This is a pair (left and right) of brand new front lower ball joints for specific Toyota Corolla and Geo Prizm models from 1993-1995. (Double-check your exact year, trim, and that it's a FWD model). Ball joints are a critical part of your front suspension – they connect your steering knuckle to the control arm and allow for movement. When they wear out, you might notice loose or shaky steering, strange squeaks or clunks from the front end, uneven tire wear, or your car pulling to one side. These replacements are made from steel, come pre-greased, and include any necessary nuts or bolts as shown. They have a 1-year warranty. Replacing worn ball joints is important for safety and proper alignment. Have a mechanic install them if you're not comfortable doing suspension work yourself.
