So about a week or two ago, whenever I make a right turn, I hear and feel about one or two thumps on the driver's side. I can feel it through the floor board.

Lifted up the car and didn't look like anything was loose and there was no play. Does anyone have a clue on what could be the issue?

 

It could be your axles going bad. Do you feel it on the steering wheel also?

 

Usually when axles go bad there's a constant clicking noise which I don't experience.
