Power Steering leak

Hey guys,

Hopefully somebody with more of a clue can give me a clue, as I'm an out-and-out sometimes.

My baby's going through a lot of power steering fluid, whether I drive her or not; I'm talking as much as half a bottle a month.

I'm not seeing any spots on the pavement that weren't there the last time I parked, and since it's going down even when I'm not driving it, I have no idea where it's going. The pump is at most 3 years old, as is the rack & pinion...is there any other common leak points for that system? I'm not sure if they have lines that run back to the rear diff for the 4-wheel or not, but I'd imagine that'd be a really easy place for holes to develop.

It's driving me nuts...any help would be appreciated!

Re: Power Steering leak

Your dust boots aren't leaking on the steering rack?

Re: Power Steering leak

A common problem with these cars is the rear PS lines for the AWS. The hard lines tend to start leaking where they come off of the rear pump. Its one of the main reasons people do the AWS delete. It happened in my car and got to the point where I was running through the reservoir once a day.

Start at the rear pump and follow the hard lines..should lead you to the leak

My car developed a leak in the rear lines just off of the rack. What made my leak tough to spot is that the lines are covered in a rubberish sleeve and the hole in my line was covered by said sleeve.

Start the car, make sure the reservoir is full, and then just take the steering wheel from lock to lock with the car parked. This should force the leak to puddle up under the car or at least seriously accumulate under the car. Then just follow the fluid back to its source.

Re: Power Steering leak

Thanks!

I'll have a look over the weekend...I won't have enough daylight to get her up in the air after I get home from work, let alone to go fluid hunting. It sucks being a parking lot mechanic sometimes...

Hopefully it's nothing too ridiculous; assuming the heater core's bad [and not just sucking oil vapor off the leaky rear turbo into the defroster vents, as Dad suggests is possible], it's got a solid $5k in known problems, Hence the 'favorite little money pit' tag on the thread. I am accounting for labor there, as I'd be breaking my lease to do it myself...parts alone, between a third and half that. I love the car to death, but when she breaks she breaks big.

Yet at the same time, I just can't bring myself to get mad at the car. It's rare, it's sexy, it's quick, and even 6 years into ownership I still dream of giving her a new lease on life via a DR19T build. I don't need to be the king of the straight line, I'm shooting for the realm of 525 on-pavement and 1g (or a little over) side to side...though suspension isn't really my forte, so I might have to back that one down a bit.

Thanks again guys, I'll keep you informed when I know something.

Re: Power Steering leak

Good luck. Hope you figure it out. I'm interested in the outcome for my own future reference.

Have I mentioned that I hate being a parking lot mechanic sometimes?

I wasn't able to get under it, it's been raining all weekend. Agh.

I know what you mean. I got tired of chasing the problem with my wife's car in the cold and snow so I finally brought it in to a shop to fix.

I won't be able to fix it myself, if I got caught I'd get evicted...but knowing where it is ahead of time helps me in the long run.

True, then they can't bullshit you that it's something else.

Re: Power Steering leak

VR4GTO:

I promised to let you know what it is when I find it...got a chance to crawl beneath this weekend. I didn't think to look from the passenger side...from the driver's side, the 4WS setup is flat-out soaked.

What are the common leak points for it, and the kinds of parts costs I'll be looking at, does anyone know?

Maybe have the car running while off the ground and have someone turn the steering wheel while you underneath. Maybe you'll be able to see where its leaking

Re: Power Steering leak

My line busted from the rear pump on top of the diff. It was also the lines coming from it and pretty easy to diagnose. Unfortunately requires to drop the diff

I thought firing 'em up with all 4 off the ground would damage them? There's a warning sticker near the info plate about it, but that might warn against being on jackstands and in gear; I haven't looked at it in ages.

Mitsu doesn't know shit. . I can't see it hurting anything if you do it for a short time. Maybe I'm wrong. But I'm not talking to my wife so I suppose I might be right.
