I Just started hearing an intermittent knock from the left rear end. It’s at high and low speeds. Had new bumper installed this last week (was rear-ended). I’ve been driving the car for three days since the bumper was installed and I haven’t heard any noises. So I doubt it was due to the accident or bumper installation. Yesterday I had a windshield installed but that wouldn’t relate.
I have 97,400 miles on the car. .
Does anyone have experience with this sound?
Thank you!!

I just noticed one knock followed by silence. Five min later, another two knocks. That’s how weird it is.
Then a knock while almost at a full stop.
