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.

Our control arms are designed to be direct replacements for the original factory parts.  They are 100% brand new and require no modifications for installation.  No special tools are required because all of the bushings come pre-installed.

Best Price & Warranty Available
Im not a mechanic so my opinion if from the consumer POV.t I purchased the control arms from 1A because they had the best price available. I received them I believe in a week from ordering the parts. 1A also offers a limited lifetime warranty unlike the competition.

Exact fit with great savings
When my upper control arms failed on my 1994 s10 I priced the bushings & ball joints and the price of having the bushing installed. I knew that there would be at least a one-day turn around at the machine shop so my truck would be down an extra day. I decided to search online and found this pair of control arms with everything I needed for less than $90. Cant beat this price and once in hand I easily finished the job in half a day. These are a perfect fit and a great value. Very happy with this purchase.

Whats the brand of this control arms?
Javier G July 18, 2017
Not sure. I have replaced a few like it on 4 or 5 different cars ex s10, camry, fusion and they are all syill running fine. Easier to fix with new bushings and joints at same time. I dont like working on it twice.

Do these come with alignment shims and are the ball joints treatable? Or greased?
Mike Q June 22, 2018
These parts will come just as pictures. It is necessary to reuse your original hardware, as new hardware is not included with this item. The ball joints will be pregreased and sealed.
Jessica D June 23, 2018
No alignment shims. There ball joints can be greased from the top side
Cory I June 26, 2018
Do they come with the bumper stops if not do you sell them and also do you price match with AM Auto Parts?
Private P November 2, 2018
Thank you for your inquiry! These do not come with the bump stops, and the only ones we carry are for the lower control arms. Unfortunately we do not offer price matching at this time.
