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.

Leading evidence: 'Use should last another 1 million miles'' (no explicit attributable resolution; this is a reported action or suggestion). Across 1 matching discussions, The most frequently discussed action is 'Use should last another 1 million miles'' (1 discussions). For that action, 0 discussions report a resolution and 0 report an unsuccessful attempt. No action has an explicit, attributable resolution report under the current rules. These are forum reports and suggestions, not a confirmed diagnosis.
Source reports, not a diagnosis or a success probability. Counts refer to discussions and can overlap.
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.

Nope J/K
Apparently this was an LN bearing from a 2002 C4S who'd had the bearing replaced at 98,000kms (I'm in NZ), and it has just exploded 35000 kms later.
I thought all C4S will be on single-row? Also can we tell from the picture whether it's an LN bearing? The owner might have been duped by the shop thinking he'd paid for LN products.
Obviously the rest of the 'less-informed' starting to offer their opinions in the club's facebook page. Understandable as most of them are air-cooled worshipers. Hence I came here first to get feedback on what I'm looking at from the 'more-informed'.
It fooled you. Thats a single row, what appears to be a second row deep ball bearing groove is actually extreme wear from the bearing failure. This is where the ID of the shafts creates the damage.
I need to see the face of the flange to prove that its an LN unit.
Wow, thanks Jake. That would have been shedding metal (and ceramic?) materials like crazy then. Quite possibly the owner doesn't have magnetic plug.
The owner has been posting to the porsche club's fb page, I'll try to get him in here to talk about his experience. That was his picture replying to my questions.
I wondered. The dual groves definitely make it look like it, but the flange looked too thick above the seal. I didn't have mine handy to compare with though.
Having mine in hand now I see that the flange pictured is indeed thicker both above and below the seal. At least compared to my factory dual's flange.
This is a source reference. Confirm exact model applicability in the original material.
