I'm Mike Green. I'm one of the owners of 1A Auto. I want to help you save time and money repairing and maintaining your vehicle. I'm going to use my 20 plus years of experience restoring and repairing cars and trucks like this to show you to correctly to install parts from 1AAuto.com. The right part installed correctly, that's going to save you time and money. Thank you, enjoy the video.
In this video, we are going to replace the front ABS harness on this 2002 GMC Sierra, same as most of these vehicles from '99 to '06. These can get broken, you can hit an obstruction, and the harness can get torn or they can just sometimes wear out and break over time. We shall need our 18, 21 and 22 mm sockets with the ratchet. You may need a pipe or breaker bar for some leverage on some of those bolts that are little difficult; Allen wrench and adjustable wrench, large flat plate screwdriver, and a pair of pliers.
Start out by using a 21 mm socket and just loosening the plastic retainers and taking off the hubcap if you have the style wheels. You want to raise and secure the vehicle if you are not working with air tools like I'm, then loosen the lug nuts for the wheels on the ground, then raise it with a jack, support it with a jack stand and remove the lug nuts rest of the way and remove the tire.
Okay we are going to remove the caliper, which is two 18 mm bolts; one there and one up here. I'm going to speed things along here and you can see I'm able to get those bolts with the ratchet on. You might want to use a pipe to give you a little extra leverage. I will show that in the next step, and then I actually go to the air tools to get the bolts off the rest of the way. Then I pick a screwdriver; put it in this hole in the caliper here; prying out the caliper. This forces the piston back while I get the caliper up and off. Then you got to take off this caliper bracket, which involves taking off these two bolts here.
Okay fast forward again. You all notice I have a pipe there, that's for some extra leverage on these bolts. These are 21 mm bolts in size and we will just fast forward through me taking them out. Then you are going to pull your brake rotor right off as well. The brake rotor has threaded holes here. If you couldn't get it off, it doesn't pull off, you want to use an M10 or M12 7 cm long bolt and you put the bolts in there and that forces the rotor off. Here I'm just taking one of my bolts and my caliper bracket and just threading it in on a few turns and then putting my brake caliper back on just kind of threading that bolt in and putting on a few turns. This just puts the caliper on a safe place while I'm working.
You need to get here; here is your sensor, the end of your sensor right here. Now I'm going to take an Allen wrench, put it in that bolt that's holding the sensor or adjustable wrench. This whole things is leveraged on this power wrench. This is the bolt, pair of pliers where I want the sensor, pull it up and out. Pull the sensor up and out. Pull this off for a second, put your sensor right up through there. Now using one of these pair of pliers and force these clips out. There is one more up here. It comes out and then right here near your shocks. Right up here near your shocks for the connectors, use a screw driver, pry the pin up and out and very carefully cut the bottom side and over here, the bottom side, all right unplug it. I think here is my old sensor. New sensor from 1A Auto you can see has all the same hooks and connectors.
Start up here and push it back in just like before, put this heat shield down around it, pick the shock, wrap the heat shields down, press it down in. Press that in. Here this pin didn't actually come out. That probably needs a little punch. Punch that through. Down in, that goes in there. Put that right through; just make sure you clean the sensor off. Guide that sensor into the hole with my thumb and then down in. Allen wrench and the screw. I'll just speed it up here as we screw in with the Allen wrench and then use the adjustable wrench to tighten it up and continue with the fast motion as we take that bolt that was holding the caliper, put the caliper up, and put the bracket back on, thread the bolts in and then preliminarily tighten them.
Torque these to a 110 foot pounds and put the brake shoes back on here. Now bring that calipers down and start those long bolts in. You want to make sure that those are nice and clean and have some grease on them because the caliper needs to slide back and forth on those bolts. Torque these caliper bolts to 85 food pounds. Fast forward again here as we hoist the tire up on. You want to start all lug nuts by hand first and then I just use the air ratchet or the impact wrench just to tighten up the lug nuts preliminarily. I don't tighten them all the way up until the vehicle is on the ground.
The wheel works to 120 foot pounds. Again we will speed up here and you can see that kind of cross into the opposite lug nuts and then afterwards I actually go around one by one and just make sure they are all torqued. Okay now put the cap back on and then please stay with it for one more very important step. Make sure that whenever you are taking your brake spare parts that before your drive your vehicle, you pump your brakes so much times and then do test it up before road testing it.

Excellent fit, quick shipping. Video helpful - but could use a section on what to do if the old sensor tip stays in the wheel. Heat up a screw or bolt slightly larger than the copper windings, screw it into the cap still in your wheel about 1/2 way...... quench with cold water and use the screw or bolt to wiggle the cap free!!!!
Worked as expected

Purchased the speed sensors at a great price. They were easy to install and corrected my low speed abs activation. Some people say to replace the whole hub but in my case the sensor alone did the trick. GMC 2500 140000 mi

The part was a exact match for my truck and eliminated the problem I was having, but it would have been nice if they would have provided a new screw to mount the new sensor. The old screws were pretty corroded but we had to reuse them anyway because new screws were not provided.
Have BRAKES!

I ordered the wheel speed sensors (WSS) for my truck. Website said they fit my make and model. When the WSSs arrived and I started my job. What I pulled off did look exactly like what I bought. They did not fit. I could not get them to fit into my wheel bearing. Turns out the new ones were sent with a larger O-ring that made them not fit.
I tried to swap O-rings from the WSSs I took off, that worked.
One WSS was 100 ohms less that the other one. When I tested before start-up. I was not happy with this.
When I started up my truck and cleared my computer with my scanner. Codes popped right back up saying both WSSs are not reading.
I have not tried to return the parts for my money back because they are on my truck now, and the 1A Auto website states they do not refund money on electronic parts.
I had module master test my EBCM, they said it is fine for voltage out to the WSSs. When I test at the plug where the WSSs plug into I have the same voltage. I am going to buy my new WSSs from
Worked well
