^^ Heh, I had a LUV too (27 years ago) and the clunk sound this car makes is very similar to what that little truck did. It's not a U joint failing but I'm pretty sure it's everything catching up and "landing" as the shaft and rear end are spinning at different rates. Did that make sense? If you go under the car when it's on a lift and either spin a rear wheel or the driveshaft you'll hear and feel the clunk. I've had a few vehicles that make a similar noise and decided a long time ago not to worry about it.
You've been driving stick for 26 years? Newb
