  • Direct replacements
  • Built to strict quality control standards

Note: These are redesigned ball joints and may look slightly different from the originals, although they will install and function correctly.

Worn ball joints 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 loose or worn ball joints with our quality replacements.

One way to diagnose a loose, or warn ball joint, 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 for play, if it is moving you probably need to replace it.

Our steering and suspension components are pre-greased and sealed for long life and do not require the extra maintenance typically required by greasable versions.

Good parts, but not as described in the video
The parts that were used in the video were different and the boot came off to make it easier to press the joint in, but this part wouldnt allow the boot to come off. I wish the part had a way to fill the it with grease too. Overall it was pretty disappointing

Will this fit my car? Add a vehicle to make sure
Customer Q&A
Ask a question to 1A Auto customers who purchased the product
Do I have to buy upper ball joints for explorer if I already bought the lower ones for both sides?
Teresa W July 5, 2016
You do not have to replace uppers if they are not wore out, but I replaced mine because you have to have front end lined up by a shop anyway. So why do all at one time. Thanks, Leon
Leon C July 5, 2016
I would only replace them as a set uppers and lowers.
Bruce B July 6, 2016
Hey Teresa, I end up buying the upper and the lower ball joint for my F-150, make sure that you dont need the upper before you buy the lower, because if you need them both you probably get a better deal with buying them together. good luck!
Linda H July 7, 2016
