Rebuilding my Rockwell front drive axale

Having the shop rebuild my power divider, I never take my truck to have it worked on I have a service truck and usually do the work my self in a dirt lot but this is no job for the dirt, anyways to get the whole remanufactured rebuild is only $200 more than just the power divider, my question is what is actually done to reman a drive axle set, do they actually replace gears with new? And just keep the base as in do they weld on new ring gears or clean them up, I want this to be done right.

 

It comes with a one year warranty and is remanufactured 100 miles from me, thx for responding

 

Thanks I'll make sure about that, I'm also going to make sure I get to. Look over all the parts before the Install, should have the parts Monday afternoon and install tuesday

 

It's going to run me about 2500 all together parts ran about 1800
