ABS Sensor? 02 Tahoe?

Hey bunt,

Ya know what, the guy with the scanner is right too, but you would want to varify with the meter. And the fella that mentioned the bearings is also correct, if the bearings are that sloppy the truck would be pretty hard to handle. That pic of your rotor didn't look too good for only 20k miles. You should look at your calipers. Gets pricey duddn't it... After you change the calipers you'll need to bleed the system. I'm thinking one of these guys can explain that one better than me. I've only done it once on anti-locks, and that was on a 1 ton ford van. It's important you get it right.

My head is spinning! lol.

I'm, technical, but not this technical. haha.

I did pull the sensor from the hub when I did the rotors and like I said..to my eyes, fine? When it comes to checking the voltage and all that...thats when I need to call in an expert.

With it being a breaking issue, hauling my prize boat, and of course the kids...and wife, I figure its something that I best just let the 'experts' do it.

She's going into the dealer for diagnosis. Hopefully the estimate isn't too bad (I am unemployed) and then I can decide from there if I just let them fix it or myself.

Thanks for all the help guys! I really appreciate it! I will report back as to what the dealer says.

You would bleed a brake system the same way after replacing the calipers whether it had ABS or not.

If the outside of the rotor is shiny than the caliper is working. It is very common for the insides of the rotors to rust up on those trucks.

It doesn't take much play in a wheel bearing for the air gap between the sensor and the exciter ring to become excessive. Many times when the vehicles are test driven there is no handling issues. Just a little howl sometimes. In fact if you are noticing a difference in how the vehicle handles and the wheel bearing is the cause than you have just ignored months of warning signs including the bearing sounding like a freight train.

Just got home from the Dealer.

Its the left front bearing that's toast. They want to do both sides $1150 bucks.

Woa, is that just the beariangs?

That seems awful high for just the two bearings. Are they doing anything else?

The hub and bearing assemblies are available (even at retail) for around 200 or maybe even less.

An hour a piece labor puts you at around 600 give or take.

Yep. That's the dealer making $$. Thats all they had on the quote was both front sides bearings.

But lucky me, my buddy did them for me for 100 bucks labor, and I got the parts for 240.

Shes drivin like a champ again!
