I'm planning on upgrading to chromoly shafts, but it will be a few months between swapping the front and the rear's.

Which should I do first? Front or rear? I will be in Moab in three weeks and will do the other end when I return before the summer.

 

Rears- you're more likely to bend a flange and cause issues. You can drive without the front shafts of things go wrong.

 

also rears are much easier to change.

 

I would get rears first but I would also look around for some used stock take offs for the front so you have spares when in moab. When you get back pick up chromoly fronts with spicer sealed ujoints and full circle clips. Highly recommend ten factory
