The upper wishbone (also called an upper control arm) is a key component of the front suspension system. It links the chassis to the wheel knuckle and helps guide the motion of the front wheels as the suspension travels over road surfaces.

The upper wishbone stabilises the wheel hub and maintains correct wheel camber, caster and track during driving. It works together with the lower wishbone, ball joint and strut assembly to control wheel movement, absorb road forces and ensure stable steering response.
Replacing worn or bent wishbones with an OE Match arm helps:
• Maintain correct suspension geometry
• Improve steering precision and handling
• Reduce uneven tyre wear
• Restore ride comfort and wheel alignment
Function
• Wheel Guidance: Supports and guides front wheel movement throughout suspension travel
• Geometry Control: Maintains alignment angles (camber, caster) for predictable handling
• Load Bearing: Transfers vertical and lateral loads from the wheel to the chassis
• Durability: Reinforced design ensures long-lasting performance under dynamic driving conditions
Over time, the upper wishbone can deteriorate due to road impacts, pothole damage, corrosion, and natural wear of its bushings and joints. As it weakens, you may experience poor steering response, uneven tyre wear, pulling under braking, or vibration and instability at higher speeds. Replacing it with this OE Match upper wishbone restores proper suspension geometry, improves handling precision, enhances safety, and helps extend the life of tyres and related components.
Replace the upper wishbone if you notice:
• Unusual tyre wear patterns
• Clunking or knocking noises over bumps
• Steering misalignment or pull to one side
• Loose or imprecise steering feel
• During front suspension overhaul or alignment work

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.
