Look....if you've gone this far you should change/replace everything you can now while the drive is off and apart. Gimbal bearing, bellows, shift cable, etc. as well as other parts, are all wear items. Unless you enjoy doing this job over and over. Remember....there is never time, or money, to do it right but always time, and money, to do it over.
Never has that axiom been truer than when working on a boat.
