Differential leak?

I have an 05 tj and my front and rear diffs seem to be leaking where the drive shaft goes in. This looks like it should be an easy fix but I'm not a mechanic so I'm not sure. I'm sure yall have seen this before so someone tell me whats up.

-Well I tried to post a pic from the desktop and it says enter the pics url so i uploaded it to facebook and posted the link but the pic isn't working. I would delete the post cause its pretty useless without the picture but I can't find out how to delete it. Sorry guys!

Your pinion seals are leaking. Sometimes just changing your axle oil fixes the problem.

They are easy to replace.

For a Dana 30 front axle you need a new seal and locknut. The locknut is considered one time use. Just pull off the driveshaft, replace the seal, and reinstall with a new locknut, torque to 210 ft/lbs. Make sure you clean everything up good and you might as well check the axle breathers while you are working on it. The hardest part is 210 ft/lbs.

Not sure about Dana 44's and 35's.

210 sounds like a lot more than has been recommended in other threads IIRC. My recollection was 160-180.

Agree as to first changing the fluid. A little seep that just darkens the diff doesn't bother me much. I'll pay more attention if I see actual drips off diff.
