I have a problem since 2 years with steering at lower temperatures (below freezing). When the car starts in the morning steering is very stiff and hard to manage, almost if there were no power steering at all. Then after 5 miles driving the steering becomes slightly better, after may be 10 or 15 miles it seems to be back to normal.
I have exchanged the PS fluid and filter with no change.
I also loosened the screw at the steering box slightly with no outcome at all.
During spring summer and fall when temperatures are moderate above freezing I have no problem at all.
Does anyone have an idea what the problem might be? Is it a bad steering box and what would cause freezing of the steering in the box?
