Read evidence and context

Explicit resolution reports before identified causes, performed actions and suggestions. Within each level, matching component labels precede direct query mentions and inherited thread context; successful versus unsuccessful discussion counts, owner confirmations and independent discussion support determine order. This is not a probability of success.

Discussions that performed work without a confirmed outcome: 1

0 original-poster resolution reports. Counts can overlap; they are not unique people or a success rate.

0 discussions have direct query context; 0 report a fix in that context. Other evidence may inherit the discussion’s subject.

Performed · outcome unconfirmed
We have seen a well maintained Boxster have a catastrophic IMS bearing failure with under 40,000 miles and have changed a bearing in a 996 with over 100,000 miles that was still in good condition.

Coverage and how to read this overview

Counts describe captured discussions, not unique people or a diagnosis. Author identities are not reliably stored. Exact duplicate evidence is counted once across matching discussions; one discussion counts at most once per action/state. Multiple repairs reported together remain a combination. Suggestions and failed attempts do not establish a fix. Matches cover whole discussions and can include related faults, model variants and incomplete threads.

1 eligible posts · 0 unverified posts · 1 discussions match the subject in their title or opening post.

POST 1Original post

Porsche intermediate shaft bearing failures are one of the most talked about issues with the 996 and 986's with the M96 engine. During the design and product selection process, Porsche chose to save a bit of money by selecting a less expensive bearing that was "good enough". Time has proven, however, that the bearing selected was simply not up to the task and the resulting failures have cost owners huge sums of money. So it never surprises us when we have customers who want to skip the worry about IMS bearing failures altogether and replace it as soon as possible. Such was the case with this 996. Parts Installed: Porsche Boxster and 911 models LN Engineering IMS Retrofit -Single Row The Build Drive shaft removed Crankshaft locked into place Transmission removed exposing clutch pressure plate Clutch disk and pressure plate removed exposing worn out flywheel Flywheel removed exposing IMS bearing and rear main seal Camshafts locked into place Timing chain tensioner removed and hole plugged New IMS bearing, main seal, and engine case bolts New cam cap seals New IMS bearing, main seal, and engine case bolts Old bearing IMS Bearing removed Rear main seal removed Rear main seal and engine case bolts installed IMS Bearing installed New flywheel and clutch kit New flywheel installed New clutch disk and pressure plate installed Transmission bell housing cleaned out Transmission reinstalled Drive shaft reinstalled C/V shafts reinstalled Under body panels reinstalled The trickiest part about IMS bearing failures is how random they can be. We have seen a well maintained Boxster have a catastrophic IMS bearing failure with under 40,000 miles and have changed a bearing in a 996 with over 100,000 miles that was still in good condition. But when talking about a part that can cause thousands in damage if it does fail, security becomes incredibly important. This 996 decided to completely eliminate that concern and now, instead of spending his time worrying, can spend more time thinking about how awesome his Porsche is.
