1995 Subaru Impreza Shake and alignment Issue

Gents,

My Subaru Impreza is older and is a little bit of a fun vehicle. I recently hit a pothole while drifting through a puddle/mudhole. My car began shaking and pulling to the left. I initially thought it was a flat tire because of the pull/shake. But after an inspection, I found it wasn't and started to drive home. Upon acceleration, it stopped. It was off and on on the drive home, then went away. It was gone for a couple days, then resurfaced, only at low speed and while not accelerating. My steering wheel is also slight shifted to the left while tires seem to be straight. I am not sure what's going on. Please let me know your thoughts. Thanks.
