When I turn to the right I get a rumbling sound from the rear of the truck but when I turn Left I get aq faint whoop whoop whoop sound from the rear of the truck >>Any Idea ??

 

Update I went outside and put my hand on the back drivers side tire and rolled it back and forward on rolling it back when it comes to lock it makes a feeling like the rims is loose ( loose lugs ) but they are not .. The other side does the same thing .. May just be the u joint and suspension .. I will check some more..
