A case for the magical vanishing -- and subsequently reappearing -- steering fluid!

Ideas?

Yesterday I did a bit of driving around. When I arrived at one of my destinations I noticed my power steering pump was making a whine. I opened the cap and noticed the fluid was just to the bottom of the reservoir tube, but still lubricating the pump. With a few more stops to make I continued on. By the end of my last stop the pump was groaning and steering was difficult -- it had run very low on fluid.

I got home, filled it back to it's normal level and drove again, only to find my engine smoking when I stopped again. Somehow now the pump had found that lost fluid and belched the fluid I had just added all over the motor. The reservoir tube was now filled to the top with fluid.

What the hell is going on?

The fluid got air in it when you ran low on fluid, the air displaces the fluid volume, then when you added fluid it caused it to puke back out. You probably have a leaking rack, steering lines, etc... I would check the rack first, if you haven't changed it out yet. They end up with swollen boots filled with P/S fluid.
Boots look good, can't find any obvious leaks, there's no marks on the driveway to indicate any leaks... This was a sudden happening too.

Shes dead, Jim.

Pumps got a permanent whine and it's shooting fluid out whenever I turn the car off.


GG. I'm too broke to fix it, so I guess I'm out a car

Edit - And yes that is a C-Clamp holding the DPFE sensor on. The bolts sheared off trying to remove it at one point.

The issue seems fixed!

Here's some pics for you to gaze over

Obviously, secure the vehicle in the air.

Remove the tire and locate the passenger side rack boot. You'll be removing this, so be prepared to cut the inside clamp off. If you're careful you wont break the boot.

Remove the two clamps and slide the boot towards you to expose the prize. It's this "plate", with four holes in it. In my case, and the others noted in the thread I linked to, mine was loose. It took four full turns to tighten it back up.

With the plate tight, slide the boot back into position, reinstall the outer clamp, and install a new inner clamp.

My boot was full of power steering fluid, something I don't believe it should have been. I bled the system annnnnd no more spraying, and no more loud pump! Holy crap I just saved a ton of money!
