What This Part Does / Functions
• Locates the front lower control arm correctly
• Allows controlled suspension movement
• Absorbs road shock and vibration
• Helps maintain front suspension geometry
• Supports steering stability and ride comfort
• Helps reduce knocking, looseness and harshness from the front suspension
• Provides correct OE Porsche fitment and rubber compliance
• Replaces a worn, split, perished or loose original bush.
Why Replace This Part?
Front lower arm bushes are exposed to road load, braking force, steering movement, suspension travel, heat, dirt and age-related rubber deterioration. Over time, the rubber can crack, split, soften or separate from the bonded sleeve. A worn bush can cause suspension play, knocking noises, vague steering, uneven tyre wear and poor alignment stability.
Replacing the bush with a Genuine Porsche OE front lower arm bush helps restore correct suspension control, factory ride quality and stable handling.
Common Symptoms of a Worn Front Lower Arm Bush
• Knocking or clunking from the front suspension
• Vibration or harshness through the chassis
• Wandering or vague steering feel
• Uneven front tyre wear
• Poor wheel alignment stability
• Excessive movement in the lower control arm
• Front suspension noise over bumps
• Failed MOT / roadworthiness inspection due to bush wear.
When to Replace This Part
• If the original bush is cracked, split, perished or separated
• If there is excessive play in the front lower control arm
• During front suspension overhaul or wishbone repair
• If suspension knocking is traced to the lower arm bush
• If wheel alignment cannot be held correctly
• After kerb, pothole or impact damage
• When replacing related front suspension arms or hardware
• When restoring the suspension with correct Genuine Porsche OE parts.
Where It Fits on the Car
This bush fits in the front lower control arm / wishbone assembly. It is used at the inner/lower mounting position of the front suspension arm, helping connect the control arm to the chassis / subframe mounting point.
Professional installation is recommended, as the old bush normally needs to be pressed out and the new bush pressed in correctly. A wheel alignment should be checked after suspension work.
