So a week or so back, after driving the Impala on a hot, rainy day, I get a message on the dash that says "Service Traction Control System" and the ABS light came on.
I did some internet searches and came to the conclusion that it was probably a speed sensor. I had a friend use his fancy scan tool to tell me that that the speed sensor on the right front wheel wasn't working properly.
I had put new brake pads on the car a month or so back and found that the right front pads were worn unevenly (the inside pad was barely worn, the outside pad was almost completely shot. I figured the caliper was stuck, but I didn't replace it at the time.
Since the speed sensor is built into the hub assembly, I figured I'd kill a few birds at once and replace the hub, caliper and rotor, along with new pads up front.
Jeff (who is still at home recovering from quadruple bypass) has been going stir crazy and said for me to bring it over to his place to make use of his tools.
So, Mrs. P and I had already scheduled a vacation day for yesterday. Rather than relaxing, I figured I'd work on the car.
Got over to Jeff's with the parts at around 90 yesterday morning. Jacked the car up, took off the wheel, took off the caliper and caliper bracket, removed the big bolt holding the hub on the front and the three bolts on the back.
That sucker WOULD NOT COME OFF! I tried tapping it with a 3 lb hammer. I tried using a wheel puller. It would not budge. We were just about to pull the out the torch and heat it up to break it loose, but as a last resort, I put the big nut back on and thumped it with an 8 lb sledge hammer. It moved! A few more hits got it out to the point that the nut was flush with the surface of the hub, but it still wouldn't come off of the splines. The wheel puller went back on, and finally the hub came off. It took over an hour of manipulating the stupid thing to get it off the car.
I then re-assembled and we bled the brakes. And we bled the brakes. And we bled the brakes. They just would not bleed. Finally I realized that the bleed nipple was on the bottom of the caliper. Advance Auto had given me the left side caliper, not the right side caliper.
So, we called all of the usual parts stores in the area. Nobody had the right side caliper in stock. Then I remembered that an Autozone had just opened in town. They had the part! Drove back into town, got lunch and the correct caliper, went back to Jeff's and ate, then took the wrong caliper back off, put the correct one on, bled the brakes, and it worked like a charm.
Then I had to drive back into town to return the incorrect part.
So, this job that should have taken 2 hours tops kept me busy until 40 yesterday afternoon. I ended up spending about $300 in parts, and I wrenched my back and my neck pretty badly as well.
But, my efforts seem to have worked. I'm going to be really upset when Mrs. P calls today and says the warning lights came back on.
