Based on this latest info, it sounds like diff fluid is leaking when the engine tips to the left (which is shouldn't!) That brings me back to that oring that you originally suspected.

I haven't done it on an E53, but on my E83, it's possible to remove the front diff without dropping the subframe. I'd be doing that to inspect that oring for damage.

The fact it's not leaking after replacing the motor mount means nothing.

Thank you for your reply
There is no way you canít avoid dropping the subframe when you are dealing with anything connected to the x5 oil pan
On the X5 to anyone need to work on doing the work the driverside got short shaft that goes into front diff and does not go into the oil pan however the front diff passenger side has an extended small shaft that has a sleeve and o ring that attach to the oil pan. The driver side got long shaft that goes through the oil pan and connected to the other side to the front diff.
The cam showed the leak coming from the small shaft on the front diff driver side that has the sleeves and the o ring
ďIn my caseĒ when I was moving around trying to see how the leak coming out the leak stopped.
The car had over 135,000 miles and believe somewhat I did over pulled the engine up the first time I worked on the shaft while the shaft still connected or I damaged the morning by trying to lower the engine. The reason for that I had very hard time lowering the engine to the mount and at the end I had to remove them totally and installing them to the engine then lowering the engine to the frame. After few pushing with my portable pressure tube I managed to install the mount to the frame
In my case as I stated my kids play hard with the cars and they donít tell me in details what they did and I canít say for sure why the leak stopped Iíll leave it as is thanking everyone for their extremely appreciated inputs and questions god bless

If you remove the inner bolt from the lateral control arm, you can swing the hub assy's enough to disengage the front axles from the diff. You don't have to remove them completely. Then disconnect the front driveshaft, remove 4 bolts, and the diff can be lowered to the ground (this again is on the X3, but the X5 is built VERY similarly).

Best of luck to you.

AM.
