Diagram Ref No 3

Manufactured from high-strength forged or cast alloy (depending on the original application), complete with premium-quality rubber bushes and a precision-engineered ball joint where applicable, the control arm is built to withstand heavy cornering forces, braking loads and everyday road conditions. Precision-manufactured for direct OE-style installation, it restores the factory suspension characteristics while ensuring long-lasting reliability.  

What This Product Does:
  • Locates and supports the front wheel hub assembly.
  • Maintains correct front suspension geometry.
  • Allows controlled suspension movement over uneven road surfaces.
  • Supports precise steering response and vehicle stability.
  • Helps ensure even tyre contact with the road.
  • Reduces vibration and unwanted suspension movement.
  • Restores factory ride quality and handling performance.
  • Forms an essential part of the front suspension system.

Symptoms Of Wear Or Failure:
  • Knocking or clunking noises from the front suspension.
  • Excessive steering play or vague handling.
  • Uneven or accelerated front tyre wear.
  • Steering wheel vibration.
  • Poor wheel alignment.
  • Vehicle pulling to one side.
  • Worn or split suspension bushes.
  • Excessive play in the integrated ball joint (where applicable).
  • Reduced braking stability.
  • MOT or vehicle inspection failure due to worn suspension components.

Why Replacement Matters:

  • The front lower control arm is subjected to continual loads from steering, braking, acceleration and suspension movement. Over time, the rubber bushes can deteriorate and the integrated ball joint can develop excessive play, reducing the suspension's ability to maintain correct wheel alignment and vehicle stability.
  • A worn control arm can lead to poor handling, increased tyre wear, steering vibration and reduced braking confidence. Continued operation with damaged suspension components may also accelerate wear of other steering and suspension parts, leading to more extensive and costly repairs.
  • Replacing a worn or damaged front lower control arm restores the original suspension geometry, improves steering precision and enhances ride comfort. The OE Match replacement provides factory-style fitment, premium-quality construction and long-lasting durability, helping maintain the responsive handling, safety and driving dynamics expected from your Porsche.

Over time, suspension bolts are exposed to significant stress, vibration, corrosion, and environmental factors. During any suspension service or component replacement, it's recommended to replace these critical fasteners to ensure proper clamping force and structural integrity. Using an original bolt ensures correct thread pitch, accurate dimensions, and manufacturer-approved material strength - critical for high-precision vehicles.

This bolt is used in many Porsche models, including the 911, 718 Boxster, and 718 Cayman, depending on the suspension configuration. Whether you're performing routine maintenance, replacing a control arm, or performing a steering repair, which is crucial for maintaining wheel alignment, installing the correct bolt helps maintain your vehicle's handling, safety, and long-term reliability.
