I agree on the vibrations... it indicates to me that something rotating and spinning is out of balance, which, if ignored, could possibly become worse and cause additional damage.
I guess I've always held the notion to fix thing quickly after a symptom arises, or to pre-emptively fix an upcoming issue. This has always served me well.

Ordinarily you'd be absolutely right. It's just that so many people have reported input shaft bearing noise over the years, and nothing comes of it. The bearings hot noisy early on in their lives. They just stayed that way without any further deterioration or failures. It's like the design promotes a rapid wearing in, and once the bearing reaches a happy wear state, it stops and is just noisy.
So, the wanting to replace the input bearing just because of noise is kind of a lost cause.
The vibration is totally different. I'd inspect everything. Flex discs especially. The vibration is a separate and much more pressing issue. The vibration isn't normal or benign and THAT will break something eventually.
