My car shudders and sounds when driving fast or slow

I’ve got two questions about some things going on with my car.

The first issue I’m having is when I go around left curves on the highway upwards of 70 mph and faster my entire car shudders. Only when I’m going fast and making some what of a tighter curve though and only going left. Any ideas?
The second issue is randomly there is this steady sporadic clunking noise that comes from the passenger side foot area/glove box area (somewhere around ten clunks in a row) I can’t seem to figure out whats causing it. It happens randomly. Sometimes when idling, sometimes when driving fast, sometimes when driving slow. It just seems really random. What’d you think?
I appreciate any possible answers. Thank you.
