Hello,
No,you can just replace the u-joints but it is reccomended to replace
the splined shaft leading into the coupler. first you'll need to pull
things apart...but i would say at a minimum you'll be looking at 2
u-joints,all 3 bellows should be replaced as well. But you cant tell
untill you have it apart...you may even have a shot coupler. i would
grease the gimbal bearing "heavily" and take it for a ride to see if
the noise is as bad,maybe that will give you more of an idea what
your in for.

Hey all... I wish I could give back what I get from this group... Anyways,
I'm having another problem...a small one I hope... when I'm in gear (havn't
tried in reverse) and above 1000RPMs I hear a kind of a rattleing clanging
noise coming from the back end... my thoughts are U-Joints and Gimbal (as I
didn't replace them when I did the bellows') It seems to getting mildly
worse as I use the boat more... it's a 77 Mercruiser 140... If it turns out
to be the U-Joints, do I need to replace just the U-Joints or do I need to
replace the whole shaft?

Thanks a lot again!
