Just noticed this leak yesterday. Never leaked there before. Checked the gear oil. While down a little bit, it only took about a cup of gear oil to bring it back up to mid point on the dipstick. That entire side of the axle seems a bit "wet" from oil, top to bottom. Other side of front axle is dry and clean. First time I removed the dipstick, there was quite a bit of positive pressure. So, I wonder what could be the cause. Any ideas? Thanks
