volvo dps drive questions, help with knocking

[66mstgfsbk]

i have a 1999 Volvo dps drive behind a 5.7gsi engine in a 1999 245 fourwinns sundowner. i have a knocking when at full turn at low, near ide, speeds. it also has a vibration sometimes feels like a bad bent prop, but it goes away when i go to neutral and back into gear. i think the knocking is a gimbal, does that sound right? also hoping the vibration is the gimbal also? the props are stainless f6's, they are not bent or chipped. if i have to replace the gimbal is it best to do u joints or are they long life usage.

the other issue that i have is when i go from in gear into neutral the drive feels like it is thumping trying to get out of gear, it thumps for about 5 seconds then stops, it only does that once in a while. i just bought the boat and it ran great for a few times out then this started happening. there is no holes in the bellows but its starting to crack. i had a shop service the drive and engine before i came home after i bought it, so i dont know if the fluid they used can cause the drive not to come out of gear fully.

how hard is it to pull these drives? i have the service manuals and am not afraid to do it just want to know what to expect. do i need any special tools, i have everything automotive. thanks for all the help

First, there is no such thing a a "Gimbal" on a boat, there is a gimbal ring, a gimbal housing, and a gimbal bearing. So I will assume you mean the gimbal bearing. That is probably not the problem. Most likely ujoints, but any drive will make some noise when turned hard against the stop.
Pull the drive and check the ujoints for loosness.
As far as the problem coming out of gear, what's your idle rpm?
