Well, I tore into things today. Check the grounds behind the headlight. They look great. Checked front wheel sensors. Right side was original and looked ok. Left side looked new and was spliced at the plug under the hood. I'm assuming it had been replaced as I've seen them sold without the plug. Checked the hub. Looked great, all teeth looked great. No slop or play in the bearings, joints, or rod ends. Checked sensors for resistance. Got 1022ohms on the left, 1032ohms on the right. I think they are both on the high end of ok, not sure. I think I recall reading 950-1050 is ok.
Seeing as everything checked out, I cleaned things up, lubed all the little bits, buttoned it up, and test drove it. As I figured, nothing had changed. Brakes kicked in as soon as I put my foot on the accelerator. Traction control light came on during this then went off. ABS light came on and remained on. Pulled it back in the driveway.
The truck needs to get me to work Monday, so out of desperation, I just unpluged the two front sensors. This triggered an inop fail of the sensors and shut down the abs/tc. At least this is my thought. The result was that the truck is now at least drivable, the 3 Amigos are back, and I'm no further than I started. Lol
I'm guessing the next step will be the dreaded modulator fix? Any thoughts?
