Which locker would be the easiest to install in the front axle of a 2014 Tacoma?

 

who is doing the work? even i was able to install front and rear aussies in my 81, pretty easy i just followed a write up i found on gearinstalls.com
personally if you have the $$ i would not put anything up front but a selectable locker

 

As far as install goes, they are all pretty similar. The most crucial part is setting up the gear pattern again when you re assemble it.
