you can try a power steering fluid additive that is supposed to help seal
leaks ..
PS Fluid Treatment and Stop-leak,
like at a FLAPS.

basically though ...it's good used rack or  new rebuilt one..
and I am trying to find the time, or the tricks, or the tools to repair one
I have that is obviously a not-very-old rebuilt one..
It was fine, but a pump went south, causing it to leak badly ...and probably
with some good disassembly and a new seal at each end it could have lots of
life left in it.
 so far, I have not heard of anyone taking racks apart, rebuilding them at
home, etc.

Subject: Power Steering Rack Question

I am preparing for a long trip and my power steering fluid has had to be
refilled twice in the last week. I just found the missing fluid in the
passenger side boot of the power steering rack. Can someone tell me if this
is repairable or am I looking at buying another power steering rack? Or is
there a sealer that might work?

Thanks.

Craig
