I have searched this topic and found tons of people with shaking / vibrating problems, but none that matched my symptoms. Under acceleration I can hardly feel it. When I let off the gas and coast it gets pretty bad. When I put it in neutral, it completely goes away. I checked my CV joints and they all look good. I did replace my driver side axel probably 2 years ago. I did notice a small amount of play in and out on that axel. I had this same problem about 2 months ago and after doing a brake job it just went away. Any ideas? TIA.
