Back in 2006 the power steering on our 1998 DGC was getting a little noisy so I too was faced with the ATF+4/Power steering fluid conundrum due to noise. I ended up evacuating as much of the old fluid out of the reservoir and refilling the system with ATF+4. The process quieted the steering down considerably but not completely; I'd say it knocked off 90% of the noise and that was good enough for me. I did this when the van had just over 100,000 miles on it. When I sold it with 180,000 the system was still operating perfectly and (mostly) quietly with no leaks or other ill effects from the ATF+4.
