Hi, I have a 1986 Volvo Penta AQ131A with a Volvo 275 outdrive. I suspect the gimble bearing is starting to go because the outdrive "shudders" during high speed turns. What are the symptoms of gimble bearing failure and what's involved in changing it? I've read on previous posts that some models required an engine pull. I'm hoping just the outdrive has to come off. Thanks in advance.
