The Chrysler capable scan tool is what I DON'T have. Priced them out years ago and figured it wasn't worth it. :)

Don't have a scope either.

So I took a chance today and figured I would just R&R the rears and hope it was one of those. My Wife almost t-boned someone today because the vehicle wouldn't stop in time (ABS was engaging).

Problem #1: The rears (same part# ) are cheap $20 - $30 each. The fronts are a dealer only sourced item (advance and AutoZone can get them, but they will get them from either a dealer or central warehouse), and are individual to the location, each are about $120 each.

Problem #2: I had gotten the passenger rear out and undid it from all the mounts/hangars and removed an exhaust shield to completely remove it. Went and reinstalled the new one, and the electrical plug wouldn't work. Turns out that there are two versions. Mine took a plug with a beveled corner at each of the plugs' corners. The one I had gotten had rounded corners. So I took it back. I then had to source the correct ones with the beveled edge, 1 from Napa, 1 from Advance (second location).

Happy to report that after 10 miles of driving, all seems to be well.
