I have a ticking noise or puttering noise that sounds like an exhaust leak but a few things you should know. I can only mainly hear it when i'm rolling over 20mph. I can let off the gas and still hear it. It sounds like an exhaust leak but since i can hear it when i let off the throttle and the noise doesn't change i have to rule that out. Anyone have any idea what it could possibly be? It's an automatic, 4.0 and i do know that i need to drop my t-case a little more cause i have driveshaft rattle when i start from a stop. Any help will be appreciated, thanks in advance, Kevin

I can add some more info to see if anyone has had similar problems. When i am going 20-40mph I can put it in neutral and the "putting" is still there. No matter how fast above 20 the putt-putt sound does not change speed between the putt's. I can sit in the driveway and rev and hear it faintly but not as defined as when i'm rolling on the road. If i push the brakes there is no changein sound. If I turn it's still there. I have not noticed a change in power but i just feel like it's running on 5 cylinders or something. The noise is a distingtive Tff-Tff-Tff-Tff if that helps anyone diagnose. Please somebody know what i'm talking about please it's annoying me not knowing what it is.

Are you sure it's an engine noise? If it's a pump (I'm thinking fuel-pickup) then the noise will always remain the same at any speed/gear... unless I'm mistaken (and if I am I'm sure someone here will advise me). I occasionally get an even-tempo-ticking when I get low on fuel, no matter the speed, rpm, etc. So before you get out in the middle of BFE it might be wise to check that.
