have anyone have the clunk noise come from the front passenger side when you slow down about 30 mph, and the clunk noise only hear once, but every time I slow down from higher speed and I heard clunk noise, just one clunk, sound like the sway bar link end, or the strut loose? but i only hear when I slow down from the speed above 40mph, that weird

 

This could be the famous THUMP noise from the transmission. It happens on a slow down at ~ 30 mph. If it is, there is a TSB on it. Sounds like a thump or a clunk.

I did the TSB since I missed the warranty limit. I did a DIY on it. Parts $50 and takes 1 hour to do. Do a search on clunk or thump.

 

yeah i think that sound, what is TSB warranty for? my trunk now 29,000, but it 04 can you show me how to fix that? thanks

 

Do a search, I posted a DIY.

 

For the first couple of weeks that I had my RX350 I had the craziest noise. It wasnt loud but you noticed it. And it only happened when I applied the brakes. I looked all over the car to make sure nothing I had put in was loose.

Then I had my parents riding in my car. And I noticed the noise wasnt there. It was the front passenger seat belt banging against the side of the seat.

 

I had the same thing on my 05 RX330....weird and persistance noise....my wife fixed it with some cloth and velcro, as I recall.

 

My noise was the plastic cover of the roofrack on the front of the rails, driver side. Will be fixed under CPO warranty shortly...
