Is that to say you keep going through PS pumps, or just that your having problems with your existing pump?

Odd, what kind of cooler do you have? What kind of driving do you do? What kind of fluid are you running? How often do you check the fluid level? Sounds like you would be a candidate for the resevoir extension mod.

Are they flushing it out between pumps?

If not that's the problem. The shavings from the previous pump is eating up the next one...

ps pump

I put a small trans cooler in the system. this has been the 3rd pump in less than a year. I am running 33" tires with a air locker in the front. I only use the front locker when I really need it. I have flushed the system realy good every pump change.

Pretty sure that this shouldn't be under cheap tricks.

use dex III tranny fluid it is the same thing as power steering fluid but higher heat capabilitys and better lubrication and power steering fluid has a tendancy to foam or bubble up if shaken or overheated and the bubbles (air) prevent lubrication/cooling.... just a thought, goodluck

Most people just flush it out and wtf does your truck having abs have to do with draining the power steering?

pump runs through the abs accutator so the computer can take over braking when the tires start to lock, duh.
Search.

Wrong section too..

Ah fugit, I'll search for you.

Seems like having the truck off is the easiest and safest way...

fyi... computer figures out if wheels are locked thru the abs sensors located at wheel hubs, NOT thru power steering system in any way. and if you trace the power steering lines you can see that they go from pump to the steering rack and back, with no detour to the abs system.

do you want me to take pictures, this isnt a tacoma btw its an old school pickup with abs and to me it looks like it tell if the wheels are locked through the front differential, because it has automatic hubs it tells when wheels are locked in the diff, theres al kinds of wires running to it, it the sr5 model too if that makes a differnce and there is no wires running to the hub, and I have lt so it cant be hidden in the a-arm or somethin, but I could be wrong on that, my power steering pump runs to, what I think the abs accuator and then runs to the actual steering box, if you follow those lines on that abs acctuator it goes to the front brakes, how else would the computer pump the brakes, without a pumping souce(power steering pump)?

I didnt look at your sig and see you are driving a 94 yota not a newer taco.
The power steering lines do run to the abs actuator on those which controls the brake pressure by relieving pressure in the system when a wheel speed sensor detects lockup. I have never done much on one of those older abs systems so im not sure why the ps lines are feeding into the abs actuator. I dont know if there is a pressure accumulator in the system like there is on a lot of older domestic vehicle abs systems.
