In germany we have an after market supplier called Lemförder. He produces engine mounts for the 987 S which cost much less than Porsche OEM parts. Part number of the Lemförder motor mount is 34705 01. Porsche part numbers are: 98737502302, 98737502303, 98737502304, 98737505702. So at first sight it seems to be a 987 part and not compatible to a 986S. But if the parts qould be identical this would be a bargain.



Thanks and regards

Should be the same. I replaced my 1999 (non S) with a 987 mount. I don't know whether the 987 mount was from an s or not, or if they are even different.

If it has never been replaced you are likily due for replacement. The rubber gets old and cracks. Just replaced mine with 55k. For me the sympton was a sloppy shifter with 2 gear being sometime difficult to engage. After replacement it shifts like new.

Far as I know I'm still running on my original mount so will be something I look into in the spring. Can someone give me a rough estimate of what that repair would cost (part and labour)? I already have some projects on the todo list and unfortunately, I do have an annual budget to stay within. Thanks!

101 projects has this as very simple job requiring only a floor jack.
Under $200 for a new 987 mount and 2 hours of DIY time.

I did mine last summer. Two hours sounds about right. Not a hard job but it is tight to get at the bolts. I suggest using a mechanical jack under the engine so you can make small adjustments to get everything aligned. Also a set of ratcheting wrenches came in handy.

Thanks.

my mount has part number 986 375 023 05 (2003 Boxster S). So i did a little Google serach and found that the part number has changed from 986 375 023 05 to 987 375 023 05.

But i haven't found an aftermarket part made in germany right now. We will see.
