Moi,
muistan jostain lukeneeni että kardaanin palkeeseen laitettaisiin tilkka öljyä jotta paljevauriot paljastuisivat ennen suurempaa vahinkoa. Ei kyllä ihan vakuuttavalta kuulosta, mutta jos joku tunnistaa ohjeen niin kuitatkaa.
Onko perä ollut sulla aiemmin auki?

http://www.sterndrives.com/precisionparts/421.htmlLight rust on the u-joint shaft may not be a problem.
The main concern in using a rusted u-joint shaft is the aft Yoke.
The front main oil seal for the outdrive rides on a machined surface on the aft Yoke.
Water and rust pits this normally-smooth surface making it impossible for the seal
to hold oil in the outdrive. When this seal fails, drive lube will be forced out
the front of the drive and into the u-joint bellows. Lack of lube will then ruin the drive unit.
When you removed the drive from the bellhousing you may have seen oil in the bellows.
This indicates a very serious condition that must be tended to while the drive is off.
It doesn't take long for all the oil to be forced out that front drive seal.
This type of failure usually requires replacment of the main front drive seal
and the pitted worn Yoke shaft. Simply replacing the seal is not good enough.
Sometimes we may find oil in the bellows even when there is no rust on the shafts.
This can occure because the seal can wear a groove in the yoke surface.
This worn groove will then ruin the seal and oil will leak out of the drive.
Be careful. Pressure testing the drive may not reveal a worn, grovved yoke.
A grooved yoke might only leak when warm and at higher RPM's.
Some techs will install a Speedi-Sleeve on a worn yoke to save a little money.
We do not recommend installing Speedi-Sleeves for this application.
