I noticed recently that when I opened the sunroof no matter the position it would have this shaking sound more than before.
just washed it tonight, and I saw one edge was sinking while the other is normal. What do you think is causing this? Not sure if any water leaked inside yet.... and if its complex I will send it to a shop.

 

you can compare to the right side.

 

I'd guess something plastic broke in the track causing both issues.

 

What part of Cali do you live in? Looks like farmland, you only find tracks of land like this either in Chino, Riverside and San Bernardino Counties, the Central Valley (Exeter, Visalia, Fresno etc)

 

If you tilt the sunroof up. You can remove the rubber bellows. With this you can view if the track has a broken hinge on that side. Like mentioned already I suspect a damaged hinge.

 

norcal, placer county

 

For some reason I was thinking you were towards SoCal, but I was way off. We are almost neighbors! I am maybe 2 hours or so from you. I was in the Santa Rosa area this weekend just West of you

 

its a nice little pocket up here I'll tell you that much, and I know theres some sac and other folks with an is who are active here as well.

 

Would a damaged hinge be something I could diy? Also I noticed the tracks had some sort of white grease on it could I get that from lexus or is it a generic grease?

 

Im sure there are other products out there. I wouldn't throw wheel bearing grease on it as it will migrate and get messy.
Go to oil manufacturing site like valvoline and they have a break down of products by application.
