Whoops, you don't have a box, you are Rack and pinion,
no ball in there, you have an issue with your pump or the
valve body on the R and P unit,, not sure on those, might
not be the unit but a control for steering effort, some of
the newer cars have a thing that boosts the power level
for parking (slow speeds) yet reduces the power at freeway
speeds for better feel. Not sure you have that built in to the
Zuk but I would check it out, along with some recall info.
I replaced the R and P on the wife's car PITA, had to drop the
sub frame, find a used R and P unit, spent hours dicking with
it, to find out the dealer would have done it for free, there was
a recall and they would of done all the work
