable price plus free and fast shipping. The installation video is a big plus also! The Customer service people are professional and accommodating. Easy returns and refund if needed. I was a RockAuto customer for years but 1AAuto has them beat and has my business now.

1A Auto is the way to go for the right parts and very dependable service.
I was greeted on the phone by a knowledgeable staff member who helped me find the wheel bearing for my truck. The price was less than half of most part stores and I received my order in two days. Thank you for getting me back on the road with good quality parts.

Great Product
I bought this for my Mountaineer and was afraid because of the price I was going to have problems with the installation or quality of the part.

Installation was easy. I didnt have any problems with fitting and the part was solid. I've been driving on it for about 2000 miles now with no issues. I would purchase again.

Very speedy delivery also, the company had the part shipped the same day.

Great Product! Direct Fit! Saved Hundreds!
Product Fit 2002 Ford Explorer 4X4! Wheel bearing and assembly looks great and felt solid! The online video was spot on and easy to follow!

From quotes I got from local mechanics and the big boys, I must have saved $400-500 easily. Two weeks no problems! Extremely happy. Need to do brakes next! Will use 1A auto again!!
