  • Includes new ball joints and rear bushings

  • Only fit vehicles that use a torsion bar suspension, does not fit vehicles that use a coil spring suspension

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 lower 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.

Should You Purchase this Control Arm with Ball Joint? 

Does your truck or SUV need new control arms? This pair of front lower control arms will help you get your suspension back in working order.

Control arms can fail when their ball joints face wear or damage. The ball joints allow the wheel knuckle to move smoothly, but if the joint wears out it can make your steering feel loose or sloppy. The rubber boots that protect the joint can tear and let in moisture and dirt that wears out the joint. If that happens you might hear popping and creaking noises from your front-end. The arms themselves could also rust out or break in an accident, causing many of the same symptoms. To check your control arm ball joints, raise the front end up, and move the wheels by hand. Watch to see if there's play in the joint when you move the wheels. If you have a bent or broken control arm, or failing ball joints, you'll want to replace your control arm right away.

For something as important as a control arm, you want to make sure you get a high quality part. This pair of aftermarket control arms is built of high quality materials to the exact specifications of the originals that came on your vehicle, also known as OEMs. We guarantee these to fit for several models from 1995 to 2011, including Ford Rangers and Explorers, Mercury Mountaineers, and Mazda B-Series trucks with torsion spring suspensions. For more fit info, check the "Vehicle Fit" tab.

If one control arm breaks, the other may be close behind. It's a good idea to replace your control arms in pairs. It will also help keep your ride even. You can replace your own control arms in your driveway or garage. Check the "How-To & Tools" tab for a video that will show you how it's done. You'll have to start by raising and supporting the front end and removing the wheel. Then remove any suspension parts attached to the control arms. Then you can unbolt the control arm from the frame and the wheel knuckle. After that, just install the new control arm, put the suspension back together, and reinstall the wheel. You should always get a professional alignment after working on your steering and suspension.

Great Price Great Service
I ordered the parts plus a second order for the rest of the front end parts. its almost two month later and no problems. The prices are great and the service is excellent.

Worked just as advertised!
The parts fit perfectly and the video provided by 1A was very helpful. The only reason I didnt give this purchase 5 stars is because the grease fittings for the ball joints both faced the wheels when they were installed which will make future grease application a challenge due to space constraints. In fact, I had to purchase separate grease fittings with 90 degree bends in order to use a grease gun in the confined space.
