Worn ball joints or loose rear bushings can cause excessive front tire wear, popping or creaking in the front end, extra play in the steering system, and pose a serious safety concern. Replace that heavily rusted, rotted, or damaged front upper control arm with the loose bushings or worn ball joints with our high quality all in one replacement.

One way to diagnose a loose, or warn ball joint on a control arm, is to jack the car up, so the wheel is off of the ground, then have someone try to move the wheel in and out. While they are moving the wheel check the ball joint and bushings for play, if it is moving you probably need to replace it.

Perfect fit
Ordered these parts because my truck hadn't been properly taken care of before I bought it. They fit perfectly, were easy to install (I watched the videos they provided) and I don't have to worry about greasing them later on. Getting my old parts off was a different story. I will definitely be getting my parts from 1A Auto from now on!!

Upper control arms order
I had ordered a set of upper control arms for my F-150 . This company not only sold the control arms but the bushings and upper ball joint was already in there. They had beat all there competition. For researched all the different sites and found an original equipment parts for an excellent price. And the install I performed myself. was easy . Later that day I had informed all of my friends that build and customize there 4 wheel drives about your prices and outstanding service. Thanks for the good experience. Rico
