power steering

I can hear my power steering whine when i turn my wheel. The power steering fuel pump is full. Whats wrong? Thanks :confused:

Could be contaminated fluid. Start with having the system flushed. Most of the P/S flushes I've done fix the whine. Probably 95% or better. If it still makes noise, the pump is bad. Start with the flush, because it will need to be flushed after the pump is replaced to remove any metal from the system.
