• Position: Lower front suspension — between chassis and wheel hub (lower control arm)
• Function: Supports lateral and longitudinal loads, Maintains correct alignment geometry during suspension compression and rebound, Provides mount for lower ball joint and stabiliser linkage
Original arms can suffer from metal fatigue, corrosion, bent geometry from impact, or worn bushings, which lead to:
• Excessive play or looseness in steering
• Uneven tyre wear or misalignment
• Disturbed camber or toe under load
• Noisy suspension or clunking
Replace the control arm during full front-end overhauls, after collision damage, or when measurable play is detected in the ball joint or bushings. An OE Match arm restores correct suspension geometry, handling balance, and safety.

OE Match rear wishbone inner bushing, designed as a direct replacement suspension bushing for the rear lower control arm (wishbone) on selected Porsche 924S and Porsche 944 models.
Sold each. 2 required per vehicle.
Fits:
Porsche 924 1976 - 1985
Porsche 924S 1986 - 1988
Porsche 944 1982 - 1985
Diagram Ref No 11.
This product is an OE Match replacement inner rear wishbone bush that fits into the inner pivot of the rear lower control arm (wishbone) on classic Porsche sports cars.
The rear wishbone inner bushing allows the control arm to pivot smoothly relative to the chassis while absorbing road shock and vibration. It plays a major role in:
• Maintaining rear suspension geometry
• Damping vibration and noise
• Supporting lateral and longitudinal loads
• Providing stable wheel alignment under load.
Without a properly functioning bushing, the rear suspension can develop unwanted play, unpredictable handling, and accelerated tyre wear.
Function
• Pivot support: Allows controlled movement of the rear wishbone
• Vibration isolation: Reduces NVH (noise, vibration, harshness) transmitted into the chassis
• Load handling: Supports dynamic loads during acceleration, braking, and cornering
• Alignment stability: Helps maintain correct rear camber, toe, and overall suspension geometry.
A worn or degraded bushing can compromise the vehicle’s balance and rear road feel.
Rear suspension bushings sit at the center of dynamic wheel control. As these bushes age, the rubber compound can:
• Harden, crack, or split from heat aging
• Become loose or detached from the metal sleeve
• Allow excessive play in the suspension link
• Cause knocking or clunking noises
• Lead to uneven tyre wear and decreased handling precision.
Worn inner wishbone bushings compromise ride quality and chassis stability. Replacing them with OE Match quality bushings restores correct suspension articulation, improves handling feel, and keeps axle alignment consistent - which is essential for safe and confident driving.
When to replace. Replace the rear wishbone inner bushing when:
• You notice rear handling vagueness or looseness
• There are clunking noises from the rear suspension over bumps
• Tyre wear is uneven or irregular
• Rear wheel alignment cannot be held within spec
• You are performing a suspension overhaul

OEMatch Wishbones & Bushes — Control, Stability, Comfort
Wishbones and bushes are core suspension items that control wheel location, movement and alignment on Porsche models. OEMatch supplies direct-fit wishbones and alternative bushes selected for servicing, restoration and setup work, helping maintain intended steering behaviour, tyre contact and ride comfort across model generations.
- Standard replacement wishbones and control arms
- Rubber and polyurethane bush options
- Corrosion-resistant and strengthened control arm variants
Understanding OEMatch Wishbones & Bushes
OEM (Original Equipment Manufacturer) parts are made by the same company that produced your Porsche’s original wishbones & bushes.
OE (Original Equipment) refers to parts matching original specifications for the wishbones & bushes and may be supplied by alternative manufacturers. Aftermarket parts offer alternative options, sometimes with enhanced features or better value. OEMatch supplies non-OEM wishbones & bushes engineered as direct-fit alternatives to OEM parts, made to original-spec dimensions and tolerances for Porsche models.
Wishbones (control arms) locate the wheel hub and transmit suspension loads while bushes isolate vibration and allow controlled articulation. Correctly functioning bushes control camber, caster and toe under load and preserve intended steering response. OEMatch maintains a wide catalogue of Porsche items, documenting over 4,000 part numbers and more than 8,700 OE cross-references, and continues to develop new parts to support servicing and restoration.
Benefits Include
- Restores correct suspension geometry and wheel alignment
- Reduces vibration and unwanted noise transmitted to the chassis
- Improves steering precision and tyre wear consistency
Why Wishbones & Bushes Wear and Fail
- Bush rubber cracking, splitting or hardening due to age and environmental exposure
- Corrosion, bending or fatigue in wishbone arms and mounting points
- Impact damage from potholes or kerbs causing deformation or misalignment
The Importance of Replacing with OEMatch Wishbones & Bushes
Replacing worn wishbones and bushes restores predictable handling and preserves tyre contact patches on Porsche vehicles. Correct components protect other suspension items from accelerated wear, help maintain alignment settings used for safe steering response and support the intended balance between comfort and control.
Advantages
- Direct-fit alternatives made to original-spec dimensions and tolerances for straightforward replacement
- Choice of standard rubber or polyurethane bush compounds to suit comfort or performance preferences
- Parts manufactured from corrosion-resistant materials to reduce long-term maintenance
