i want to know why....how come ttb dana44 only can accpet up to 33" tires while 8.8 rear can control up to 37"???..(i am deaf and lot of learing about bronco)if yall think i ask stupid question..sorry :thumbup
Your question is basically just leading to a ton of opinion.
you could go and put 40's on these axles if you left them open and drove around malls all the time.
use a bronco hard out on trails and I'd say the limits are usually around 35's for both axles. This opinion of mine comes from 1) experience owning
2) seeing what others' experience has been (good and bad)
3) knowing that stock D44 axleshafts and joints usually can just handle 35's with open front, careful wheeling, and stock motor
4) 8.8 rear has a tube to diff issue so spinning the tube or bending it is what I've seen mostly with this axle used offroad. This can be helped with a truss and weld. If equipped with a limited slip carrier, so much material is removed for accessing the clutch plates, the carrier itself becomes a weak link. Use a detroit or something and problem solved there.
