ABS Speed sensor

[Steedog]

Hey TYK,
I apologize if this topic has already been beaten. I was wondering if it's possible to replace an 07 tahoe's ABS speed sensor on my own. I can't afford 550 at the moment, and that's what the dealer wants. OR on a scale of 1-10, where would you guys rate its level of difficulty?

I guess being a newbie has its disadvantages lol

As of right now, it seems 133 peoplee have read your question.

It seems all 133 do not have the answer.

Some whiz kid will show up, just give it time!

From what I know, the sensor in these SUVs is not removable from the hub assembly. So to change it you will need to change the hub assembly also.
To do so just buy a hub for the damaged one somewhere online or local and install it by removing the brake caliper, brake rotor and then spindle assembly from the hub.
You could just do both hubs at once as preventive maintenance.
Level of difficulty is around a 5 for this fix. Its pretty straightforward, just a lot of bolt removing.

If you have a socket wrench, you'll be good.

Your abs sensors are supposed to be held down with a mounting bolt. Here is the repair guide for them:

Removal & Installation



Front

1. Raise and properly support the vehicle.
2. Remove the tire and wheel.
3. Remove the brake rotor .
4. Remove the WSS cable mounting clip from the knuckle.
5. Remove the WSS cable mounting clip from the upper control arm.
6. Remove the WSS cable mounting clip from the frame attachment point.
7. Remove the WSS cable electrical connector.
8. Remove the wheel speed sensor (WSS) mounting bolt.
   WARNING
   Carefully remove the sensor by pulling it straight out of the bore. DO NOT use a screwdriver, or other device to pry the sensor out of the bore. Prying will cause the sensor body to break off in the bore.

9. Remove the wheel speed sensor from the hub/bearing assembly.

To install:

1. Plug the WSS bore to prevent debris from falling into the hub.
2. Using a wire brush or equivalent, clean the WSS mounting surface on the hub to remove any rust or corrosion.
3. Apply a thin layer of wheel bearing lubricant to the hub surface and the sensor O-ring prior to sensor installation.
4. Install the WSS into the hub/bearing assembly. Ensure that the sensor is seated flat against the hub.
5. Install the WSS mounting bolt.
   1. Tighten the WSS mounting bolt to 13 ft. lbs. (18 Nm).
   
   
   
6. Install the WSS cable mounting clip to the knuckle.
7. Install the WSS cable mounting clip to the upper control arm.
8. Install the WSS cable mounting clip to the frame attachment point.
9. Connect the WSS cable electrical connector.
10. Install the brake rotor.
11. Install the tire and wheel.
12. Using a scan tool, perform the Diagnostic System Check - ABS

Fig. Fluid will come out of the VSS opening so be ready to catch the spillage

1. Disconnect the negative battery cable.
2. Raise and safely support the vehicle.
3. Unplug the sensor connector.

I'm almost positive the sensor on these 07 Up SUVs is part of the hub assembly so all the above directions are useless in this situation.
The above directions are just universal AutoZone directions.

 

[SunlitComet]

there are sensor part numbers available and they are sold at several parts stores seperately as well as the intructions are in order with a parts list from compnine. So if I am wrong then so is a lot of application and parts guides including ac delco.

The wheel speed sensors in the newer models is the same as in the DIy quoted below. I just double checked on that and that procedure will work for the later models as well.

dont know if this would be the same procedure but is for an older rig.... http://www.tahoeyukonforum.com/forum/showthread.php?t=29234
