That's funny, on my way home tonight I was thinking you might not have left enough slack in the wires. Glad you fixed it.

The squeaking sound is indicative of a bad bearing. That's nothing you did, it just a manufacturing issue. Sometimes you can fix it with a tiny drop of motor oil placed on the shaft where it enters the housing.

And by "winding up the motors" I meant hooking them up to the battery right after soldering. Typically you'll want to wait 15-20 seconds after soldering to let the internal heat dissipate before running them full speed. That's all.
