Hey. I recently put new rims and 32" Falken Wildpeak AT3W on. As expected, I cant hold 8th as well and cant start off in 2nd as easily. Considering changing from the stock 3.09 to 3.45 from the Jeep WK2 or 3.45s from an 11-13 Durango RT. Anyone on this forum swapped out the carrier assembly on a 3rd gen yet? I have AWD, from my research the front should be pretty straightforward.

 

Don't install used parts. Buy new gears, and re-gear both ends at the same time.
