Hello all, question about a sound I hear when driving. I think its normal but have not driven enough jeeps to confirm.
its a 5 speed and when driving, when I let off the gas and coast (in gear) I hear a loud roar of what sounds like the drive shaft spinning and as soon as I give it gas, it goes away (or its much less noisy). left off the gas and back it comes , 100% throttle related.
my jeep does not have any rear carpeting so I think its amplifying the noises I think I hears when test driving other jeeps but they were quieter (had carpet).

just want to be sure nothing is wrong with it.. I am ok with the noise, just want to be sure its ok.

maybe a better way to describe the noise is it sounds like a truck with mud tires..that sounds.
 
That's probably normal if you've removed all the carpeting and what not. Usually if a driveshaft is bad it will give off vibrations, and if your diff is going bad it's usually more of a whine than a roar.

thanks Chris, yeah, I would say its more of a roar sound vs whine..
 
Noise when letting off the gas that is not there under power. Kinda sounds like differential.
