umm wondering about lower control arm is that do you need to mark which side is passenger and driver side, and which side is facing the front of the car(on control arm, like what side is facing the front of the control arm and the back)

 

Yes, they are L and R pieces....

 

so ur saying they are already marked? and can you check this diagram out rynberg and tell me about this kind of confused

The stopper should be towards the rear of the car. I think it actually has "REAR" printed on it somewhere.

And BTW, the rear LCAs are interchangeable.

 

k awsome thank you that clears everything up!!
