As I get my 55 on the road, I realize I've never ridden in a stock version so I have no reference for stock sounds of a 50-year old drivetrain.
My 55 has a gear-related whine induced by pressure/torque. It exists during acceleration and modulates up and down depending on throttle. The same occurs with deceleration. It's not horrific but it can range near annoying. It's not a grinding or binding sound, just a drivetrain droning sound.
I'm not sure whether to think this is normal or a function of something I did or didn't do properly when rebuilding the transfer case. I have a standard 3-speed case bolted with Advance Adapter components to my GM 4L60. I use standard 90W oil.
I appreciate your thoughts.
