I ordered my parts from:

Its not necessary to have a lift but it makes the
job a whole lot easier.
I wrote up this tutorial since I couldn't find one elsewhere on the Web.  WWW.Lextreme.com has a nice tutorial
for the LS 400, however, the LS430 is substantially different.   I think the LS400 is a non-interference motor
but the LS 430 is an interference motor.  You definately don't want to wait for the timing belt to break.   I
figured there are a few Lexus owners that maintain their own cars.   The shop quote for labor alone was about
$1200.  OEM parts are around $500.  Aftermarket parts about half that.  It is probably and 8 hour job for an
experienced technician.  It is about a 12 hour job for an average shade-tree do-it-yourself guy.  For a $100 an
hour I'll tackle this job.  Below is a combination of the factory service manual along with photos to further clarify
the steps.
