LN Solution, do it once and never worry about it again.

I understand that Porsche upgraded the IMS design mid year 2005 in the Boxsters. I have a 2005 Boxster S and am trying to confirm that I have the new style bearing. Can I do this check using my VIN somehow? Other tagging on the car that can help me?

Thanks!!

I would make the assumption that the bearing is replaceable. Regardless, you should have whatever shop you do the work at the bare minimum remove the grease seal off the original bearing if you end up having the larger, non-serviceable bearing:

This might be equally unpopular to the single row Pelican bearing option, but I like it, and have done it twice. You can relatively easily find a 5204 2RS bearing (3204 is also the same as 5204) for about $50, which is a double row bearing. The difference between that and what you pulled out is the extra width where the spring groove sits (you will not find one with the machined groove, but it is possible to find one with the same width without the machined groove). The Pelican kit will work with a 5204 2RS, with a slight modification to the inner race spacer.

Thanks for the info. I decided to just go with the IMS Solution afterall. While a pretty easy job, I don't want to be doing it again lol

This is really the way it should be, and to go further, I think there is a "generic" cylindrical option as well for about the same price. I went with one of the branded cylindrical bearings only because when I sell the car I think it would be difficult to explain to any degree of a buyer's satisfaction that the bearing is good to go even if it has no name. I could not and still have not found anyone claiming a failure of any of the cylindrical bearings.
I will add that the "Solution" is heavily discounted on ebay for over 30% off by the very manufacturer but under a different store name (type4store). They claim it is an "open box" or a "return" but I know someone who got a new sealed kit and got a deal on the tool rental from LN with no expensive prequalification, etc. Or, are they really selling "returns" that might be of a lessor quality. There are other ebay vendors selling at a discount too. Regardless, I wouldn't feel great about ever paying full price for "The Solution". Kinda sucks that vendors do this, but they do.

Any kits sold on eBay in our Type4Store account are units that for one reason or another that have been flagged as having a small cosmetic imperfection or blemish but are otherwise 100% functional and have no damage or issue with them that would affect their performance (as stated in the auctions). This could be as simple as an imperfection on the anodizing on the spin on oil filter adapter.

As far as the pricing, we try to price match as best we can the other eBay sellers that are reselling our kits to give people the option of saving a few dollars on a kit if they are ok with a blem and still be able to buy them from the source. However, we do not offer free tool rental with kits sold through eBay - that is reserved for customers purchasing through LN's retail site. We started doing this only after several people called with bad experiences with other eBay sellers selling damaged or previously sold (and even fitted) parts.

Hello,

Just became the new owner of a 996.1! Excited and loving every corner so far! I've read just about everything on the 996 good and bad and have come to a good opinion that this 911 is the sweet spot.
I know just about all the history of this vehicle, but this last line you spoke of with the replacement engine being different, can you elaborate at all on this? It's been quite sometime now since you stated this and was wonder if more is known? My 996.1 had an warranty OEM engine replacement from Porsche, so I am curious as what could be different about it.

Happy to be here and excited to possible see any of you at meets!

Depends on when the replacement was built. After 05 I think, the bigger 997 bearing. The only way to know for sure is to see it.

My 02 had a replacement engine in 2013 by Porsche with only 17k mikes on it. I bought it last year from second owner with 43k. For piece of mind I had the IMS checked, RMS replaced and clutch checked. My replacement engine was an 05 with captured Ims but all current Porsche upgrades. My Indy said no reported failures on my bearing and drive it! I will monitor oil and replace it more often.

What do you mean by "captured IMS"?

JBari

Late 05 engines to end of series had a different case from Porsche. To replace an IMS in these later engines the case has to be split. Who knows why they did this.

Charles Navarro

They knew they had a problem and changing the case casting wouldn't have been feasible, but redesigning the IMS was easily done. The larger 6305 non-serviceable bearing increased load capacity to match the original dual row bearing but had the added benefit of increasing surface speed for the ***** during operation. The increased surface speed reduces the lubrication requirements and also extends the life of the bearing.

I'm still don't know what you mean by "captured IMS", but I think I follow you now.

Porsche updated the intermediate shaft with the mk2 996 3.6L VarioCam engine. Along with that came the dreaded 6204 small single-row bearing which was the most failure-prone and was phased out in '05. Then, starting with the 2006 model 997, Porsche introduced another updated shaft with the most robust bearing - the 6305 large single row. From what we know, Porsche recognized the 6204 couldn't handle the load within this application and replaced it with the 6305 bearing.

Therefore, I'm assuming you mean the 6305 bearing because it can not be extracted like the original dual row nor the 6204 single row. Correct?

Pretty simple. Captured/enclosed in the case. aka not removable. Well unless you want to drill the case
