I have to replace my front rotors. I have a 2002 V6 extended cab 2x4 styleside, with 85,000 miles. Are these rotors hard to replace? Went to local 'Autozone' and was told that I needed to buy $60 rotors that have bearings in them. I have never had to deal with bearings. This is my first truck. I have done brake jobs before but the rotors just came on and off, no bearings. I haven't been able to inspect them yet as where I live now I am not allowed to do vehicle maintenence in the apt. parking lot.
