I have an 05 LS430 and now that its warmer outside the rear sunshade squeaks when going up/down. Is this normal and what is the preferred method of lubing? I just had my mirrors and smartkey system fail so if I can prevent breakage I am all for it. If there's no problem then I'm not too worried.

The squeak is really minor and happens when the shade is near the middle of being opened/closed.

 

I hear a very minor squeak on mine at the same point in the movement you mentioned. And similarly it did begin with the onset of spring weather. I think it might be a plastic part expanding with the temp and I'm not overly concerned by it. With that being said I'd be interested to find out how to lube it for preventative measures.

 

No tips guys?
