Don’t forget part number 96711-19019

PSPumps

My power steering pump decided to self destruct 8 hours down in Baja on a particularly muddy stretch of trail. Weird thing was there was no fluid loss so at the time I was convinced it had to do with the steering gear box (which I also replaced).
Thick mud down in Baja

ORingLong story short, I replaced pump which fixed the power steering and drove it home from Ramona. Unfortunately next morning I was greeted with a large puddle of ATF underneath my LandCruiser and no power steering .

Seems there is a very small o-ring, part number 96711-19019 , which I failed to install. Funny thing is had I looked at the actual diagram I would have noticed it…. guess that is why they say RTFM.
