I did do a search, here and on Google, I read for an hour or so but did not really find what I am looking for. The PS pump on my truck is leaking. I already replaced the pressure hose about a month ago, now I will just replace the pump, return hose and pulley all at once and hopefully be done with any power steering problems for a long time. I did read that a lot of people use the Maxlife PSF but all I could really find was posts that said it stops up leaks and a few people said it made the steering quieter. Is the Maxlife PSF really all that much better than ordinary plain PSF? I plan to flush out all the old PSF by removing the return line at the steering rack and then working the steering wheel back and forth to force the old PSF into a drain pan, then put in all new PSF when I install the new pump. I have 148,900 miles now on my original pump and steering rack, and all it has ever seen is regular OEM PSF. Should I really be concerned with the seal conditioning and other properties of the Maxlife PSF? If the Maxlife really would be better for my steering, I will use it. Thanks for any info on this.
