Unhappy Power Steering Gremlins

I've had the worst of luck in the almost 2 years I've owned this truck. The Power Steering has been a complete nightmare/headache. I've rebuilt the stock pump, then purchased two pumps after that. I've installed a cooler thinking the fluid was overheating thus making the seals leak. I've just recently purchased a new union bolt and washers because it seemed to be leaking from the high pressure side of the pump. I noticed it still seems to seep and fluid is all over the underside of the hood and has started to leak through the passenger fender well. This is not a b!tch post and I WANT to make this work; however my patience is running low at this point. I really don't want to drop $$$ on an aftermarket setup but it may be cheaper than continuing to buy pumps every 4-6 months. I've used Mobil 1 as well as Valvoline Synthetic transmission fluid in the system. I know diagnosing issues over the net is near impossible but just looking for something I've either overlooked or have failed to see on the net. Thanks TW.

Are the Valvoline and M1 fluids compatible with the Tacoma power steering system? The Tacoma calls for ATF (Dex II/II), not PS fluid.


I also had problems on my '04 spewing fluid once I put on bigger tires and front armor. The fluid would overheat. Eventually the seals on the rack started to go, along with some of the rubber lines on the low pressure side.


Can you get the truck good and warm and have someone run the wheel back and forth while you look under the hood and try to find the source of the spew? Some leak tracer dye might help with that, too, if you can see a fine mist coming from somewhere while the system is pressurized.


Other than that, I'm at a loss, save that you don't indicate that you have changed out the rack.

Both fluids I've tried are both compatible. It's funny, doesn't seem like it wants to leak until I close the hood and drive on the road for a bit. It appears to be leaking on the underside of the pump. I don't have any leaks around my rack, it seems to be right at the pump. I'll let it warm up and see if that helps in detecting the location of the leak. Thank you.

I'm leaning towards PSC. I'll look up the warranty info.
