I am considering on this winter putting a set of 4.10 front and rear in my 04.5 3500 does anybody have any tips or things I need to be careful with on disassembly and assembly?? I have noticed the front axle nuts are pretty rusted ok to put a little heat on them??I think it is pretty sad I can replace the front and rear ring and pinion gears all new seals and bearings for less than going down to 33's for next pulling season??!!I am looking at 4wheelparts for the gear set due to lifetime warranty. does anyone know of a better place to buy the gears??
