Front end vibration up acceleration; 2000 Volvo S40


I drive a 2000 Volvo S40 with 105k miles on it. I’m noticing some vibration from the front end upon acceleration at higher speeds (above 50 or so). I can feel it in the pedals and steering wheel. Sometimes the vibration is more severe, especially accelerating up hill on a highway.

any suggestions. should I be worried for my safety?
