I have a solution to the power steering problem (and I intend to get flamed for this suggestion) which is to delete the power steering pump and circuit completely. I did this three years ago, and I have very positive results to report. You'll only be (by my estimation) needing 20% more force required at parking speed to steer. At any speed about 10 MPH, you'll not notice a difference.
Good reasons for the deletion:
- Less complicated system.
- Easier to work on the engine.
- No more leakage of ATF on alternator.
- Better cooling (without more stuff under the hood.)
- No need to buy discontinued parts.
- Better feel for the road.
- One less belt and pulley.
- Better MPG.
- System can be reinstalled if wanted.
Here's the engine space without the pump and hoses:
