Rear diff swap
I have a 2003 dodge ram 1500 4x4, I need a whole new axle housing so I went to a junk yard and bought a whole assembled differential everything is all good it will mount into the truck. Two problems tho. One is that the only difference in the two axles is the caliper brackets. I need to know if this is a big deal or not, secondly if this difference in caliper brackets is okay I still need to know what year truck this axle came off so I can get pads and rotors. The serial number on the differntial is 53069431ab. How y'all can help thanks!
