That figures. They don't care that 5th is only good with a tail wind as
long as the mpg go down eh.

Hi Jerry. You helped me out of ton of jeep problems as did all the
people here responding to this thread. In my experience my 97 sport
with 3.07 got about 20 mpg highway. My 98 sport with 3.73 (30" wheel)
gets about 15 mpg. The 3.73 gears make 1st gear at a stop light
almost unnecessary. You can take off easy from 2nd. You have to shift
so fast into second anyhow. I recently put 31" on them and didn't
notice any change in mpg. Of course the bigger tire needs the lower
gears.
I'm thinking of possibly trading for a new TJ. I'm actually torn
between the two gear ratios!! I don't do much off roading. The stuff
I do is real mild and just for fun. I'm not really into serious
upgrades and crazy rock crawling. I like the fact that I don't get
stuck in snow or mud and can go pretty much anywhere I care to.
With gas prices the way they are, I'm seriously thinking of the
smaller tire and 3.07s. I guess I'm not a true jeeper, but I still
love all things about 'em.
On the highway with the 3.07's, I had a ton of pickup in fifth. It
was great. No downshifting for passing. The jeep had a lot of punch
and just seemed quicker driving. The 3.73 make my jeep feel heavy or
sluggish. more downshifting even around town. I'm sure that's better
for off road. Just another side to it.

Re: Wrangler 3.07 vs. 3.73 Axle
Jeff, it sure reads like you're reversing how a 3.73 vs. a 3.07 would be
described by anyone I know.

Re: Wrangler 3.07 vs. 3.73 Axle
Bill-
I have an '03 TJ Sport (I6 w/30" Tires) with 3.73's. I average about
19 MPG, and have done so since new. I drive the s*it outta my rig
too, 48K miles in less than 2 yrs (purchased in 11/02).
I am like you and I don't do any really heavyduty off roading, but
when I want to find out where that logging road goes, I can without
any worries... It's my daily driver- 49 miles one way to the office
(I absolutely have to be able to get there- hence, the TJ). Although
I don't absolutely HAVE to start out in 1st gear, I just don't like to
feather the clutch that much in 2nd... I think you'll find the 3.73's
to be superior to the 3.07 for overall performance. 5th gear doesn't
have a lot of "pull" (it's not gonna snap yor head back ;-)) but it
holds it's own on hills pretty well.
My $0.02.
