It's probably having to carry too much WTF. Get rid of some of the WTF and the jeep will be lighter.
The air escaping sound is a clue that you most likely have a big vacuum leak.
There are a couple of ways to find it...
1. Listen for the source of the sound
2. Start pinching vac hoses until it goes away
3. Use the propane gas trick
Have you noticed a loss of braking power? If so, it could be the brake booster.
