Grease is a thick, tacky lubricant designed to stay put in components that can't hold liquid oil — wheel bearings, ball joints, U-joints, and other chassis points that see constant friction and need protection that won't drip or fling off under load. Dried-out or missing grease is a leading cause of premature wear, noise, and eventual failure in these components, especially on parts with a grease fitting meant for regular service. Browse wheel bearing grease, chassis grease, and specialty greases for cars, trucks, and SUVs to keep high-friction components properly lubricated.
