Helped me save money
I came across 1aauto YouTube video in reference to the upper support arm and installation. I went to their website and found what I needed, ordered it, and received it within 3 days. A local company wanted to charge me $610 to replace the part. Thanks to 1aauto parts and video I was able to save me over $400.

Perfect Fit
Pleasingly surprised with both quality and price. Made quite a difference with the handling and ride. When it comes to buying part for your vehicle you can't beat A1 Auto. You will never be disappointed.

perfect fit
when I knew control arms were needed I watched the video several of them and decided it was something I could do.
I was surprised at how little they cost and thought about buying the package with the lower ball joints until I found I would need a press.
Before the parts arrived I sprayed the nuts etc. also after I removed the wheel I removed the complete fender well plastic.
removeing that made it a snap
Took it for an alignment and all they had to do was set toe..

2004 Ford Explorer upper control arms
Very happy with my order. From start to finish. Ordering was easy. Shipping was fast. Product fit perfectly. I previously ordered a set on eBay for $55 but when it arrived, the ball joint bolt was too thick and wouldn't fit. But the 1aauto set was just a delight! And I really enjoyed the YouTube video of the how-to tutorial how to install. Thanks

Do you get driver side and passenger side for 81.00 ?
Niggarich on Dec 24, 2016
BEST ANSWER: I don't remember exact cost but I did by the pair and they were excellent quality and I swapped both out even though passenger side didn't seem to need replacing. They are still holding up great. The video showing how to install is spot on
Do the upper ball joints come with the grease fittings?
Jeremiah on Apr 3, 2018
BEST ANSWER: These ball joints are sealed and pre-greased from factory. They are not serviceable.
