Rear V shape wishbone Porsche 993 1994-97 (OE No. 99333104102 / 99333104202)

Rear V-shape wishbone (rear lower control arm) is the replacement for the Porsche 911 (993) rear axle. It locates the rear hub, controls toe/camber under load and carries the ball-joint and bushing interfaces that keep rear suspension geometry precise. Replace worn or damaged arms to eliminate play, restore crisp handling and correct abnormal tyre wear.

Why replace the wishbone?

• Worn bushings or a failing ball joint introduce free play — the car feels vague under braking/cornering and can develop a shimmy.
• Corrosion, impact damage or bending (kerb or track incidents) will change suspension geometry and lead to rapid/uneven tyre wear.
• Old arms allow unwanted deflection; replacing them restores factory kinematics and improves driver feedback, especially important on lowered or high-mile 993s.

Common issues / failure modes

• Ball-joint wear — ball joints loosen or develop play; when they go the arm must be replaced or re-balled.
• Bushings deteriorate — rubber bushings crack, get soft or collapse, allowing alignment drift and tyre cupping.
• Corrosion / fatigue — especially on UK/EU cars exposed to salt; can lead to seam rust or metal fatigue on older arms.
• Bent arm from impacts — an arm that’s been hit will change toe/camber and should be replaced, not straightened.
