Same issue on my '08 RX 350. Boots are not ripped or torn, no drips on the floor. Driver's side boot has a little grease around the end, passenger side had more grease/fluid on the boot. I just wipe it off and keep checking. I ran some Auto RX thru the power steering for 1000 miles, I'm flushing the power steering now with 2 or 3 quarts ATF, then I'll switch to Mobil 1. We'll see how it goes. If all you really need to do is just replace the seals that's a great idea, I have 2 excellent mechanics. Power steering fluid is the most often neglected service at the dealer's. Kinda makes you wonder why with all these problems ? Power steering racks going out at 60-90,000 miles is not Lexus quality to me. Should have never sold my '98 SC 300, best car I've ever owned. I'm 61 and have owned aprox 48 vehicles.
