Rhythmic vibration?
Have a very odd rhythmic vibration in my C5. It's only really noticeable at 45+ (going to do further testing to see if it also only does it in 5th and 6th, or if it does it in 4th) and the rate of the vibration increases with speed.
The vibration isn't constant, it starts and stops evenly based on speed. Feels similar to driving on a rumble strip (although much milder in terms of vibration intensity).
I did remove the weight on the drivers side of the diff. Is it possible that that's what's causing this?

It's been a minute since I really drove the car, but going back to a post I made after driving it 2300 miles it was definitely there prior to me removing the damper, so that definitely can't be it.

While I have no idea what an LLM is, I am capable of using Google myself. That being said, I would have no qualms about anyone posting their own ideas or knowledge (especially if they have experience with this issue) especially since, as you said, there are many possible causes.

It is the same car, and it was a collision/salvage car. I've got a thread detailing the restoration (and the damage) here: https://www.corvetteforum.com/forums...n-project.html

So I had the rear tires rebalanced. Tech said that they were off by a little bit, but not much. Looks like it was the same weights, just shifted about 1/2" or so on the rim.
Vibration is still there, though less noticeable. Won't have time to really work on it for a month or two (wife's car needs a transmission rebuild) but I'll look at the wheel bearings next.
