Steering column support bushing - Nylon replacement for 91134702901 Porsche 911/912/930 1974-1989.

rennline

Does your 74-89 911/912/930 have the common slop, wiggle and/or rattle in the steering wheel? This is a common issue with these cars and is the result of a worn-out OE 91134702901 bearing liner. Rennline's new Steering Column Support Bushing installs in about 15 minutes and leaves you with a smooth/quite steering column. This is a big improvement over the factory replacement sleeve that takes hours to replace and is sure to fail again down the road.

About Steering Racks

Porsche Steering Racks | Design911 Precision Steering Assemblies for Control & Performance

The steering rack is the heart of your Porsche’s steering system — translating driver input from the steering wheel into precise directional movement of the wheels. It’s a critical component that ensures responsive handling, stability, and control under all driving conditions. Whether your Porsche uses a hydraulic, manual, or electric power steering setup, maintaining a smooth and accurate rack assembly is essential for both performance and safety.

At Design911, we supply a complete range of steering racks, including hydraulic, electric, and manual systems for both classic and modern models. Each unit is built to high engineering standards, providing exceptional steering feel, precision, and reliability. Perfect for routine servicing, performance restoration, or full rebuilds, our racks ensure your Porsche handles exactly as it was designed to — sharp, smooth, and predictable.

What Do Steering Racks Do?

The steering rack converts the rotational motion of the steering wheel into linear movement, controlling the vehicle’s front wheels for directional accuracy.

Core Functions:
• Transfer steering input into smooth, precise wheel movement.
• Work in conjunction with the power steering system for ease of control.
• Maintain correct wheel alignment and tracking.
• Provide balanced feedback and road feel.
• Ensure stability and steering accuracy at all speeds.

A properly functioning steering rack delivers confidence-inspiring handling — from high-speed motorway cruising to tight cornering on track.

Why Do Steering Racks Fail or Degrade?

Steering racks experience constant pressure, movement, and exposure to heat and contaminants, leading to gradual wear over time.

Common Causes of Failure Include:
• Seal wear leading to hydraulic fluid leaks.
• Corrosion or pitting on internal rack surfaces.
• Play or looseness in steering due to worn bushings or joints.
• Power steering fluid contamination causing internal damage.
• Age-related degradation in gaskets or mounts.

When steering racks begin to fail, symptoms include excessive play, vibration, fluid leaks, uneven steering effort, or knocking noises — all signs that replacement or refurbishment is required.

Why Replace or Upgrade Your Porsche Steering Rack?

Replacing or upgrading your steering rack restores handling precision, stability, and steering feedback. Modern or performance-oriented replacements offer improved durability and response for both road and motorsport use.
