Blown differential
Initially, I just thought the noise that was coming underneath the car was from a big size pebble stuck on my slicks and was rubbing the plastic wheel liners. Finally got around to removing the wheels to investigate and this is what I see.

I don't see anything wrong with the rear axle just your diff fluid all over the place. Looks like a seal between the drive shaft and rear end blew?

Maybe just overheating/excessive temperatures during a track session?
Hopefully it isn't serious.

I sent photos to my mechanic and he also thinks the Rear Axle is toast since it was making a rubbing noise while I was driving around town. He thinks the CV Joint needs to be rebuilt at best. Well, we all know Stealerships replace parts and not rebuild them. I'm not trying to skirt the dealership because I'm heavily modded and I'm afraid it be denied warranty. There has be to direct correlation with the part damage, and the mods installed to be denied warranty. Example, above normal horsepower or torque brought by a "Tune" equals a Blown Axle? Nope! So no connection between the two so I'm not afraid of warranty being denied. It's how everyone should rationalize warranty.

CV Boot is just a piece of rubber. Guess you meant CV joint.

A torn boot will throw grease.

That looks more like CV Joint grease more than diff fluid.

Yep, I just had this done - 2 weeks before my warranty expired!

This is simply grease and not differential fluid. Your diff is fine.
There is thick grease inside the black CV boot that lubricates ball bearings, etc. Looks like that clamp maybe loosened and grease escaped under the boot. You can simply reboot the CV axle and put new packing grease, but since its under warranty just throw in a new axle. Not hard to do.

Definitely an axle problem, not the differential. The CV joint boot failed (or the CV joint failed and tore the boot). That's axle grease not differential oil, plus it's coming out around the CV boot. Differential oil would come out between the diff and the axle, so further inbound.
Regardless, love the Forgelines! |

I find it strange that not a lot people know about the Forgeline brand in this BMW forum. Plenty of people will actually chose the HRE etc, etc. over it. Shown in the photo is my square 18x10 Et 27 Forgeline GTD1. Thanks!

Thats a sweet looking ride! Wonder if those wheels in 19" will work on an M2c.

It should. The GS1R are forged, made to order wheels. It means they can make it in 18" or 19's, accommodate BBK with custom offset to fit any car. Thanks
