Q: Q: Vibration during acceleration

asked by on

While accelerating, my car vibrates - it feels like I'm driving over small bumps in the road. But, the vibrating smoothes out when I get to a higher speed, above 50 MPH. The issue is especially pronounced in 3rd or 4th gear going between 30 and 40 MPH. The tires are equally inflated, CV joints look OK. Does this sound like a transmission or suspension problem?
