Good evening everyone.
I've been trying to identify the part in the attached photo. I've been searching the internet for a couple of days with no luck. There is a bolt that I tried to tighten and it broke. So I need to replace the part.

It is right in the middle of the rear frame.
Any help would be appreciated.

Thank you.

2010 Lexus RX 350

 

That is a vibration damper. They tend to get rusty. If it is gone you probably will not notice any increase in vibrations etc. It is not something that is often replaced. If mine fell off I would probably not replace it.

Try searching the sites of the OEM Lexus parts dealers. The one below lets you enter your VIN to find the exact parts.
