D3 a8 feels unstable
 

Hi all.
I'm just wondering if anyone can point me in a direction.
Sometimes, more when going right at 50mph or more, it's like the front wants to walk wide a little before turning in and the back end kinda bobs like it is struggling to settle. Doesn't seem to happen going left.
It's got good tyres, only about 3k on them and the suspension rises and falls correctly. No obvious uneven wear however the previous set of tyres did wear on the inside so I had a 4wheel align done at my local fitter. Might go and get it rechecked at another place.
I've yet to get it in the air to check all the bushing etc as the weather is terrible but will do that later this week.
Thanks for any input.
