A worn in-board CV can cause vibration under acceleration, but it can't cause a whining noise.
If it only started after replacing the VCU, then you need to question the VCU, or other factors like tyres. Unless the VCU was new, or was reconditioned by Bell Engineering, then it needs testing with the One Wheel Up Test. Also you MUST have 4 identical tyres, with least worn on the rear.

Hi yeah was a bell engineering one and the tyres are all worn the same but the pressures were different and I pumped them up to all at 35psi but haven't yet trailed it out yet. I did drive it for a bit as a 2wd until the garage put the bell engineering one on. It's bugging me
That's good.
Are the tyres the same? Same make, same type?
35 Psi is too high (the correct pressure is 30 Psi), but more importantly all must be the same pressure.
It's vital that the tyres are the same, or the VCU will cause wind up, which will destroy the IRD.
My guess is the IRD is complaining about the tyres being odd.

I would do a 1 wheel up test - given experiences (mainly from a few years ago now) Bells are the best recon VCU to go for, but they are not infallible, so a test would be a sensible thing to do.
35psi is to high for most tyres. However, I run Maxmiler tyres on mine that by the book should be pumped to 40psi, I run them sightly under that on the Freelander though. So check with the tyre company on what is the best pressure.
