So when I make turns at slow speeds, the truck starts whining and I don't know what the deal is. A little background, the pickup is a 2008 F150 SCREW 4.6L 2WD, 36k miles. The TPS came on today when I was on my way back from work and I started to noticed the whining when I went to pick up some brews. I'm almost positive the tires aren't the issue because I had some Yokohama's on it before they gave me lots of problems and I got a great deal on some BFGs. I get problems when I make slow turns into a parking spot or like making 3 point turns, and it's not only whining but the truck becomes hard to turn, sort of like my old Farmall on pavement. The truck is under warranty still, but I don't want to take it to the stealership (I used to put up with them when I had my '97) and they amass all sorts of problems or keep it forever because I can't afford to be driven around for weeks. Any help is appreciated

 

same thing happened to my 08, pump went out at 56000

 

Sounds like the power steering fluid is low. Top it off and see if that helps. Might have a leak...

 

I'll check the fluid in the morning when I check the tires, top it off if needed and look for leaks since my truck will be parked all day since I gotta study...in the case something has gone horribly wrong I will take it in, though I hate to wait till thursday when I could find time to take it into the shop.

 

Just a heads up: sometimes, it only leaks when the wheels are being turned, so just letting it sit may not show drops on the ground. Good luck. :-/

 

Thanks for the tip I'll keep that in mind tomorrow.

 

My truck does the same thing. I think its the pump but I'm gonna wait untill it gets worst before I replace it.

 

So I checked my power steering fluid the other day and it was about a 1/4 inch below the min line. Is this why it's having trouble turning? I haven't noticed any leaks but I'm still monitoring it. I went to dealership today and they won't be able to get it done till next week. Also, if I add some ps fluid, do I have to use Motorcraft?

 

i would use lucas powersteering fluid... or something like that...

my powersteering pump and rack and pinion went out at 14000 miles....

 

But is it safe to mix the Motorcraft stuff that is already in it and Lucas, or any other brand?
