Re: Can someone tell me what this is?
Changing the rear dif fluid on the 08 CRD I noticed the tubing to the vent was broken. Got some tubing to replace it and decided to check the vent for obstructions. Turns out it wasn't drilled out all the way so until the tube broke the dif wasn't being vented properly. Something to keep in mind though I haven't heard of this before. Checked the front for comparison and it was clear, noticeably drilled deeper for the inlet/outlet to meet.
