Fits To Diagram Ref No 14

The bushings provide the flexible mounting points between the front control arms and the vehicle chassis. Their rubber construction allows the suspension arms to move through their normal operating range while absorbing vibration and controlling unwanted fore-and-aft or lateral movement.

Unlike harder polyurethane, solid or competition-style bushings, these standard rubber bushings are intended to retain a factory-style balance of ride comfort, noise isolation and suspension compliance.

They are particularly suitable for road cars, restorations and vehicles where maintaining original Porsche suspension characteristics is preferred.

What This Product Does:
The front control arms locate the front wheels and help maintain the suspension geometry as the wheels move over bumps, during cornering and under braking.

The control arm bushings sit between the arms and their chassis mounting points.

Their functions include:

• Supporting the front lower control arms
• Allowing controlled suspension movement
• Absorbing road shock and vibration
• Reducing noise and harshness transmitted into the chassis
• Controlling unwanted movement of the A-arms
• Helping maintain stable wheel alignment
• Supporting predictable steering response
• Maintaining front suspension geometry under braking and cornering
• Providing a compliant pivot point for suspension movement

Healthy bushings allow the control arms to move in the intended direction while resisting movement that could disturb wheel alignment.

Symptoms Of Wear Or Failure:
Common symptoms of worn front control arm bushings include:

• Clunking or knocking from the front suspension
• Noise when driving over bumps
• Knocking during braking or acceleration
• Vague or imprecise steering
• Vehicle wandering on the road
• Reduced straight-line stability
• Steering requiring frequent correction
• Front-end movement under braking
• Steering-wheel vibration or shimmy
• Uneven front tyre wear
• Changes in wheel alignment
• Reduced steering precision
• Front suspension feeling loose
• Visible cracking in the rubber
• Rubber separating from its mounting surface
• Bushings becoming hard or distorted
• Control arm visibly moving excessively within its mount

Because several suspension components can create similar symptoms, the complete front suspension should be inspected before replacement.

Why Replacement Matters:
Worn control arm bushings allow the suspension arms to move more than intended.

This can alter wheel position dynamically as the vehicle is driven.

Excessive control-arm movement may contribute to:

• Unstable steering
• Poor wheel alignment
• Uneven tyre wear
• Reduced braking stability
• Less predictable handling
• Increased suspension noise
• Additional stress on surrounding suspension components

Replacing deteriorated bushings restores controlled suspension-arm movement and helps return the vehicle to its intended steering and handling characteristics.
