As long as you used the same shims and they were installed correctly, I wouldn't worry about breaking them in.

But if you replaced your bearings, I wouldn't spin them too high. Keep your speed under 55 or so for a couple days.

You didn't forget to add friction modifier, right?

I just drove mine nicely for a few days to settle. Otherwise you really don't have to break them in. If there are no noises now, your perfectly set up.

Give 'em 100 miles with no hard launches and no burnouts. After that, you'll know if something's wrong.

I agree with Mo dingo.

Heat cycling is the only break in I've ever really heard of. Drive them a little and let them cool -- do this a few times. After that, they're good to go!

Some people don't even wait for that!

Since they are used gears, they have already been "broken in". I wouldn't worry too much about it.

They probably didn't change the shims and just swapped the gears. Take it to a shop before you break a gear.
