What's next?

So I just took the jeep to work 2 things I noticed was once we hit the steepest of the hill the thing started to clunk and oil levels went down drastically. Do I need to add oil? Second, the it has no bounce on suspension I looked at the leafs and they appear over loaded. What should I look at? I'm prob want to leave stock wheels anyway. Also my muffler is hanging off after I made it up.

That was the most focused ride home. Checked oil level before starting it was "safe" turned on gauge went from 10 to 0 to 45. On the drive home pressure averaged 45 to 40. However when I would slow down or stop it dropped to 10 with a clicking noise. When I got home I let it idle for a bit it remained at 10 w clicking noise. Pls some input !
