Good quality parts with a lifetime warranty at a fair and reasonable price. Quick and easy shipping arrived in 3 days. Parts went in quick and easy. No problems with the parts or shipping. Would recommend these to any one doing a job like this!

Always a great company and always a great product
December 8, 2019
I highly recommend 1a auto. I decided to try them out about 4 years ago. I was skeptical just because of the low prices. If it sounds too good it probably is right? Wrong. Since then I have bought all of my parts through them. My husband always swears he can find a better deal. Every time he has come back to me and said "nevermind. We'll just use 1a auto" The parts are always a perfect fit and great quality. The shipping is very quick. They have tons of videos to help you diy. You really cant go wrong with 1a. Love these guys! I cant comment on customer service because I have never needed. Always received the right part the first time and always fits like it should!

Customer Q&A
Ask a question to 1A Auto customers who purchased the product
should this be pressed in with the boot in place or without and install the boot after?
October 3, 2016
boot goes on after its pressed on
October 4, 2016
Boot fits over lip on upper control arm. To avoid damaging it, install it after pressing ball joint into control arm.
October 7, 2016
Keep the boots on there is no problem with boots interfering with the install if done correctly. the ball joints are some what all ready greased. removal of the boot would cause contamination to the grease that's all ready in the joints
January 29, 2018
