Is there a way to remove the housings without having to take the front bumper off? I have a sedan but the design shouldnt be much difference between the coupe and sedan designs.

 

Not possible.

 

i got an idea! just drill 4 holes where the bolts are located on your bumper haha. other than that, it's pretty much impossible.

 

if you need to remove the headlights gotta remove the bumper, sorry...
here are the directions

To add a little clarity, if you follow the FSM it instructs you to take the bumper completely off. I have removed the lights a few times and used Igor's methos (post above with link) and it is a lot easier and you don't actually remove the entire bumper from the car. It kinda flops forward and lot easier to do quickly especially compared to the FSM method.

 

But that way the whole bumper will be folding against the bottom screws only, I'd rather take the whole thing off

 

Ive personally takes dozens and dozens of bumpers off on Gs. There is nothing wrong with letting it drop down only being held on by the bottom screws. All thats happening is the bottom plastic undertray is bending, no big deal.

Ive seen igor take a bumper off in less than 5 mins. True Story.

I personally dropped a guys bumper and changed his grill and put his bumper back on in under 15 mins on friday. lol

Basically what im trying to get it is, ITS MAD EASY!

 

I always just take the bumper off.

 

Alright thanks guys. Im not afraid to take the bumper off...ive been a diy all my life and not afraid to attempt things on my own in fear of breaking it haha.
