Yes it can and its got a torx bolt holding it in and then a few brackets on the wire up to a simple connector on the frame about 1.5' long from the sensor. Unless the wire is cut doubt thats it - remove and turn the wheel/hub and look in and see if the cogs are broken in the hub.

hey, got two problems with a 2001 jimmy. Problem (1)
: Last year about the this time, I had problems with my heater....no heat. Through you guys I found an easy fix with radiator cleaner...but oops, I don't think i flushed the radiator good enough now it sounds like i have a engine full of canaries until the engine warms up for about 20 minutes. Is there anything I can do
 
Problem (2) my brake warning lights stay on and the car sort of has a bounce and a slight erk in the seering wheel... whats that about?

If the heater core gurggles it needs to be flushed and you can do that by buying a 3' length of 5/8 and 3/4 heater hose, cover distributer with plastic, and remove the 2 hoses at firewall and flush with a garden hose both ways till runs freely. Hang the ends over the fender and simply hold the garden hose to the heater hose while on with your hand wrapped around so not high pressure to blow the heater core.
That is the red brake warning light I guess and probably the emergency brake pedal is not fully releasing so see if their is something hanging up above the handle. If ABS post back.

It looks replaceable, but where Can I buy one. I think I pulled wire too hard while doing some axle work.

At the dealer. Held in by 2 torx bolts and about 2 feet up theres a connector on the frame that unclips but has a plastic pin holding it to the frame so pop it out. Comes with the new hub also if thats needed.

2001 BLAZER ABS by diablo3

THE BRAKE PEDAL ON MY BLAZER PUSHES BACK TO ME WHEN I APLPY
PRESSURE AT 10 MPH OR LOWER AND MAKES SORT OF A GROANING NOISE. NO PROBLEM AT HIGHER SPEEDS I CALLED GM AND THEY TOLD ME IT'S PROBALLY A WHEEL SPEED SENSOR TO HAVE THEM CHECKED AND CLEANED OFF AND THAT WILL SOLVE THE PROBLEM. I WENT TO A DEALERSHIP AND THEY TELL ME IT'S THE ABS AND THEY WILL HAVE TO REPLACE IT. I HAVE AN APPOINTMENT FRIDAY TO HAVE THEM CHECK IT. IS THE DEALER TRYING TO RIP ME OFF ASSUMING THAT IT'S THE ABS WITHOUT CHECKING IT YET. I'M SURE A WHELL SPEED SENSOR CLEANING OR REPLACEMENT IS A LOT CHEAPER THAN REPLACING THE ABS SYSTEM. THANKS
