Thanks for all of the imput I bought the ps pump from autozone, and after looking at the old ps pump in my ls for 3 hours, I finally called a mechanic who said he would install the pump I bought for $80.00, sounds good to me, it took him 3 hours to remove and replace the old pump, This was a lot cheaper than dealing with the Lexus Service Mafia, That wanted to charge me 782.65 for the same part and job.
