2002 Montero ABS Cycles PLEASE HELP!!
 

Hello all. I have a 2002 Montero Limited, have owned it since new. We are having a problem with the ABS system. Every 5 seconds, the pump cycles. You can hear 5 "ticks" when the pump cycles. Sometimes the noise is a loud screetch, sounds like there is a big rat in the car. Can anyone help me diagnose this problem? Thank you for your help. This noise is freaking driving me crazy! Thanks again.
