i have a similar problem
i dont have no juddering but since i changed the two front wheels over from one side to the other the car now pulls to one side more, the reason i changed the two fronts from one side to the othe ris coz the suspension is exactly 1cm higher on the passenger side front only?

and nobody can see any faults, it was wearing the tyre down on the outer edge. so i swapped the tyres over as the drivers side will need chaging soon anyway so thought id put it on the dodgey corner
prior to changing the wheels over it was perfect
im changing the whole suspension soon so that will solve it so im not too fussed but would be nice to know why its like this
