Did you find a solution?
My car has the same problem. The steering play is tight (which is what it should be) when wheels are straight. But when the wheels are pointing either left or right, there is excessive steering play. I check this play when the car is stationary.
I wonder if the steering play has something to do with the tires. My front tires are a little worn on the outer edge.
Were you able to find a solution?
