Here's waht happened to my wifes 2000 RX300.
When she bout it it was used and had 30K miles on it.
I started changing the oil myself using Fram oil filters.
After about 3 oil changes (around 40K miles) the rear main seal started to leak.
I told her to take it to Lexus and have them check it out and change the oil while it is there.
It still leaked a little. When the next oil change was due my wife went and had it done at Lexus without telling me. The rear main seal stopped leaking. I did the next two oil changes and the seal started leaking again.
I told my wife to take it to Lexus for the next couple of oil changes and let's see what happens.
Well. after two oil changes the seal stopped leaking and has not leaked since (about 1 year).
The truck has 76K miles on it.
I have always wondered if the Fram filters were designed so that they raised the oil pressure to to a point where it caused the rear main seal leake.
Anyway, it's just a story I thought I would add.
Other than that I changed an air/fuel sensor and a thermostat and Lexus put a new coil pack on. I had Lexus do that because it was in the back. I think it's been a great vehicle.

I am looking for the part number for the pins and springs (brake hardware kit) for the rear parking brake shoes.
This is for a 2000 RX300 AWD with disc brakes.
Anyone have it or know where to find it?
Thanks in advance.
Oil Seal Leak

Yes the tech at Lexus did inform us that the rear main seal was leaking but I had already known this.
I thought about the idea that they may have added stop leak or something similar. if they did they never informed us of it.
The Fram filter theory is very weak but it's all I have. I was thinking about purchasing some Denso oil filters and doing the change myself to see what happens.
