Changing propshaft

[lellyden]

Putting another propshaft on my Morris minor do I need to line this one up ,? Or just put it straight on ?

There wont be anything to line up to I'm afraid as any marks on the new prop would be for lining it up on the car it came off. Bolt it up and see how it goes, you can always turn it to another position if you find any slight vibration issues.
Good luck

Before you remove the old prop-shaft - mark the diff flange and prop-shaft rear flange adjacent to one another.
The reason for this marking is that the replacement prop-shaft may not be better balanced than the original prop-shaft and you may want to refit the original prop-shaft and with the markings you can reinstall in its original position.
If you are replacing the complete prop-shaft fit the replacement prop-shaft and mark the prop-shaft rear flange adjacent to the mark on the diff flange.
Run the car and see what the balance of the shaft is like. If ok leave as is. If not perfect turn through 180 degrees and see what the balance like.
If better leave as is.
If not the marks come in handy to determine the best position for best balance.
If all else fails the prop-shaft will need to be balanced by a specialist company.
Unless you strip the prop-shaft to its component parts there is no need to mark the other parts of the prop-shaft.
If the replacement prop-shaft is already marked make your own identifiable marks so as not to get confused.

Why are you changing the prop? Are the cross/yolks worn - or as suggested above - is balancing the issue ?
