It's not about doing trails in reverse, its about torque peaks when backing in reverse, even though rare. For example, backing uphill whilst pulling someone else out. I guess the u-joints or shafts would probably fail first, but the R and P would see a lot of stress in a situation like that. Just because an axles does almost all of it's work in one direction doesn't mean it won't see greater torque loads in the rare opposite direction.

In reality, it may not be a problem for people. But surely the R and P would see it's greatest stresses in such an uphill backing, towing situation.
When they introduced the 4:88 gears for the low and high pinion Dana 30's, the internet logic said that because the pinion was so tiny that they would explode if you even got them near a trail.

The theory was sound in that a smaller pinion is or has the potential to be weaker, actual practice has proven that to not be an issue.

You are correct in that it will be weaker driven on the coast side backing up hills. You are incorrect in that it will likely ever be an issue.

But it would make my life easier if someone had already done this swap and knows what the dimensions are. My jeep is a 4.0 5 speed NV 3550 tranny and NV 231 T.C.
You should measure on your specific setup.

There are too many variables to ask someone else about this.
