If you have never changed your lower steering column bearing that's located in the smuggler's box, there's a good chance that the bearing inside the rubber housing is non-existent. This bearing helps to prevent slop in the steering linkage assembly, but over time, the needle bearing inside gets corroded and ultimately disintegrates. This is often mis-diagnosed as a bad tie rod end because effect on the steering response is very similar. Rennline has created a billet aluminum housing the includes a pressed in needle bearing and unlike the factory unit, this one includes two weather seals to protect the bearing.
Replace it once and don't worry about it again.

Porsche UJs & Steering Shafts | Design911 Precision Components for Direct & Responsive Steering
Universal joints (UJs) and steering shafts form the vital mechanical link between your Porsche’s steering wheel and steering rack, allowing smooth and controlled transfer of driver input. These components ensure consistent steering precision by compensating for angle changes between the column and rack, maintaining a solid, vibration-free connection. A well-functioning UJ and shaft assembly is essential for maintaining Porsche’s renowned steering feel — precise, direct, and confidence-inspiring.
At Design911, we offer a wide range of steering UJs and shafts, designed for strength, durability, and exact fitment. Manufactured using high-grade steel and precision-machined joints, our components deliver exceptional performance under demanding driving conditions. Ideal for restorations, repairs, or performance upgrades, these parts help restore the precise steering response and feedback that define Porsche engineering excellence.
What Do Steering UJs & Shafts Do?
Steering UJs (universal joints) and intermediate shafts transmit rotational input from the steering wheel to the rack, allowing angular flexibility and precise steering control.
Core Functions:
• Transfer steering motion accurately from column to rack.
• Allow for steering angle changes and suspension movement.
• Reduce vibration and improve steering feel.
• Maintain alignment between steering components.
• Ensure safe, consistent steering response across conditions.
High-quality steering UJs and shafts are key to achieving Porsche’s signature handling precision and comfort.
Why Do Steering UJs & Shafts Fail or Degrade?
Over time, steering UJs and shafts are exposed to mechanical stress, vibration, and environmental elements that cause wear or corrosion.
Common Causes of Failure Include:
• Wear or play in UJ bearings leading to steering looseness.
• Corrosion from moisture or road salt.
• Seized or stiff joints from lack of lubrication.
• Cracks or deformation in the shaft due to stress or impact.
• Age-related fatigue in universal joints and splines.
When these parts fail, you may experience steering stiffness, vibration, or excessive play — all of which can compromise safety and control.
Why Replace or Upgrade Your Porsche UJs & Steering Shafts?
Replacing or upgrading worn UJs and shafts restores smooth steering operation and precision control. Enhanced materials and improved joint design also provide increased durability and feedback for high-performance driving.
Key Benefits:
• Restores direct, responsive steering feel.
• Eliminates vibration and steering play.
• Improves safety and control under all conditions.
• Corrosion- and wear-resistant construction for longevity.
• Compatible with Porsche 911, 944, 968, Boxster, Cayman, Cayenne, and Panamera
models.
• Ideal for restorations, servicing, or performance enhancements.
Design911’s Porsche steering UJs and shafts combine precision engineering and superior materials to deliver smooth, reliable steering response and driver confidence.
Highlights
• Premium Porsche UJs, intermediate shafts, and steering
components.
• Precision-machined for strength and smooth articulation.
• Resistant to corrosion, vibration, and impact stress.
• Direct-fit solutions for both classic and modern Porsche models.
• Enhances safety, control, and steering accuracy.
• Perfect for servicing, restorations, or performance tuning.
