To close this loop, it wasn't just loose- but needed a new pulley- it had enough wobble that it wouldn't stay torqued- especially with AC on. Made it only 29 miles before a repeat. Don't know if the first "incident" was enough to add wear to the softer metal pulley- but a new one and new nut (and thread-locker was needed.)

My 4 month old to me SC430 lost power steering suddenly, with a clatter- but I limped 1 mile home. Turns out the nut on the power steering pulley was loose and it was spinning. Tightened it back to 33 FP, and all is back to normal. Is this a common occurrence? There doesn't seem to be much other than the nut on the Power Steering pulley pump. Or, should I just chalk it up to carelessness by the technician who replaced the timing belt 80 it so miles ago and quit worrying? Thanks in advance.

I appreciate all the comments on this topic, but all in all, I just hate the antenna anyway. While replacing the factory radio and I had the dash apart- not all that difficult- I installed an amplified bar antenna from Crutchfieldup above the nav screen in a cavity at the far front of the dash and plugged it in. Then I followed the procedure to access the antenna in the trunk- and removed the power cable. Mission accomplished. I have an antenna that works, and one at the back that is very original as if "off"- that never deploys. Worked for me.

While I know nothing about this topic- there is an "F-Sport" included in this forum under the forums tabs. "Lexus RX300 / RX330 / RX350 / 450h / F-Sport Club". Perhaps it is related.

FYI- you can now buy 2K Clear Coat in a spray can- it's a special two-stage that mixes in the can that that provides much better (autobody quality) durability in a DYI scenario. Only lasts once activated for a day or so, but worth every bit of a $25 can. You activate with a "big red button" on the bottom the can- and other than that- it's a regular spray but auto-body quality. Works great for wheels- just lasts longer than all the 1K. Search for SprayMax 2K Urethane Clear Coat. Us Florida folks need to keep our clear hard, fresh and durable. Has worked for me in rehabbing painted silver wheels.
