Steering shaft lower bearing. Porsche 911 / 914  ❭  90005203100

Steering Shaft Bearing (In Lower Shaft Housing).

Restore smooth, accurately supported steering shaft operation with this OE Match Steering Shaft Bearing. Designed for compatible Porsche applications, this bearing is located within the lower steering shaft housing and supports the steering shaft as it rotates.

Fits:
Porsche 911 1965-89
Porsche 914 1970-76

Diagram Ref No 2

The steering system depends on the shaft remaining correctly located and able to rotate smoothly as steering input is transferred from the steering wheel toward the steering mechanism. The bearing supports the shaft, reduces friction and helps prevent excessive radial movement within the housing.

Over time, the bearing can wear through repeated steering movement, age, contamination, corrosion or deterioration of its internal rolling surfaces. A worn bearing may create play in the steering shaft, roughness when turning or unwanted noise from the steering column or lower shaft area.

This OE Match Steering Shaft Bearing provides a high-quality replacement for a worn, noisy, seized or damaged original bearing, helping restore smooth steering shaft movement and correct support.

What This Product Does:

• Supports the steering shaft within the lower shaft housing.
• Allows the steering shaft to rotate smoothly.
• Reduces friction between rotating and stationary steering components.
• Helps maintain correct steering shaft alignment.
• Controls unwanted radial movement or play in the shaft.
• Supports accurate transfer of steering input.
• Helps maintain a smooth and consistent steering feel.
• Reduces noise caused by a worn or rough bearing.
• Replaces a worn, damaged, corroded or seized bearing.
• Provides an OE-style replacement for compatible Porsche steering systems.  

Symptoms Of Wear Or Failure:

• Excessive play in the steering shaft.
• Steering wheel movement that does not immediately translate into steering response.
• Knocking or clicking from the steering column or shaft area.
• Grinding, scraping or rumbling noises when turning the steering wheel.
• Roughness or resistance through the steering wheel.
• Steering that feels notchy or inconsistent.
• Unwanted movement detected at the lower steering shaft.
• Vibration through the steering wheel.
• Bearing noise that changes as the steering wheel is turned.
• Visible corrosion or contamination around the bearing.
• Excessive bearing clearance discovered during steering-system inspection.
• A bearing that feels rough or seized when rotated manually.  

Why Replacement Matters:

• The steering shaft provides the mechanical connection that transfers driver input from the steering wheel to the vehicle's steering mechanism. Correct shaft support is therefore important for precise and predictable steering operation.
• As the lower shaft bearing wears, excessive clearance can allow the steering shaft to move within its housing. This may introduce unwanted play, noise or vibration and can reduce the precise feel expected through the steering wheel.
• A bearing that becomes rough or partially seized can create resistance as the steering wheel is turned. This may make steering feel inconsistent or notchy and can place additional loads on surrounding steering shaft components.
• Continued use of a severely worn bearing can accelerate deterioration of the shaft, housing or associated joints. Because steering components are safety-critical, excessive play, binding or abnormal steering behaviour should be investigated promptly.
• Replacing a deteriorated bearing with this OE Match Steering Shaft Bearing helps restore correct shaft support, smooth rotation and precise steering operation.
