Power steering fluid shooting out the cap?

Was going to fill the truck up with diesel before going camping this weekend and heard a strange whining type noise a few hundred feet from the driveway. Wasn't sure what it was as it was OK last night. Pull back into the driveway (less than 1/4 mile of driving), pop the hood and there is fluid shooting out the hole in the power steering fluid reservoir. We towed a 3000lb camper about 15 miles to my house last night and it was totally fine, no issues steering, no noise. Never had any steering issues.

Cleaned up the mess, started it up again. No noise until I start turning the wheel then I hear what I guess is the power steering pump whining and the fluid comes out again. Open the cap and the fluid is all foamed up in the reservoir.

Any idea what could have caused the problem?

Truck in an '05, 159,6xx miles on it. Its been deleted, blue spring mod, gearhead 8000lb tow tune (trailer is about 3k pounds)

suppose to head out for the weekend in about 4 hours

thanks!

Looks to be fluid dripping from what I guess is the power steering pump, on the bottom where a hard line goes into the pump. No idea why they would just start leaking though???

A leak =low fluid=air in system=fluid coming out of reservoir. Fill it, bleed it, enjoy your weekend. Come back and replace the pump.

I think the pump shaft has failed, fluid seems to be coming out of it from what I can tell. Too much of a drip to risk the drive with a camper in tow. Having a shop replace it on Monday (95+ degrees this weekend with high humidity----not even attempting it myself)

The pump can pull air around the shaft seal and foam the oil -- so it comes out the filler cap much like a soda pop if you shake it

Leaking seal could mean a few things, but likely the shaft bearing is worn to the point that the seal could no longer take up the slack

Pumps aren't that bad to take off, but you will have oil dripping in your face to get to the bottom bolts

In my defense, I was unsupervised

General note:
For all those wanting a premium silicone sealer Kubota 70000-73764 is the best your gonna find. This is a hybrid gray silicone that uses solvent rather than acid to start the curing reaction, this makes it safe for aluminum and and any surface that involves coolant.
