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.

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. Can't 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.

Do these come with alignment shims and are the ball joints treatable? Or greased?
Tortilla on Jun 22, 2018
BEST ANSWER: 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.
Does this come with the two bolts and spacers that attach this to the frame and does this come with a grease fitting?
Chris on Jun 24, 2016
BEST ANSWER: No it's doesn't come with the two bolts or shims . You need to use your olds or you can get the bolts from the hardware store or the dealer . As far as the shims they have some at the auto stores or when you get an alienment .
Is the inner shaft included?
Squig on Jul 24, 2017

Javier G on Jul 17, 2017
BEST ANSWER: 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.
