My rear axle is leaking at the bottom of where the 3rd and the pumpkin come together. I checked the bolts and the bottom 2 were loose so i tightened them back up but is there a gasket or anything else that could have made it start leaking? I had the fluid changed back there about 6k miles ago. Anyone think it could have just come loose from the work?

 

The fluid getting changed shouldn't have make your diff leak. I know that there is a gasket specifically for the pumpkin, but when I was changing mine I couldn't get a hold of one so I just ended up using some gasket maker. It's been nearly half a year with no signs of leakage. Of course, to take it apart just to change a gasket is a lot of work, but not difficult. If you don't mind getting dirty and have most of a day to kill depending on your skill, you can replace it pretty easily.
