Re: Re: Does GM 3.73 gears fit a 1993 jeep yj?

Sno Ball,

Mike and Bill have been here a LOT longer than you and have both forgotten
more that you will ever know. Let's not forget you discovered this group
while Usenet-stalking Mike, because he called you on your -------- in
another group. Over in alt.trucks.ford you are almost universally disdained
for the idiotic advice you provide.

If you can, provide advice without the crap. Until you do, consider yourself
plonked.

Is your object to install lower gears than you currently have? You
didn't say what combination you are starting out with. With 35s, 3.73s
are not low enough for ideal offroad driving. You will want 4.56s. You
also did not state what differentials you are running. This may limit
your gearing choices. Buy the gears specific to those differentials.

Sticking to the math:

If you started off with 3.07 and 28 inches is the stock tire size:
3.07*35/28 = 3.84. It is recommended to go one gearset numerically
higher, 4.10.

If you started off with 3.73 and 28 inch tires: 3.73*35/28 = 4.66.
Next numerically higher, 4.88, this is as low as you can go with stock
axles.

You know weather you have been here 6 month or 6 years does not make
bad advise good and I guess you are in the pond with them too. There
is a right way and wrong way to do things and you guys pick the wrong
way. Your BS dopes not defy the logic or physics involved here and
even if they are still here after 20 years they are still wrong and
you too. Truth is not based on how long you have been selling your BS
but rather the facts o9f the matter but fact and physics ellude you
guys so of course you back the looser. ALso as far as being here to
attack Mike, it is not personal and I did not fire the first volley.
It is the crap he ------s that I attack and will continue to do so
when he does it. If he makes factly posts I will not attack him but
when he sets himself up as a expert (when he is not) he should expect
the flack.He has a serious ego problem as shown in his sig. You know I
have OWNED 11 4x4's in close to 40 years and currently own 3. Most of
them were bought new too and I even have a 28 year old jeep truck (I
have owned it for 22 years now) that still runs and it is 100% stock
with no engine, tranny or Tcase failures) and it pushed snow hard for
many years too which is harder on a vehicle than off roading because
of drive train loading. If I had used Mike logic on mods and
operational practices it would have died long ago. Some of you guys do
not want real answers, you just want BS answers to make your ego feel
ok.
