Default Vibration around 40mph?

My car started having this problem recently.

When accelerating from around 38 mph to around 48-49 my car will shake or vibrate. It happens in any gear from but doesnt happen before or after those speeds.

It only happens during acceleration, coasting in nuetral or off the gas, it will not happen.

Any help will be appreciated. Thanks

Worn CV boots, rebalance your tires?

i think a bad balance will be vibrating at specific speed, in spite of accel, decel, or coast. so thats ruled out.

Not unbalanced tires - speed too low. Not misfire - happens at same speed, any gear.

CV joints a possibility.

No, it means you need new CV boots.

Soo many keyboard mechanics, that are wrong.

It's not misfiring.... If it was, you'd have a check engine light on.

It's not the CV boots, they just hold the grease inside the CV joints. Boots don't cause a vibration.

Not the wheels/tires, or the vibration wouldn't go away under decel.

It is the inner CV joints, as seen here:

Since the pic of your car is stupid low, it will probably reoccur.
