Front Differential Swap

[Justheman80]

I have a 2014 Sierra 1500.  What years of front diffs would swap to my truck?

 

Specifically would the 1999-2006 and or 2007-2013,  1500 trucks swap in?  Have anyone done this themselves?

 

Thanks,

Needs to be from 2014-2018 trucks. The frames aren't the same on the older trucks.

The case and housing are the exact same from 07-18 and 19 LD but the axle shafts and 4x4 actuator are different from 07-13 and then 14-18 and 19 LD.

 

So your best bet is a 14-18 or 19 LD front axle.

Would the stub shaft with actuator swap from my current truck, to an older housing?  
 

I have found a cheap 2003  3.73 front diff and would re-gear the rear to match.

Well, 2003 isn't in the range of 07-18 so no, a 2003 diff wouldn't work.  99-06 case is quite different.  

 

Ideally, you need a 14-18 or 19 LD diff.  You "might" be able to make a 07-13 diff work by swapping the actuator, possibly the shafts.
