gear break-in

[ducky]

So exotic kustoms replaced my ring and pinion for free. They said they would do the gear break in routine, but should I go ahead and do it as well once I pick up the truck tomorrow? Which is like; drive 15-20min easy accleration.. Stop, let cool down.. Repeat..

Only thing that sucks is like its an 45-hour back to my house.. So that might take a while. Should I replace the gear oil after the first 500 miles as well? The yukon gear instructions say too... but they are referring to vehicles that tow..

anyone?

I would say drive the trip easy, let it cool and your good to go. It depends on the fluid your running, if your just running just a mineral base with the friction modifier I would change it after a few hundred miles. If you have a good synthetic, leave it. I run royal purple, 75-90, just my .02

If you run synthetic oil in an Auburn you will void the warranty.

My Auburn manual specifically says do not run synthetic.

Certain diffs call for certain fluids. I would go with what the manufacturer recommends. But yeah, you must do the proper heat cycles with the rearend so that you set it correctly. And if it says to change the fluid, do it. Personally, I would. Gear oil isn't that expensive...

The only thing I'm worried about is putting the cover backon. I usually have bad luck and it wont seal, and itll start leaking

I just use black rtv, I dont even use a gasket. Just clean both surfaces, small bead of rtv aroun all the holes and between, torque it down, let it sit for an hour or so, fill and go. done it a bunch and havent had any issues. again my .02
