Diagram Ref No 8.
• Position on Vehicle: Rear axle, outer wheel hub/bearing carrier location (outer bearing set for the wheel assembly).
• Applications: Suitable replacement when the original wheel bearing shows wear, noise, play or when restoring classic 911 Turbo rear high-performance suspension/drive-train.
The outer rear wheel bearing is critical in supporting the wheel hub and bearing loads, particularly on driven rear axles like the Turbo's. When a bearing wears or deteriorate, you may experience wheel play, noise under load, excessive heat, or even catastrophic failure. Replacing bearing ensures correct tolerance, proper fitment and preserves wheel-hub stability and safety.
When and why to replace:
• Noticeable rear-wheel bearing noise, growl or whine under load or cornering.
• Detectable play in the rear wheel/hub when lifted and rocked.
• Over-temperature or rough feel at the hub after drives.
• During axle, bearing or wheel-hub overhaul, rear-driveshaft removal or major service.
• High-mileage vehicle or original bearing is suspected of nearing end-of-life.
