Foamy power steering fluid???

I started my jeep, turned the wheel, it made a sickly groan, I opened the power steering res. and it was foamed up... what the hell is this!!!???



On a side note, it has been leaking very slowly lately from the pump.

It'll get foamy when there's air in the system, as you're likely to have with a leak or a low fluid level.

Let it settle back down to fluid, check the level, and top it off. If you're lucky, that'll get you running actual liquid again for a while. If not, start by fixing the leak and move on from there. The steering gear doesn't like running on foam, and those puppies ain't cheap.

Thats what I figgured. DARN. Well it is leaky, so that may be where the air is coming in. GREAT. Any idea how much a new "puppy" (pump) would cost??

It could be leaking from a hose connection to the pump. Once it runs low on fluid it will foam up as air gets sucked in

just top it off and then turn lock to lock a few times and see if it helps.. check the junkyard if you want for a low mile pump or hit autozone/napa or something

Napa pumps aren't that great - I'm wishing I had gone with a mopar pump, whether it was from a yard or a dealership. Pricey though - about 300 bones.

Bleed it before you do Neil - Stop to stop, don't quit at either end for too long or else you could hurt the pump. Check the level frequently.

Hoses can leak too; either the pressure or the return hose can leak.
I'd recommend if you're replacing the pump to save yourself some headaches down the road and replace both hoses at the same time.

Mine died at 216K miles. That is pretty good if you ask me.

My failure was a complete mess at a completely bad time, on vacation in the middle of downtown DC during the Cherry Blossom Festival with four adults and a child in the Jeep. They all took the train home while I got AAA to truck me back to my brother's house. I did the swap that night. It could have been worse (freeway halfway between destinations).

If you are losing fluid and groaning, I would swap the pump. I had fluid spewed all over the engine bay, and I am still finding individual bearings in the bay.

same thing happened too me.so i flushed my system with powerstearing fluid first.(figuring that will fix it) same thing happened again. tell i found out that power stearing pumps should be running ATF fluid on them. it puts less stress on ur system when it is cold out side
