2007 Porsche 911 Carrera S

Short answer: For a 2007 911 Carrera S, you don’t need to worry, but you should be aware. Your ‘07 has the upgraded IMS bearing design that Porsche introduced in 2006, which is significantly more reliable than the earlier version.

The details:

Your 2007 997.1 Carrera S has the larger, upgraded single-row IMS bearing that Porsche introduced for the 2006-2008 model years. This replaced the problematic smaller single-row bearing used from 2000-2005 that had the infamous ~8% failure rate. The larger bearing in your car has a dramatically lower ~1% failure rate and much better load capacity.

What this means for your situation at 44k miles:

• Risk level: Low — You’re past the typical early-failure window, and the improved bearing design is holding up well at this mileage
• No urgent action needed — Unlike early 997.1 or 996 cars where preventive replacement was almost mandatory, your car doesn’t require preventive IMS bearing replacement
• Inspection opportunity — The bearing is technically “non-serviceable” (sealed), but when you eventually replace the clutch, a Porsche specialist can remove the transmission and inspect the bearing by popping off the grease seal to check for wear

Bottom line: Drive it and enjoy it! The IMS bearing on your ‘07 Carrera S is not the time bomb it was on earlier cars. Keep up with regular maintenance, use quality oil, and don’t lose sleep over it. If you ever have the clutch done, that’s your chance to have it inspected.
