If the steering box is only loose at the centre then adjusting it will make it tight when you turn left or right. If it is loose all the way from lock to lock then it can be adjusted.
Sometimes they come loose, my LSE was like that, but the original supplier didn't even trust LR mechanics to adjust them, under warranty the whole box had to be swapped and returned to the manufacturer for adjsutement.
Unfortunately though when they wear it is only in the straight ahead position, in this case it can only be fixed with a recon/new unit.
