I replaced the bearing in my '02 at 101k miles because I was in there doing a new clutch anyway, but the original bearing was still good as new.

I had the clutch and RMS replaced 2500 miles ago - the clutch went to clutch heaven, so I did the RMS thing at the same time.

At 200K, I replaced the double row because the engine was already out.

Get this though...the replacement was done in 2005 and I got the first of the new style engines with the bigger bearing which can not be replaced from the outside.

Me personally - I have 203K kilometres on my car, but the engine was replaced at 70K kilometres for reasons unknown (I actually think it was for some reason other than the IMS).
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.

As the owner of a 2002 Carrera w/64k that hasn't been upgraded yet, I'm curious if I'm being reckless not having the clutch, IMS and RMS done yet or what I read is internet hysteria. My Porsche mechanic says my bearing is silent and it will give you some warning because it starts making noise. They quoted me $2100 for the clutch, IMS and RMS by the way.
45,000 miles here on an 03 C2. I had the clutch and RMS replaced 2500 miles ago - the clutch went to clutch heaven, so I did the RMS thing at the same time.
Now I'm wondering if I should go for the 'latest" IMS replacement/upgrade/fix. My indy called to say there is now an "oil bathed" unit. That sounds better than the ceramic fix to me, and he is now suggesting I step up and do the fix. Cost was quoted at "about $2k"
Maybe he'll throw in an oil change, too
SR cars? Those are called Unicorns sir, and they do not exist.
I dont think hes referring to "the solution" as I think its more than $2000 installed. It sounds more like hes referring to my ingenious sealess oil bathed bearing which is much less than $2000. PM me if your interested in the much less expensive "common sense solution".
The marketing hype and self promotion here by some is shameless so be careful!
131K and climbing
When we did the clutch at 107K, the mechanic said that everything looked good and if the IMS hasn't gone bad at this point, it is probably not going to go bad
. I took his word and now 24K miles later she is running just fine
1999 C2 with 114,000 miles, original IMS bearing.
1999 Boxster with 126,000 miles on original IMS bearing.
1997 Boxster with 204,000 miles engine failed. Got more than my money's worth. Don't know what broke, don't care.
My C4S has 95K miles, previous owner only did RMS, no IMSB with clutch change. KK is misleading you (not the first time) here is the oil fed no-bearing solution:

You are a hypocrite.
I had the original until 101k miles on my 01. While doing the RMS I decided to do the upgrade since they were already in there and was only charged for the part not labor. I think the $550 for the upgraded bearing was worth it just for peace of mind and may help in resale.. kind of a cool paper weight as well.
01 C2 Cab, 80k miles and 99 C2 Coupe with 126k miles as well as three Boxsters with mileage from 65k on up. All on original IMSB. Although I do have problems sleeping at night.
125k, original single row, mobil1 used all it's life, original motor, flange and RMS only updated to the newer version with improved seals. I sleep just fine. 1k+ mile trips, no problemo.
'99 C2 w/ 76k miles - engine never dropped
'99 Boxster w/ 112k miles - original IMS bearing
I picked up the C2 three years ago with just over 30k miles on the clock and have had ZERO maintenance issues, so much for the garage queen theory! I personally would set these cars on fire before I would install any aftermarket monkey parts into them.
01 C4 at 70k with the original IMSB. RMS was replaced twice early in life but has been sound for the last 10 years. Clutch was also replaced at the same time the second RMS was done (had about 50% life in it, but I just had to pay for the parts and labor was covered).
I'm don't have sleepless nights over it, but I'll do the upgrade when I replace the clutch in the next 5-10k (which over course means it will let go on the way to the shop
).
99 C2 cab, 6 spd, 125,500 miles, daily driver, very well maintained (people run up to me and ask if it is new!). Original clutch, IMSB, RMS. No leaks, no nightmares...love my car.
This.
An actual failed bearing is rare, especially on cars with over ~50k miles. If it was going to happen, it would have happened by now (of course, there are exceptions, but they are even more rare).
I replaced the bearing in my '02 at 101k miles because I was in there doing a new clutch anyway, but the original bearing was still good as new.
Darrick, I think its because all of the SR's seals fail and most allow motor oil in (and out) enough to allow the bearing to survive. Its the ones where the seals fail but prevent enough oil flow, that meet with disaster. Who knows at what mileage this occurs? Mine at 57K had failed but bearing survived because of oil flow through it (obvious upon inspection).
I think you would have to be nuts not to change it while doing clutch. I think if your honest with a potential buyer, this will be a positive not a negative selling point for your car.
and Mike, I said SR not DR cars. Jeez, this turned into another poll?
Exactly. Drive your car and maintain it or sell the damn thing or at least suffer in silence over not knowing what you should do. No more posts from people looking for us to reaffirm their decisions for or against replacement.
Say what you will about the IMS problem not being real or about people with vested interests hyping up a failure that is unlikely to occur but that IMSsolution oil fed plain bearing that Jake et al developed looks pretty slick and elegant.
Me personally - I have 203K kilometres on my car, but the engine was replaced at 70K kilometres for reasons unknown (I actually think it was for some reason other than the IMS).
Get this though...the replacement was done in 2005 and I got the first of the new style engines with the bigger bearing which can not be replaced from the outside. So that 133K kilometres (that's 82K miles) on a big bearing motor and it's going as far as it's going.
I replaced the clutch last year and it was bone dry around both the IMS flange and the RMS so I left it alone.
I sleep fine by the way. These are fantastic cars.
