Do you have to swap both the front and back together? I put 305's on and can tell I need 4.10's now. Any help would be appreciated.

 

you hafta to both and your lookin at about $1100

 

You could always remove the front drive shaft and do the rear now. Then when you can save your money again, do the front. I hardly ever use my 4x4 (maybe once a year) so this is my plan.

$660 is what I was quoted for labor here and I'm buying the ring & pinions and master overhaul kit myself ($502).
