I just swapped in my new axle shafts in my 3/4t Dana 44 but I feel as if I missed something.... Thats where the axle goes into the tube...same on both sides. But it seems odd that there is a gap here almost like it needs a seal or something...is that right? My old axles didnt have anything there either and I wasnt thinking when I did it...so its done...do I need to rip this apart again in install something? if so what? parts numbers? maybe a pic or two would work. Thanks for your help...oh is there any kinda torque specs to the brake backing plate or the 4 prong nut? I just kinda did what felt right.
