Question about Steering Wheel.

[Mamba240]

Hows it going fam. I just had a quick question about my steering wheel. I have a 96 240sx and whenever I go on the highway my steering wheel will tend to vibrate to an extent whenever it hits a small bump. Likewise after a while of driving when I turn the steering wheel left or right it will make a howling noise.

My question is it my tie rod on the steering wheel itself? I recently had a wheel alignment on the car. I dont know what else it could be. Any help would be appreciated, Im new here as well so please no hate. Thanks in advance.
