Help! Have a lovely 1999 Lexus LS400 with a groaning steering wheel. Had the mechanic diagnose it, power steering pump. They replaced the pump ($545 later) and I still have the same issue. When I picked up the car, they showed me it was still making the noise and thought perhaps there was still air in the system that needed a couple hundred miles of driving to work it out.
Well a couple hundred miles later, I still have the issue.
Any ideas folks? Please help a little old lady out with your wisdom!
