I have a 2010 F150 4.6 3V... The power steering reservoir is constantly losing fluid. I've purchased the truck,used, a few months ago, bought a warranty. The dealership has had it multiple times now and can't find the leak. They just keep replacing hoses and the problem keeps occurring. Also worth noting, the truck has 6" lift with 35s. I've have also pulled the radiator cap and found a decent amount of what looks to be sludge/oil inside. Dealership says it's probably just bad coolant. Any help or ideas of what could actually be wrong, would be appreciated.

 

In my 12 year old '05 F150 I never changed the power steering fluid, and never hardly ever had to top it off. Then two weeks ago I removed all the old PS fluid, and replaced it with Wolf's Head fluid meant for power steering units, and the sales guy said it's meant for PS units although the bottle said ATF. I'm confident I put in the right stuff. But ever since I changed the fluid, now the darn thing leaks almost totally out. The leak is at the bottom where the rubber boot is at the wheel level, accordian type long boot Why did this happen after all these years with no leaks? I think I caused it by changing the fluid. I didn't have a problem before. Thanks guys for your input.
