I have a power steering problem the service centers at banawe and even Honda casa itself can't solve.

It is stiff only the first 5 minutes in the morning.. then ok na the rest of day.

What could usually be the cause? The steering pump still sound good they (even Honda) say. I got a pressure hose replacement (hose going from power steering pump to rack and pinion) when I got it serviced 2 years ago. But there has been no morning stiffness.. it only started this year January 2. Honda told me to use original which has bigger diameter instead of the replacement because mahirap mag pump daw kung maliit diameter.. but why didn't the problem come out the past 2 years. Sayang naman if I changed to a 13,000 Honda hose and the problem still there.

Has anyone encountered this? ano possible cause? I read in internet if the rack and pinion is going bad.. it has this symptom.. I got my rack and pinion changed 2 years ago using replacement too. Original costs 50,000.

Any theories? Any experiences?
