Those PS units are nortorius for leaking..........The design was changed in 98+ models for "supposedly" great improvement. We'll see........
I flushed my PS fluid out the first month I had my 99 LS. One reason they leak, I believe, is because the fluid isn't kept fresh like most every other fluid in the car. I'll flush it out every year now.
We change are oil regulary, @ 30K - tranny, brake, coolant, diffy,.........so why not the PS fluid too....... Neglect is a major culprit :chairshot:
