^^^^^ You’re sounding kinda like Shiner. You’re making a claim without any kind of logical explanation. If you’re pulling a heavy trailer out of a bog in 1st gear with the transfer case in 4 low and worried about u joints .... yes the 4.30 gears will be less likely to break a u joint than 3.31. Although if the trailer doesn’t come and your tires don’t spin the strain on the joint will be the same in both cases.
Edit: What do you mean by saying "spinning 4.30s is "easier" than spinning 3.31s"
Easier on fuel?
Easier to get the trailer moving from a stop in first gear?
Easier on over drive clutches pulling a heavy trailer up a hill at 60 mph?
Easier on the torque converter at 65 mph with a trailer in tow?
What do you men by easier and under what circumstance is this going to come into play?
