So i have a 2018 JLU sport manual transmission. In the frot i have a Dana M186 and rear Dana M220. I want to re-gear to 4.88. I have about 21,000 miles on the vehicle. Can i use dana 30/44 ring and pinion or do i have to use specific to the m186 and m220? Also should i replace bearings and shims? Or leave as is? And what brand, and install kit should i get?
