I have a 1996 Chevy 2500 Suburban with the 454tbi.

It leaks. A lot. I know it leaks power steering fluid, but it appears that it doesnt just leak in one spot. Looking at the ground under it after I park it...i have a spot under the steering box (I know they are notorious for blowing that seal out...so i need a good source for a rebuild kit (chain store?)), I have a spot underneath the front of the oil pan (could be blowback off of the power steering while driving), and I also have several smaller spots that accumulate under there getting slightly larger over time (front of motor and front driver side mainly with the oil pan area dripping too (rear main seal?...god i hope not).

I'm not sure where else there could be leaks in this thing...but the brakes also arent that great which leads me to believe that there is a hydroboost issue as well.

Its hard to pinpoint the leaks bc there is just splatter all over the driver side of the motor from the power steering fluid that is everywhere.

Any ideas as to why this thing just dumps fluid out all over the place? This is my first Chevy (im a toyota guy) and I dont know what the problem areas are on these things nor where there are good sources for parts (if its anywhere different than chain parts stores).

I can get a steering box rebuilt kit from the parts store...should I go that route first and see if that fixes it?

Thanks in advance!
 
Are your lines tight?

Is your return to tank hose in good shape?

Is there fluid between the master cyl. & hydroboost?

Did you ever over fill your pump tank?

take it to the car wash & blow all the oil & crap from around the master cyl & power steering pump. Drive it around & then check for leaks.
 
if you run your hand under master cylinder/ hydro booster and your hand comes out orange you need to replace your hydro booster.
 
i have a 95 3500 and im in the same boat. do your self a favor and replace all the power steer/hydroboost lines as their probably due. clean everything with gunk and check for more leaks after a few days. i have let my hydroboost leak and now my rear upper control arm bushing is shot due to all the ps fluid leaking on it.
