i have recently come across a rear xj dana 44 with 3.54 gears, the same as my front axle. i am trying to decide it is would be better to keep the rear and regear it to 4.10. i already have a front and rear (30/35) combo that is 4.10. but i was really leaning twards going full width and going to 4.56 or better. if i was to seel the combo what would a good asking price be for the front 30 and rear 44?
