Steering Knuckle

Genuine OEM Steering Knuckles

The steering knuckle ties the wheel hub, suspension, and steering linkage together in one part, so any crack, wear, or bend shows up fast as a handling problem. Warning signs include uneven tire wear, a loose or wobbly wheel, clunking over bumps, or steering that pulls to one side. Because this part carries so much combined stress, a generic replacement can flex or fail where the original casting wouldn't, putting alignment and safety at risk. That's why every steering knuckle in this collection is genuine OEM, matched to the manufacturer's original part number.
