I I have a 2018 ram speedometer quit working about 3 weeks ago. I hear a lot of talk about speed sensors but I can't locate and this truck do not see Anything on the rear differential.

I think the vehicle speed sensor for the speedo/cruise control is on the left front. (likely hub/bearing/sensor assembly.)
