I have this howling sound almost like the rear diff is howling at low speed. Only when pressing the gas and if I let off I stops. It's been there since I got the truck but not sure if its gotten louder or if its just me thinking it did. I need to take it to the shop anyways so il have then look at that too. Just wondering if anyone else has the same sounds?

nope but that description fits the rear end lash settings 100%
it will just keep getting louder and louder until you get it fixed

Have it ckd my folks bought a 2006 f150 super crew and before it got to 5 k it blew the rear end out. Evidently it left the factory with out and diff fluid.

my money is still on the rear end !
Got the call from the dealership and was told the sounds coming from the transfer case. Won't know anything exactly until Monday.

Quick side note: 2013 explorers are pretty nice rigs. ( my loaner )

So the update is Ford looked at the issue and decided to repair instead of place the transfer case. Clutches and bearings were going out but as far as that everything is fine. Parts should be here tomorrow ( Monday ) and I should have my truck back this week. Just to give peeps a heads up if if you hear a howling sound once you get a little more miles on your trucks.

Oh ok almost three weeks and the dealership fixes the transfer case..... But wait oh road test still has a sound ( probably the same sound since the beginning ) no their saying that sounds from the rear diff. I was thinking it was that since the beginning. Well hopefully I get it back in the next day or two. I really am going through boost withdrawals.
