You want us to pinpoint your leak? Not to be a **** but, how can we see where it's leaking from? It could be a number of different places that it's leaking from. Get underneath it, take the bottom engine cover off, (if you still have it) park it over night, see where the leak is dripping on the ground and look up. The highest spot where there is wet fluid is more then likely your leak. You can also look at this link, it will tell you everything you need to know. https://www.clublexus.com/forums/ls4...ing-bible.html Oh yeah, Welcome to Club Lexus.

One of the many usual places the pump leaks, which flows onto the alternator, is the ACV valve located on the bottom of the PS Pump. Use the search button at the top of this page and put in "ACV valve" and you'll find pics and info on what to do with it. Also both of my PS pumps have leaked from the top side. If you look at #6 in this, http://www.lexls.com/tutorials/steer...mprebuild.html , that's where mine leaked. All these leaks are very common and talked about alot, ya just gotta search for it.
