The car is a mind reader, I swear. I thought to myself as I was swapping the right steering knuckle in a couple weeks ago: “boy these wheel speed sensors last a long time”.

Yesterday I was rewarded with the amber trifecta and inop speedometer. The foxwell confirms a left rear wheel speed sensor code and “0” mph on the live data on a drive around the block. Unlike when the DSC module crapped out, the car drives fine so at least I didn’t have to pay for overnight shipping on a replacement. The rears are relatively inexpensive so I bought two, and two connectors which get very brittle. I sprung for one front sensor, which are more pricy. I’ll replace the left front when I swap the “new” knuckle with bearing and ball joint in on that side. It’s built and ready to go when I find some time. The eBay knuckle came with a sensor hanging on it, so I’ll consider that a spare for the front.
