coming out from the rear right wheel area when I go over humps or uneven roads. anyone knows where it might be coming from?

 

The right rear.
Seriously, first check your lug nuts and make sure they are tight. Then you have to start looking at the suspension. Anything loose? Could your shock be bad and you are bottoming out? I'm assuming this is a recent thing and that you didn't just get new tires or do any new suspension mods.

 

Looks like the tyre is hitting the car body walls. Not too sure if it's alignment problem, suspension or something else...

This set of wheels has been on the car for slightly over a year.

 

go back to LS... ask them

 

Problem fixed... went back to MM to have the pair of rear suspension changed... the service consultant says that my old pair was leaking oil.
