FYI, the procedure is practically the same for the 2010 Coupe:

Looks like it might be the front differential. The news keeps getting worse. The crack is in front of the Tranny pan and behind the oil pan.

Can anyone verify from the video? If it is the front differential looks like I'll have to take the engine out.

Ouch! If it is the front differential it is not going to be a easy repair... Sorry this happened but definitely see if you have a claim against the city/DOT...

Yep I plan on making a claim, I took some pictures of the bump. I slid on some ice since they didn't end up salting the road and i hit the pothole at around 10 mph and it instantly cracked my differential. Have you taken a look at the videos? I'm pretty sure its the front differential, the oil that leaked out seem to be gear oil.

I did look at the video. It does appear to be the front drive assembly. Others who are more familiar with the AWD system, hopefully, will be able to offer advice/options/replacement tips and tricks/etc.

Good luck to you!

Thank you! In the meantime i'll let it sit in the garage and give a few calls. Is it common for the front differential to snap like that over a pothole?

Probably not common but anything is possible. Likely you hit the pothole at just the wrong angle/speed for the suspension to absorb the impact. The ice surely did not help.
You know the old saying: sh*t happens..

Iím sorry I canít squeeze my chunky azz under my car enough to look or take pics. I may have time tomorrow to put it on a lift and take pics for you, for comparison. Iíve only seen differentials or transfer cases break like that because of some underlying issue, like bad u joints, no fluid in the unit or of course abuse, which doesnít sound like the case here. Like the other guy said, probably just the right parameters for this to happen

You're fine! I really appreciate how much help you guys are giving me! And there was fluid inside and it seems the ujoints are fine from what I can tell. I'll have my buddy with an engine lift stop by and might work on it together with him to save money. I will make a claim against the city for the pothole though.

I'm buying a new differential and will be putting up pictures of me changing it out with my friend! Hopefully it all goes well!

This is a real bummer!

Just a thought, actually a side note..... if you had been considering a gear ratio change, now's the time to do it. Used front diff can be acquired for $200-$400. There's a thread that discusses this.

I found a few threads about swapping out the front diff. These might be a good read for you (OP).....

What are the advantages of a gear ratio change? Also thank you for the links!

You can change the gearing from 3.357 to 3.69. I have diffs, including a rear VLSD diff from a 370Z and a front diff from an 08 G35x, awaiting install. You can tell the older Gís have more romp off the line, while the 37ís have a more practical gear ratio probably because of fuel mileage. If you change the ratio in an X, front and rear gear ratio must match. If you are just looking to replace whatís broke, make sure your donor front diff comes from a car with the same axle code as your car, and youíll keep the same gear ratio. Axle code is found on driverís door sticker
