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 replacement.

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.

The boot design is terrible
The boot has the same diameter as the widest part of the ball joint. Therefore, you have to pull the boot off before pressing. So far so good, but good luck trying to get the boot back on without ripping it after pressing it on. I could not figure out how to put the boot on without tearing. Maybe you can.

Dont buy
This are complete trash had a hard time installing them and didnt fit right. The boots are not assembled and its almost impossible to get them on with out ripping the boots and grease coming out. Spend the money and buy good ones and not this. Ended up buying 4 new one somewhere else.

Customer Q&A
Ask a question to 1A Auto customers who purchased the product
Are these greaseable?
Scott D January 25, 2017
Some of the manufactures we use provide grease fittings to ensure that routine maintenance may be followed and fresh grease may be applied at your convenience. Other vendors we use seal the ball joints and do not require grease to be applied.
