this may seem like a stupid question but i dont have the time to check this out until sunday (my only day off from 2 jobs). is there a simple way to tell without removing the wheels to know if my front rotors are just the disc or the disc/hub? it is a 1995 Tahoe 5.7 LT 2wd. i know i should just pull a wheel but i honestly dont have much time til sunday and im trying to get the parts ahead of time.
