I am still thinking about that one... Its a bit confusing, but yes I do
want a higher numeric value. BTW, I am still learning all the Jeep and 4x4

Looks like I will just have to save up while trying to use all the tread on
my current tyres. Once that is done, I can change both tyres and gears at
the same time. I know that is going to cost me some pretty penny, but
would be fun. Also by that stage, I should develop enough experience
off-roading to need bigger tyres, higher suspension and higher numeric
value gears.

Thanks for that. So what you are saying is that I don't need to worry
about the tranny went as it closes under water. I already have a high
level on my front axle. That leaves me with transfer case and rear axle.
I need to spend some more time under the TJ to find out where they are. Do
you happen to know the approximate location and sizes? Also whats the best
way of putting a downward bend on the a/c went as highway winds tend to
push water back in under certain conditions (like about 80kmph speeds).

When you say torch, some will think you are going to burn a new vent hole
yourself (with an acetylene torch), or keep your coffee hot. Having
traveled "down under" a bit, I recon you're talking about a flashlight.

This is really a basic mechanics principle, not a Jeep thing. Look at it
from the perspective of the input shaft (engine et al), if the input turns
3.07 times for each revolution of the output, then you have X amount of work
being done. If you want to reduce the amount of work, then you wou8ld make
the engine turn more times, but with less effort. If you selected a gear
that allowed 4.10 turns of the input for each turn of the output, then each
turn of the engine would be easier, but you would go slower.

The trans has selectable gear ratios. 1st gear is about 4.2 to 1 (expressed
as 4.2:1), but 5th has a much higher ratio of .073:1, or there about. In 1st
gear, you have loads of power (relatively speaking), but in 5th you have
very little power reserve. The lower gears have a higher numerical value
than the high gears. The diff is pretty much the samd thing, but you can't
change the selection anywhere near as often.

Correct, you don't need to worry about the trans. The tcase and the rear
diff vent tubes look exactly like the front diff vent tube that you already
found. The tcase tube is attached to the firewall near the battery - maybe
closer to the engine than the battery, but on that side. The rear diff vent
tube goes up inside the fender, it comes off of the axle itself very similar
to the front.

At those speeds, there is positive pressure on the end of the vent tubes,
water mist from highway travel is not going to get in. The problem water is
that which can keep a fish happy.
