What This Product Does
This gearbox bearing supports the rotating pinion shaft and helps maintain its position within the transmission. Correct bearing condition is important for shaft alignment and controlled rotation under load.
Functions
- Supports pinion shaft rotation.
- Helps keep the shaft correctly located.
- Limits friction at the bearing interface.
Symptoms of Fault
Possible signs include speed-related whining, rumbling, excessive shaft movement or metallic debris in gearbox oil. These symptoms require diagnosis: clutch, linkage, mounts and lubrication faults can produce similar complaints.
Why Replacement Matters
Renewing a worn bearing helps address unwanted shaft movement and rough rotation during transmission repairs. Inspect neighbouring bearings, gears, seals and retaining components during dismantling rather than assuming this bearing alone explains every symptom.
FAQs
Can just one bearing be renewed?
It may be appropriate after inspection, but the condition of the remaining transmission components should guide the repair.
Does gearbox oil specification matter?
Yes. Use the lubricant specified for the particular transmission; changing oil does not repair mechanical bearing damage.
How should compatibility be checked?
Compare reference 99730229300, the vehicle details and the gearbox code before selecting the bearing.

Deep-groove ball bearing for dual mass flywheel. Size: 15 x 35 x 11.
OE Match flywheel support bearing for selected Porsche 996 and 997.1 Carrera models. This deep-groove component measures 15 x 35 x 11 and is intended for the dual-mass flywheel application.
Fits
Porsche 996 C2 / C4 1998 - 2005
Porsche 996 C4S 2001 - 2005

What This Product Does
This bearing provides rotational support within the specified flywheel application. It is an individual replacement component, rather than a complete flywheel or clutch assembly.
Technical Details
- Brand: OE Match.
- Construction type: deep-groove ball bearing.
- Dimensions: 15 x 35 x 11.
- Part references: 99905221000 and 99905221001.
- 996 diagram applications: Carrera 2/4/4S, M96.01/02/03/04, 1998–05.
- 997.1 diagram applications: M96.05 3.6L Coupé/Cabriolet and M97.01 3.8L Cabriolet S/Coupé S, 2005–08.
Symptoms of Fault
Drivetrain noise, vibration, pull-away judder or difficulty engaging gears can prompt inspection of the clutch and flywheel assembly. These symptoms do not establish that this bearing has failed; mounts, linkage and other worn components can produce similar complaints.
Why Replacement Matters
Renewal is appropriate when inspection identifies bearing wear or damage. During clutch or flywheel work, assess the surrounding components as well: replacing this bearing alone will not correct a worn dual-mass flywheel. Match the dimensions, vehicle application and original reference before installation.
FAQs
Does flywheel noise always mean this bearing needs replacing?
No. Diagnose the assembly first, because clutch wear, flywheel play and mounting faults can cause related symptoms.
What should I check before choosing this part?
Confirm the model, production date, engine and transmission specification, then compare the bearing dimensions and part references with the component being removed.
