Power steering fluid is leaking

Hey guys,

So one Saturday afternoon, I decided to run some errands and noticed sounds coming from my steering, when turning right and left. When I got home, I checked my power steering fluid, which was way below the “X” marker on the cap. I added fluid and the noises went away.

Just to follow-up on the issue, I checked the steering fluid level exactly one week later (while engine was cold) and it was barely touching the “X”.

I've also been noticing prominent spotting underneath the car – to the right of the passenger wheel area, roughly (when car is facing me)

Is there some hose that went bad, or has my steering pump sprung a leak?

What fluid did you use to replenish it?

You could try getting under the car and seeing what exactly is leaking.

I had a minor leak and used Lucasoil Stopleak Power Steering Fluid, and the steering has not lost any fluid since.

I used generic Autozone brand steering fluid to top it off.

I'll have to take a look underneath the car this coming weekend. Last time I checked, I noticed fluid on the passenger side cv boot area.

Thanks for the advice, I've seen the Lucasoil Stopleak Power Steering Fluid at auto parts stores in the past, and I asked myself "does this stuff really work?". Since it worked for you, maybe it'll work for me.

Before we use the stuff that clogs your system (No Offense lingen ). Check to see if you're local AZ has some flourescent dye you can drop in to it. Run it for about an hour or two on the roads, bring it back, shine black light, and find leak.

None taken. I will complain if the steering ever gives me any issues in the future though.

I should note that it's been two years, and my PSF is still A-OK as of Sunday night when I checked it. I didn't add a lot of the Lucas fluid two years ago, maybe a few ounces.

It may be the section of your power steering pressure line which runs from your P/S stump, down the side of the engine, along the length of the steering rack. It's typically running parallel to the radiator by the inner front bumper.

There is a section in this line that I have known to leak - this section is typically located by the passenger side wheel.

There is a section that is metal pressed into a rubber.

This joint where the metal sleeve is pressed onto the rubber is prone coming apart, corrosion, and leaks. Oil cooler lines on some GM vehicles are prone to the same issue. If that is the case, you can go the cheap route and cut out the bad section and splice, or replace the line. I've done the splice job on a beat up old Cadillac using male and female pipe adapters from Home depot, hose clamps, cutting out the bad section and splicing in. It held up suprisingly enough, but I wouldn't recommend it.

A new line is not that expensive and a way better fix.

I just replaced one of those the other day, it's a pain in the ass, had to separate the ball joint and lower the rear of the sub-frame to do it. The part itself was only $38 at my cost though. The problem I had was that the stupid plastic splash shield in the wheel well actually wore through the cooler line, a little pinhole was all it took to make the car lose all it's fluid rather quickly. That being said, the rate you are losing fluid at tells me the leak is small. Check around the power steering pump itself, you make have a leak between the pump and the resevour. (I know I spelled it wrong)

I've got the same issue...damn splash shields! I havent dug deep enough yet to see how its connected. Is it a crimped connection, b-nuts? fortunately I have access to a lift. I just want to know how easy it is after the ball joint and the sub frame disconnect.

Can't recall exactly at the moment, but I think one clamp and one nut. You'll know when you look at the new part. It has the big solid loop that goes on the front of the frame rail, and the hard lines go 90 degrees around into the wheel well. Then one goes up, and one goes back around to the rack.

Question Francois

I've been trying to find the leak in a 2006 Impala. Finally took the pump off the engine and found the leak at the pressure line fitting on the pump itself. The "O" ring was baked and flattened so I replaced it but still leaked. I then replaced it with a larger cross section ring but the leak persists. The line was replaced with a new one and the pump replaced four times. Frustrated and bamboozeled over this one.
Is there a possible fault in the steering rack itself that overpressurises the system causing a bypass situation at the pressure fitting?
I'm out of ideas on this one.
