Another ps thread sorry but i just cant find what im after

[White ls400]

My power steering is leaking from what looks like a valve that sit a top the steering rack(right hand side on a rhd). it has what looks like a circular nut(may be wrong on some details has been 2 weeks since looking at it) on top of it and looks like a seal has let go, can you buy individual seals to replace these as i dont have the time to have my car off the road to reco it

Looking at yoiu avatar you have an LS400 or Celsior.

Go to you local frinedly Lexus dealer and have a look at the parts manual.

They are surprisingly friendly/helpfull for someone who is about to bend you over the counter and rape your wallet.
