Problem Description and Possible Solution
A moaning or fog horn sound may be heard while turning at a slow speed. Installing a finned power steering cooler will help alleviate the problem, but it may be necessary to replace the power steering rack.

Over time trash and debris builds up in this system from wear of parts of the system. There is a screen in the bottom of the fluid reservoir that clogs with this debris. When this occurs the power steering pump is "starved" for fluid and makes a whining noise when turning the wheels especially at low speeds. Replacing the pump will not fix this problem. To fix this problem I bought a new reservoir (about 25 bucks) and replaced the old one. Before I installed the new reservoir I completely flushed all of the old fluid and debris out of the system. I have 220000 miles on my van now and still using that orginal power steering pump.
Moaning noise when turning at low speeds. Did not hear this at high speeds. Thunking noise sometimes heard on tight turns and no response when turning. Mechanic will be replacing just the Rack, not the Pinion for $760.00. Will see if this fixes the issue.
