Q: Vibration at 35 mph

asked by on February 09, 2017

My car has 115000 miles.
My car has an automatic transmission.

Hi there. This is very odd, as typically when a mechanical component is damaged, the vibration or rattle will progressively increase as you accelerate. In most cases, a tire / wheel out of balance will cause this type of vibration, or wheel bearings that are damaged. It’s also common for a CV joint that is wearing out to cause a vibration around the same speed. I think it’s a good idea to have a professional mobile mechanic come to your location and complete a car is vibrating inspection.
