I recently purchased a 2016 rc200t. It was wintertime and cold. Everything was fine. As weather warmed up, I noticed a squeaking noise going slow over speed bumps and potholes coming from the front end. Higher speeds nothing. I changed out the sway bar bushings, but it was still present. I had a Lexus repair shop look at it and they said it didn't appear to be the struts nor the upper or lower control arm bushings. They ruled out the sway bar being the issue and said brake calipers seem fine. They thought maybe it was subframe bushings but want more money to continue to investigate. I said thanks but no thanks and took the car back. I've been under the car looking for anything I'm missing. Everything seem tight and I don't see any leakage indicating something is bad.
Having not heard anything until the weather started to warm up and it is coming from both sides and only at slow speeds has me up at night. Has anyone had this issue before?
Any help would be appreciated.

Thanks

 

what size sway bar bushings did you use?

 

Energy suspension 9.5112g
Universal sway bar kit
Fits sway bar with diameter of 1.125"

IPC LS 17161 and 62 sway bar links
I tested the ride without the sway bar on and it decreased the squeak slightly but didn't eliminate it. I had the new bushing so Installed them anyway. Squeak still exists

 

It’s probably your sway bar links. Go oem or get sankei. The ones you got (I assume oreilly, are plastic lined joints/poly). Did you grease the sway bar bushings when installing it?

 

wasn't sway bar. I drove around without it on and still had noise
