PTU fluid change frustration

Okay so I decided to make an attempt at tackling this today and was quickly thwarted.  I have an 11 PP edition and no matter how I try there isn't a straight shot to the plug in the side of the PTU.  I don't have the cooler and all of that on the '13+ but it looks to be the CAT, Oxygen sensor, and sway bar are conspiring against me in some perfect way to block any attempt at getting the socket extension in there.  It would be a straight shot if the oxygen sensor wasn't in the way.

I do remember that PP's have a nub and heat shield on the half shaft that caused some early downpipe interference...I am wondering if the exhaust is in a different place on mine?  (I know that sounds ridiculous)

I could obviously drop the CAT but that sounds like a major deal without a lift.  I'm wondering if I could disconnect the sway bar on both sides and rotate it out of the way?

Stuck...

Had to put the tire back on. May try and tackle it from under the car tomorrow...thanks for offering. I will get a better pic tomorrow if I can't figure it out.
 
Might try mine tonight. Bought fluid and pump, so my OCD will kick in most likely. Mine is non pp 2011, will take a pic and share.
 
It's back there. ..just over o2 sensor straight back almost same level as o2...large square type bit to get off...if looked at from under car it has (at least seen on couple cars now) red thread lock type stuff on it...

Yeah your going to have to get under the car. It's not hard to get to it, a couple long extensions will be helpful.

Thx...trying that now...definitely need a swivel to get back there as a straight shot doesn't work...knuckles are sore at this moment from the slip to knuckle bash...oooh

So you can't get in there straight with a non PP either?  Weird - as it sounds like some people have no problem.  Are you under the car or going in from the right front tire area?

Yes...so close to straight shot but extension set up does not make it...binds up at o2 and create bad angle

Yep same thing on mine from the right front...I still (hopefully) plan on trying it from under the car or I suppose I could attempt a swivel / extension if I can find the right lengths from the side.
 
From under car is near impossible. I have skinny arms and hands and thought I was stuck in there this morning!!! Lol...had to take my son to ortho right now but before I left 2 9" extensions, swivel, and then 2 short extensions worked to get there. Didn't get to attempt the removal yet.
 
You can't do it from under the car without some seriously small hands. It it's easiest to take it out from the wheel well. Then Crawl under to suck the oil out.
 
Just got in there straight shot...more extension than mentioned would be nice...had to start as far left of o2 as possible getting it all the way in and then sliding it over...very tight, but it is possible. Just can't start straight at it.
 
Ok...perfect setup is a 10" wobble extension off of socket to 2 6" extensions....wobble extension gives perfect amount of flexibility! !!
