Ok Bill, Now what?

Decimal points are missing in many of the tags I read as a small part of my job, yours is very likely a 2.72.

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.

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

case, which would mean 2.72 is the low range ratio in the 'case, not the final drive.

Jerry, Isn't 2.72 the gear ratio of the LO Range in the Tcase, or is that 2.62? I can't imagine 2.72 gears in the diffs, that would be very tall.

------------------------------------------------------------- Thanks! Now _that_ is the kind of response I was needing. I posted 'to' Bill because he told me where to look for the tag on the rear diff., when I posted about tires. I will do this turning thing Sat. However, right now I am gonna have to go look at the other stuff people said I was wrong about :-)

I'm going with that guess too.
