Front Suspension Wear and Replacement
On the Porsche 993, common failure points in the front suspension include the control arm bushings and ball joints. As these components wear, you may notice clunking over bumps, loose or vague steering, uneven tire wear, or steering wheel vibration. Because the front suspension system is highly interconnected, wear in one part often accelerates the deterioration of other components.
To address this, we’ve developed a complete wishbone control arm & ball joints kit designed to restore handling, performance, and safety. This kit includes new front control arms and ball joints, ensuring a comprehensive solution rather than piecemeal repairs.

Why Control Arms Matter
Control arms serve as a critical link between the suspension and the subframe. Their hinged design allows the suspension to articulate as the vehicle absorbs bumps or navigates turns. On vehicles with independent suspension, like the 993, multiple arms and connection points contribute to better ride comfort and stability.
As bushings and joints within a control arm wear out, the suspension can begin to feel loose or unstable. While some designs allow individual components to be serviced, many control arms require complete replacement to restore proper function.
Symptoms of Control Arm Failure
Signs that your control arms may need replacement include:
- Excessive play where the arms connect to the subframe or knuckle
- Clunking or knocking noises from the suspension
- Uneven tire wear
- Difficulty achieving proper wheel alignment
- Steering wheel vibration at highway speeds
- Wandering or pulling sensation through the steering wheel

This OE Match front wishbone ball joint is a direct replacement for the original Porsche suspension component fitted to Porsche 911 models produced and Porsche 914. It connects the front wishbone (control arm) to the wheel carrier, allowing controlled suspension articulation and accurate steering movement.
Sold individually, 2 required per vehicle
Early type with round cut out. Requires round pin. Not included with the ball joint.
Fits:
Porsche 911 08/1969 - 07/1971
Porsche 914 1970 - 1972
Diagram ref no 13
Installed at the outer end of the front lower wishbone/control arm, the ball joint forms a critical pivot point between the suspension arm and wheel hub carrier. It allows controlled articulation during steering and suspension travel while maintaining correct wheel alignment and suspension movement. Proper ball joint operation is essential for steering accuracy, chassis stability, and predictable handling.
This early-style ball joint features the correct configuration for early Porsche suspension systems and is suitable for restoration work, suspension refurbishment, or replacement of worn original components. Certain versions are supplied with lock plate and split pin hardware depending on application.
The front wishbone ball joint connects the lower control arm to the wheel carrier while allowing controlled steering and suspension movement. It supports stable handling, precise steering response, and proper front wheel alignment.
Function
• Connects front wishbone/control arm to wheel carrier
• Allows steering and suspension articulation
• Maintains correct front suspension geometry
• Supports precise steering response and stable handling
• Helps reduce suspension play and uneven tyre wear
Ball joints are subjected to constant suspension load, steering movement, and road vibration. Over time, internal wear can create excessive play within the joint, leading to vague steering, suspension knocking noises, unstable handling, and uneven tyre wear. Replacing worn ball joints restores safe suspension operation and factory steering precision.
When to replace
• Excessive steering play or vague handling
• Knocking or clunking noises from front suspension
• Uneven front tyre wear
• Failed suspension inspection or MOT
• Visible wear or looseness in suspension joint
• During front suspension rebuild or restoration

Ball joint lock pin is an suspension fastener designed to secure the front lower ball joint to the strut or wishbone assembly on classic Porsche models. It installs into the ball joint mount to secure the connection between suspension links and steering knuckles. It’s suitable for maintenance, rebuilds, or restoration of front suspension components and fits directly without modification.

The lock pin provides a secure fastening point that holds the front lower ball joint in place, ensuring the suspension components remain correctly aligned under load and motion. It helps transmit steering forces while keeping the joint assembly stable during driving.
Installed through the ball joint and suspension link interface, this pin maintains clamping and positional integrity, aiding the suspension’s ability to articulate smoothly while resisting unwanted movement. It works in conjunction with the control arm and steering knuckle to support safe, responsive handling.
Front suspension hardware like the ball joint lock pin can wear, corrode, or lose clamping strength over time, which may lead to play in the suspension, uneven tyre wear, and compromised steering feel. Replacing worn or damaged pins with OE Match parts helps maintain precise suspension geometry and consistent handling characteristics.
When to replace:
• Ball joint pin is corroded, bent, or worn
• Loose or sloppy front suspension feel
• During ball joint, control arm, or strut service
• Restoration of classic suspension systems
• After removal or disassembly of front suspension
