Information
Four point gearbox bearing.
A four-point contact bearing inside the gearbox housing that supports the pinion / differential or output shaft, maintaining correct alignment and rotational support under load. It is a critical structural component of the transmission case on classic 911 / 914 gearboxes. Sold as a single bearing unit - replace as needed when rebuilding or servicing the gearbox, or when diagnosing shaft play or bearing wear.
Fits:
Porsche 911 1965 - 1971 Manual Gearbox cars
Porsche 911 1965 - 1983 Sportomatic Gearbox cars
Porsche 914 1970 - 1976 Manual and Sportomatic gearboxes
This bearing replaces the factory-installed unit (or previous equivalent bearing - OE part number 99905201600) and restores proper gearbox support for shafts that transmit torque and rotational forces - vital for gearbox longevity and reliable shifting.
Gearbox bearings wear out over time from torque loads, heat, and repeated cycles. A worn or damaged four-point bearing may lead to:
• Shaft misalignment or excessive play
• Increased gear noise, whining or rumbling
• Premature wear on shafts, gears, or synchros
• Gearbox instability or failure under load
Replacing with a correctly spec’d bearing restores shaft integrity, ensures smooth power transmission, and helps prevent costly internal damage - especially important on vintage 911 and 914 gearboxes where early detection can save major rebuilds.
You should consider replacing this bearing if:
• There is noticeable shaft play or wobble in the gearbox output or pinion shaft
• You hear whining, rumbling, or unusual noise from the gearbox under load
• The gearbox has high mileage or has seen hard use
• You are performing a gearbox rebuild, overhaul, or restoration
• Internal inspection reveals bearing wear, scoring, or heat damage
