I started to replace the wheel bearings, but noticed oil and dirt caked on the side of the Front Differential below the left bearing. When I pushed up on the axle where it attaches to the diff, I noticed more play than I expected. Have I found the bad bearing?

I'm going to drain and replace the oil in the diff, and see if that has any effect on the noise. Has anyone had a lot of womp womp noise (40-50 mph is really loud), and fixed it by changing the front differential?

Is the oil leak unusual?

Should I be able to see play in the connection between the axle and the diff?

Thanks!
