Proper break in of a Moser 9" Like the title says. About to drive it tomorrow for the first time *fingers crossed* how do I go about breaking it in? It has 4.11's with True Trac. Thanks!

I recommend 8-10 complete heat cycles... before you start pounding on it.
A complete heat cycle consists of a 15-20 minute drive at freeway speed to saturate the heat... then let it cool down to ambient temperature. The best way to do this is to drive it to work... let it cool all day long... and then drive it home and park it until you go to work the next morning. That's 2 cycles in a day and about ten total in a weeks time. This will virtually eliminate any heat related brakedown in the lube and provide a gradual work hardening of the gear tooth surface.

I put mine up on jack stands, and went in foward gears for about 15 minutes, varying speeds. Then I went in reverse for around 5 minutes. Put it down, made a few trips up and down the road...then went to the track and beat the hell out of it with 5k clutch dumps on mickey thompson DR's! And still no whine's or howling!

The first couple of heat cycles are very important with new bearings. I usually do the first couple on stands due to how much heat a new set of bearings along with a new gear can create.

I did the stand method for about 15 minutes forward and then 5 minutes in reverse. I'm letting it cool and will take it on the highway in a few while varying the speed. Thank you to everyone for their input!
