My car is a turbo diesel.

When the car reaches forty km/h and I remove my foot from the accelerator and just let it roll, there is a very strong vibration through the whole car.

It also happens when the car is slowing down without me using the brake, only at forty km/h again.

Once it slows down to around thirty five km/h the vibration goes away.

The vibration also goes away if I put the automatic transmission into neutral, but as soon as I go back into drive it starts again, once again only at forty km/h

Had the tires replaced today, wheels balanced and aligned.

Still happening.
Please help!

This sounds like the CV axles are getting worn/seized and need to be replaced. Here is a guide to help remove the axles so you can check the CV joints for tightness. (They should move freely)

Please run down these guides and report back.
