shifting trouble

My problem yesterday may assist you.

For about a week I noticed a little vibration in the seat, when I was 'first' taking off. It lasted only a moment, then was gone. Not in reverse.

I finally had some time, so I put it on the rack at work. I saw the center support bearing was sagging in the rubber donut. I tries prying one way then the other on each of the u-joints to see if I could see any play in them. (I've done many customers u-joints over the years).
Nothing. Everything 'looked' tight.

So...I removed the driveshaft. When I tried to move the u-joints around, all 3 had 'stiff' spots in them.
(factory joints seldom have grease fittings, so they had never been greased).

I took it over to the driveshaft shop (as I am way too busy to do them) and had all 3 joints replaced, and the support bearing, and balance the whole setup.
My cost was $197. retail is $300.

And I put a new output shaft seal in while the shaft was out. $8.
