New JKR Break-in

Happy to say that I just ordered my brand new Tank 2door JKR. So excited to see this thing move out of D1. Sold the old TJ last week after the turdy5 started leaking oil at the shafts. Auction Direct in raleigh paid well for it...

Does anyone have any advice on breaking in the gears/motor? This is the first car I've ever bought new, so not sure if it's even necessary. I've read here and there that you should change motor and tranny oil after about 5000 miles, but nothing else. How about diff oil? Do the gears need a break-in period too?

Thanks!

When you pick it up the manual outlines proper break in procedure

Still breaking in my 15 Rubicon I got in late July. ( Only got about 800 miles on it. ) Basically easy driving, no hard throttle mashes at first and just taking it on some easy road trips for the first 1000 miles. Not really rocket science. Break it in like you bought it, then wheel it like you stole it from there on out. LOL

Nope. Just make sure they are all at proper level.

2nd gear, and give it all she's got!

When in doubt, throttle out!

Drive it like you stole it!

You didn't specify that you wanted "good" or "scientifically backed" advice

LOL thought that was implied. Isn't this a place for "help"? I'm sure the motor is tested balls out for a couple cycles, so no big deal. I was more worried about pulling stuff around on the shiny new D44.

I have always understood that you should be hard on the engine and as gentle as possible on the gears. A nice balancing act. The wording from tone manual above seems to confirm this type of driving.
I have heard truck drivers say They would put it up in high gear and floor it really making the engine work. I think that is even in a post on here.
