No Power Steering Still After Pump And Gear Box Replaced?

[72Rockcruiser]

So after a short wheeling trip a while back with the front locker engaged(and 38's), my 97 Land Cruiser has had no assistance from the PS.

I have(finally) replaced the pump, installed an overkill cooler, and even replaced the gear box. STILL no PS?

Also filled with new Royal Purple fluid. Thanks Will!

I am stumped. No noise, no whining, no bubbles in the res. Turn the steering wheel lock to lock with tires off ground, no binding.

Just no help from PS.


Any help is appreciated.

Thanks!

Did you blow out the lines?

Good call, Alex. I did order a new pressure hose, thinking it may be blocked, the return line is no longer available, so I will blow it out when I replace the pressure hose.

This is pretty much the last thing keeping me from going wheeling, so wish me luck!

Where did you get the pump/what brand? Rebuilt pumps actually work about 1/4 the time in my experience.

Low mileage used factory Toyota pump. Did not buy an aftermarket pump for that exact reason.

Also, may be important to add, this engine (1FZ-FE) uses a gear driven pump driven by the timing gears.
