When going over large bumps and dips I'm hearing a very high pitched squeaking noise coming from the rear end. Over small bumps I hear nothing, it's only the large bumps where I hear the squeak. Anyone else have a similar problem or have any advice where to start troubleshooting?

Rear anti roll bar bushings is the first place I'd look. They're easy to access once you remove the wheel. Try spraying a bit of silicone lubricant into each where it contacts the bar.

Most likely it's a bushing.. Get under there and spray some silicone spray on a couple bushings at a time and then go over a bump.. One you find the culprit either smother it in spray or (preferred) get some actual lube on the bushing.

Mine does that on the front driver's side. It started after I had to drive for a few miles on an unpaved "washboard" type of road. It's highly annoying but I haven't had time to troubleshoot it yet. If it is bushings, does anyone know if that would be covered under the Lexus Platinum warranty plan? Or is that considered a wear & tear item?
