Gear beak in?

I finally took the dive and had 4.88s installed in my TJ. I've tried to
figure out the best break-in procedure, but everyone seems to have their own
opinion... and you know what they say about opinions...

So, what do you all recommend? Any of this based on actual experience?
What works best? So far the only common factor is a 500 mile fluid change
(some do it sooner, but still do it again at 500 miles).

Thanks!

I try for two hundred miles before I get on it, or hook up a
trailer.

The way my shop has stated I should go is to:

1. Only drive 10 miles or less at a time and stop for 30 minutes after each
10 mile segment.
2. Do not drive over 50 mph.
3. Bring back to shop at 500 miles for fluid change/pattern check.

This 10 mile increment and under 50 mph wouldn't be so bad if I didn't have
to do it for 500 miles!

Hi Eric,
I'm thinking you told them you only have time for fifty miles, so
they went a long. I want it at full operating temperature, so pick a
town a hundred miles away and drive to it. Or when it begins to sing,
you'll be hearing I TOLD YA SO! ;-)

So what break-in procedure does the factory say for us to use on our new
Jeeps that barely get driven before they get delivered to the customer?

The manufacturers say they're down the thirty minute runtime on a
wheel dynamometer tests, because their parts are initially finely honed.

Bill,

You hear that service parts, that you buy from a dealership or aftermarket
supplier, are equal to or better than OEM parts. Whom is one to believe?

You also hear about "lemons", which could be a vehicle that was put together
wrong, or perhaps broken in wrong. Who knows? It does appear that the
"fine honing" is not 100% reliable.

I picked up my Honda Civic at the dealership, and drove it 800 miles in a
couple of days. It had been driven before that 200 miles from the
dealership in Colorado Springs to Fort Collins. I am sure that it was
driven at 75 mph, the speed limit on that stretch of I-25. I guess I got
lucky, or the parts were honed like you say.

All I can tell you is installers stick to a break-in time. And I
can tell you of my Son's Brother-in-law had Jack Powell Chrysler of
Escondido, California change the ratio of his new Dodge. They didn't
have the time to break it in before a trip to Ocotillo Wells, toting his
Jeep inside his Toy Hauler: http://www.billhughes.com/jeeptrailer.jpg
Climbing our low road around Julian to Lake Henshaw it exploded taking
his ABS out too, at about hundred and twenty miles. The Stealership
found a way not to cover it.
Where do you think factory seconds go?
