Hey Folks
Ford is replacing my PTU under warranty, they say once the fluid thickens like whipped cream the unit is done!! I have it on the sly to change fluid every 10,000 miles MAX. Depending on the use/abuse you give it. You can use a vacuum pump available for commercial use on the internet for about $100 and it has enough suction to remove the oil as long as it is still oil! We use one in our shop all the time.
As a bonus, my steering rack has been replaced today, new leather seat cover being replaced, interior door handles on recall and minor rust spot in truck being fixed, all under warranty. Complete with a rental at N/C. I guess I'll see my SHO in a couple weeks.
UH, alpine_jack, you have industrial mouth wash? That stuff is nasty!
