You want to check them for any play. Pull the drive and turn them up-down left-right etc. and turn them to see if there is any play in them. IF you have ANY play, replace them. Hell I would replace them anyways if there old, and you have the drive out.

I replaced mine when the drive was taken off the boat this fall.. If they are old just replace them. Mine looked all rusty plus I didn't know the previous owner history. I was gonna just use chevy auto u-joints but the grease zert is in the wrong location. So I bought a set of marine ones from our buddie at the marina, which have the grease zert in the right location, these also were a heavy duty u- joint in which the needle bearings were larger. At the same time I went through the whole top end off the alpha with bearings, seals and put a water pump assembly and seals in the lower..

Shifter in forward, loosen nuts at front of trim cylinders, remove nuts washers and rubbers at back end of trim cylinders, then 6 nuts/washers that hold drive on. You would need new gasket and "O" ring at face where drive came off. Check bellows (u-joint and shift)thoroughly for cracks/tears or stiffness and replace if required. Spin gimbal bearing (where front shaft of drive came from) and make sure it spins smooth and not loose. Take good flashlight and look through the gimbal bearing at the splines in the engine coupler to make sure they don't look like sharp teeth. If u-joints are ok be sure to grease. Make sure you grease input shaft before installing the drive.

Thanks for the info David, that's what I was looking for. Where is the cheapest place to order the o-rings and gaskets from? I think Westmarine stocks a bunch of drive parts. Who else should I call? Any places on the net that have good service and cheap parts?

Gasket set comes with "O"rings and is about $15.00 I think. West Marine, or any local boat store should carry that part you need. The bellows are a little more. Try http://www.boatfix.com
for parts at a reasonable price.
