- Customer 3: I purchased a used Porsche with an unknown maintenance history. I immediately had the IMS bearing inspected and replaced. The peace of mind I gained from knowing that I had addressed this potential problem was well worth the investment.
Effective Strategies for Preventing IMS Bearing Failure
- Regular Maintenance: Follow Porsche's recommended maintenance schedule to ensure the bearing is lubricated and inspected as needed.
- Preventive Inspection: Have the IMS bearing inspected by a qualified Porsche technician every 50,000 miles or 5 years.
- Upgrade: Consider upgrading to an aftermarket IMS bearing solution, such as the LN Engineering IMS Retrofit, which is designed to be more durable than the original component.
Common Mistakes to Avoid
- Ignoring Early Warning Signs: Dismissing metallic rattling noises or oil leaks can lead to catastrophic engine damage.
- Delaying Repairs: If an IMS bearing failure is suspected, it is crucial to have it repaired as soon as possible to minimize the risk of further damage.
- Choosing the Wrong Solution: Attempting to repair the IMS bearing yourself or using unproven aftermarket solutions can increase the likelihood of failure and void the vehicle's warranty.
