2003 Blazer 4x4

My abs is kicking in when it shouldn't. It sounds like the left front wheel.

This happens even at very slow stops...but only sometimes.

Anybody got any ideas?

Thanks, Bob

 

Problem with the wheel speed sensor possibly.

 

can any 1 tell me when checking the abs sensor what is the resistance reading should I get, I know O.L is open loop replace, would like something around .08 be ideal .Thanks Billy.

 

often when the bearing is starting to fail it will take out the ABS sensor

If you can find an open area to weave on the road at about 50mph
you will usually hear the bearing growl that is going
If you steer to the left and you hear noise its a right bearing and vice a versa

 

Resistance is not what you're looking for, AC voltage output is what you need to check: http://ww2.justanswer.com/uploads/GM...s_bulletin.pdf

There is an inner and an outer set of ball bearings in each hub. A worn bearing will be noisy when it's loaded. When turning, one set of bearings in each hub is loaded and the other set is unloaded. Turn the opposite direction and the load transfers to the opposite set in each hub. Using a stethoscope is the best way to determine which hub is noisy.
