It means you need a wheel bearing...I have put HUNDREDS of $ into wheel bearings for my 99 alero. My mechanic advised me to disconnect the anti lock brakes...and I did! Kinda bites, but no more pesky wheel bearings to buy...No more anti lock/low trac...and it passes inspection that way.

Will a 3.4L engine out of an impala fit in a 3.4L olds alero?

yes, a 3.4 is a 3.4, you might have to swap the fuel injection unit on top of the engine to the alero's set-up so the alero's computer will work right.
