Well, got the 4.10s and Eaton installed last monday. I've gone almost 100 miles grandma style like the break-in period suggests.
It sucks, I wanna mash the gas sooooo bad
This is what the instructions for the precision gears reads...

"Bring axle to normal operating temp by driving the vehicle(unloaded) for approx. 15 to 20 miles...Let the axle assembly cool completely..."
Did that already...drove it 15 miles in 35mph stop and go traffic, then let her sleep for the night...

"For the next 200 miles of operation, drive gently, without any heavy loads..."
I'm gettin there

"If trailer towing is intended, an additional cycle of 200 to 300 miles break-in is required without the trailer. This is important!"
So does that mean if I don't do any towing (which I don't...ever) I can mash the gas after 200 chill miles?

The reason I ask is b/c of the last part which comes right after the last quote I made...
"To properly break-in a new gear set, a minimum of 500 miles of driving is essential before constant towing."
So should I do the 500 just to be safe?
Damn, I'll probably just do the 500
