Rear wheel bearings are subjected to constant radial and axial loads, as well as exposure to heat, moisture, and road contaminants. Over time, normal wear, contamination, or loss of lubrication can cause bearing deterioration, resulting in increased noise, vibration, and wheel movement. Replacing a worn wheel bearing restores smooth wheel operation, improves vehicle stability, and helps prevent damage to the hub and suspension components. This OE Match component is an excellent choice for Porsche maintenance, repairs, and restoration projects.

What This Product Does:

Supports the rear wheel hub and axle assembly.
Allows smooth, low-friction wheel rotation.
Maintains accurate wheel alignment and stability.
Reduces rolling resistance for efficient drivetrain operation.
Handles radial and axial loads during driving and cornering.
Replaces worn, noisy, or damaged rear wheel bearings.
Provides an OE-style fit for straightforward installation.

Symptoms Of Wear Or Failure:

Humming, rumbling, or grinding noise from the rear wheel.
Excessive play in the rear wheel or hub.
Vibration increasing with vehicle speed.
Uneven rear tyre wear.
Roughness when rotating the wheel by hand.
Heat build-up around the wheel hub.
Bearing damage identified during brake or suspension servicing.

Why Replacement Matters:

The rear wheel bearing is a critical component that supports the wheel hub while ensuring smooth and precise wheel rotation. As the bearing wears, friction increases and internal clearances develop, leading to noise, vibration, reduced handling precision, and additional stress on the hub, brakes, and suspension. If left unattended, a severely worn bearing can affect wheel alignment and compromise vehicle safety.
Replacing a worn rear wheel bearing restores smooth wheel operation, improves handling stability, reduces unwanted noise, and helps protect the surrounding drivetrain and suspension components from premature wear. Manufactured as a direct replacement and produced to OE-style specifications, this OE Match Rear Wheel Bearing provides reliable fit, performance, and durability for Porsche maintenance, repairs, and restoration projects.

Steering shaft lower bearing. Porsche 911 / 914

90005203100/1

Product Information

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.
