Recently purchased a 2005 Bonneville GXP with 104K; other than an engine/transmission mount issue I have now noticed stiff steering when making a sharp turn at slow speeds; usually after the engine is warm. Fluid level is good and the ps fluid is not dark; I work at a local Honda dealership and the Honda Odyssey has a similar problem (stiff steering at slow speeds) in which we have been replacing power steering pumps and reservoirs and flushing the system. Can I expect to do the same to the Bonneville? Anybody have or have had this problem?
Thanks for any assistance.

Re: Power steering issues
Had similar with a 00 SSEi. Replacing the pump solved the problem.
