Gusher Bearing design: a metal-to-metal Problem Solver bearing lets grease flow across the bearing surface to reduce friction and support long service life.
Greaseable socket: allows fresh lubricant to flush out contaminants, helping reduce corrosion and wear.
Heat-treated ball stud: treated to match or exceed OE requirements to resist premature failure and improve fatigue strength.
Belleville preload washer: helps keep the bearing package tight as the bearings wear.
Precision tolerances are intended to ease installation and steering alignment. Signs the original may need replacing include clunking, wandering steering, or uneven front tire wear. Replacing a worn front lower ball joint helps restore steering and handling feel. See the Buyer's Guide tab for the full engine-level application list.
