two issues: loud creaking and squeaking
 

I have a 2008 RX 350 with 60,000 miles. Issue 1. -Anytime the car rocks forward at a stop or when I have placed it in park, it literally sounds like it is moving on rusting, creaking bed springs! This is very embarrassing. I have taken it in for service and told them exactly this and the tech looks at me like she has no idea what I'm describing. It sounds like something needs to be greased but I don't know what.
Issue 2- There is a loud squealing/squawking that comes from somewhere in the engine. It seems to be assocaited with the ACor some kind of belt but I cannot confirm this 100%. If I turn the AC off, sometimes it settles down, but not always. I have also taken the car in for service related to this problem and once again, they could not figure it out. Its been making both of these noises for over a year now. Thanks for any help you can give me!

There is nothing to grease on these vehicles. At my dealer, the service tech will ride with you so you can describe the problems firsthand, maybe you could try this.

I had my accessory belt squeal for a week or so after I accidentally spilled some engine oil on it. It cured itself. I would guess you need a new belt, the Toyota dealer or independent shop can do this for you if you don't want to pay the Lexus premium.

Let us know what happens next...

thank you for the reply. I didn't think anything could possibly need greasing but I could not make sense of this bed spring type creaking! lol. My sunroof also rattles but I gave up getting that fixed because it rattles worse now than after they supposedly fixed it the first time. :{ What is an accessory belt? thanks!

Its the belt that powers the alternator, a/c, water pump, etc... They are easy to replace by a competent shop.

Thank you for your help!:)

sorry, i have to revive this thread again. I am get the same noise, most especially with the A/C is on. I just got my RX back last a coulple due to another squeaking noise coming for the windshield wiper tray (from what i was told, they fixed the issue). Could it be something else besides the belt??
