My Bonny has developed a strange steering problem.
Turns to the right are very stiff, feels like no power assist. Turns to the left are fine.
Checked the P/S fluid, and is very slightly low, but not enough to really make a diff.
Yesterday when it was a little rainy and damp here, worked fine in both directions.
Today it's not as rainy, but have the problem turning to the right again.
Could this the the rack going out?

Does it happen at all speeds, or just low speed. Had a similar problem on a 2000 that started with just right turns at low speeds, and eventually worked up to both directions. A bad pump was the problem.
