i bought my second 4th gen 4runner two months ago. ('06 LTD V8 nav.) it came with an "autonation" 60 day powertrain warranty. I took it in for an oil change and wanted the tech to listen for the "driveshaft thump." he couldnt hear it (but it was documented for the next visit.) A month later, I bring it in and state the "thump" is becoming more frequent and louder. It was almost as bad as my '03 limited v8. I mentioned there was a TSB. he tried to look it up, but he couldnt find anything. I provided him the lexus tsb with the correct part number, he said i owned a 4runner, not a gx470. I VERY politely mentioned "it is the exact same part.".....and then asked " is it common that lexus owners get better service than toyota owners?" part was ordered under warranty, picked up the truck yesderday...... no thump.
