Re: Ok Bill, Now what?
 

I'm not Bill, but I 'can' tell you an easy way to check the gear ratio
if you want.

You block the wheels and put it in neutral. You then jack up one wheel
and make a chalk mark on it and on the driveshaft.

You then spin the tire two times while counting the number of
revolutions of the driveshaft.

If you have 2.72's the driveshaft will almost turn 2 and 3/4 turns.
Mine turned a bit more than 3 and 1/4 turns so I have 3.31 gears.

>> Ok Jerry, now then. Is a 2.72 a good thing, or a bad thing?

I'm not Jerry... but I play him on TV.

2.72 is the highest (numerically low) stock gear setup for a CJ, and won't
do you any favors off-road. On the road.... 2.73 will let you do 80 in your
CJ, but off-road it leaves a lot to be desired. I ran those gears in my CJ
off road for one summer before deciding I needed to switch for lower
(numerically higher) gears.

But if you want an easy driving, low revving daily driver they aren't so
bad.

Sounds to me he's describing the transfer case..."Big round riveted
> 'thing' on it from Syracuse New York." Which would make it a New Process
case, which would mean 2.72 is the low range ratio in the 'case, not the
final drive.
