What This Product Does:
- Linking the two sides — It helps distribute load between the left and right lower control arms, improving how the rear axle reacts to cornering or uneven surfaces.
- Maintaining relative geometry — By coupling the motion of the trailing arms, it stabilizes toe and camber changes under load, improving predictability.
- Reducing compliance / slack — The bar and its bushings resist unwanted movement in the lower control arms, preventing them from moving independently in undesirable ways.
- Improving handling balance — Helps reduce unwanted rear-end movement, contributing to better rear grip and more consistent behavior over bumps or transitions.
- Clunking, knocking, or banging noises from the rear suspension over bumps or during load shifts
- Rear-end looseness or vagueness — the back of the car may feel less planted or predictable
- Uneven or accelerated tire wear on the rear, due to geometry variations
- Changes in alignment under load, especially during cornering or when the car is unsettled
- Loss of consistent rear grip, especially on transitions or during spirited driving
- Restores rear stability and predictability — with rigid, properly bushing-supported linkage, the rear behaves more reliably
- Eliminates noise & slack — worn linkage causes audible play; a fresh bar or good bushings cure that
- Preserves alignment / geometry under load — prevents misalignment changes mid-corner
- Improves overall handling feel — better feedback, confidence, and consistency
- Prolongs life of connected parts — less undue stress on arms, mounts, and bushings

Information
Rear trailing arm, Lower.
The Porsche Genuine OE Rear Lower Control Arms (Part Nos. 8R0505311F and 8R0505312F) are factory-engineered suspension components designed for the rear axle of the Porsche 95B Macan. Often referred to as rear lower control arms or trailing arms, these components connect the rear wheel carrier to the chassis and form an essential part of the vehicle’s independent rear suspension system.
Fits:
Porsche 95B.1 Macan 2014 - 2018
Porsche 95B.2 Macan 2019 - 2021
Porsche 95B.3 Macan 2022 >>
Diagram ref no 7
Each arm is supplied as a single genuine Porsche product (sold individually) and includes integrated suspension bushings to ensure proper articulation, durability, and vibration isolation.
• 8R0505311F – Rear lower control arm / trailing arm (Left side)
• 8R0505312F – Rear lower control arm / trailing arm (Right side)
The rear trailing arm functions as a pivoting link between the rear suspension subframe and the wheel hub assembly. It allows the rear wheels to move vertically over bumps while maintaining precise wheel alignment relative to the vehicle body.
By controlling suspension movement and absorbing loads from braking, acceleration, and cornering, the control arm contributes to stable handling, smooth ride quality, and consistent tyre contact with the road surface.
Functions & Technical Role
• Wheel positioning: Maintains correct rear wheel alignment and suspension geometry
• Suspension articulation: Allows controlled vertical movement of the wheel over uneven surfaces
• Load distribution: Transfers forces from braking, acceleration, and cornering to the chassis
• Integrated bushings: Reduce vibration and road noise while allowing smooth pivot movement
• OE-engineered durability: Manufactured to Porsche specifications for long service life and precise fitment
Over time, control arm bushings can wear due to road impacts, vibration, and continuous suspension movement. When worn, drivers may experience:
• Clunking noises from the rear suspension
• Uneven tyre wear
• Poor wheel alignment or vehicle pulling
• Reduced handling precision and ride comfort
Replacing worn arms with genuine Porsche OE control arms restores the correct suspension geometry and maintains the Macan’s original driving dynamics.

What This Product Does:
- Acts as the pivot point between the rear lower control arm and subframe
- Absorbs vibration and road shock for a smoother ride
- Maintains correct suspension geometry and alignment
- Helps control wheel movement under load (acceleration, braking, cornering)
- Reduces noise, harshness, and vibration transmitted to the cabin
Symptoms Of Worn Or Failed Rear Lower Control Arm Bushing:
Noise & Vibration
- Clunking, creaking, or knocking over bumps
- Vibration through the floor or rear of the vehicle
Handling & Stability Issues
- Wandering or unstable rear end
- Poor cornering response
- Braking pull or imbalance
Wear & Alignment Problems
- Uneven or accelerated tyre wear
- Difficulty holding a wheel alignment
- Rear end “floaty” feel at speed
Visual/Physical Signs
- Cracks, splits, or visible degradation of the rubber material
- Play or movement at the bushing when pushed/pulled
Why Replacement Matters:
- Worn bushings allow uncontrolled movement in the suspension, which degrades stability, steering feel, and driver confidence—especially in corners or sudden manoeuvres.
- Proper bushings help maintain wheel alignment under load, reducing uneven tyre wear and extending tyre life.
- New bushings absorb shock and vibration more effectively, reducing harshness and noise transmitted to the cabin.
- Controlling unwanted movement helps prevent premature wear of control arms, ball joints, and other suspension parts.
