Ford Escort b5 gearbox/diff issue??

this gearbox is in my mk6 2.0 zetec escort, its started pulling quite hard under load, watch closely you can see the diff osolating out of round, would this cause it to pull over to one side?

Diff bearings are shot, wouldnt make it pull tho, You got the right size tyres on both sides? check your subframe mounts and TCA, track rod end, wheel bearing,

since i made this vid, ive renewed the osf wheelbearing, both wishbones, both track rod ends still no improvement, its better tho.n 195/50/15 steelies all round. anyway lifted the carpets and the subframe mounting points have gone soft, game over i think
