Vibration when slowing

Hi
Had a quick look at some threads just need a 2nd opinion from the freelander doctor. I have a noticeable vibration when I lift off the accelerator or start slowing down, the brakes have all been renewed, I've had a new Rear Diff and mounts new rear left hand sub axle, the only thing left is I've lost one of the ABS rings at some point, but the vibration is it being caused by the VCU ?

Problem turn out to be the bearings had gone on the IRD end of the prop shaft plus the VCU bearing were on there way out, fit a 2nd prop shaft everything now run fine.

thanks for the update Morse, well worth knowing that cure
