My 99 has the typical power steering growl. I had a 98.5 that did the same thing and I swapped the fluid with ATF+4. I wanted your opinion on it and if there was an easier way to fluid swap. I vacuumed the fluid from the reservoir, filled with ATF, ran it, then repeated the process until I thought I had mostly new fluid. Ran it for a couple of years with no problem and was noise free. Thanks for amy input.
