        So should I forget about ever using the spare?  All it does is
squeal when I drive.  Right now it's ok because I have four normal tires on,
but you're saying that even though there doesn't seem to be anything wrong,
I am actually stressing my Drivetrain really bad with bald fronts.  Does
this sound right?  What will it break?  Rear diff, front tranny, drive
shaft, trans axle?  Just want to prepare myself for the bill.
