have a 99 ram 2500 4wd quad cab 5.7 ltr (love it) Pulling a travel trailer down highway, all at once the speedometer quit and the BRAKE and ABS lights came on. The brakes continued to work, but the lights remained on on the instrument panel.Fuses look OK.An inexpensive computer diagnostic device says there is a "speedometer sensor failure". Any advice? Will this eventually impact the brakes?

 

speed sensor, either in the top of the rear differential or transmission tailshaft.

 

yeah what he just said hahaha...my bro inlaw had an 02 ram that had the sensor on top of the rear diff... i took it off and man was that thing shot ..pull it off and see what she looks like ...dont think the part was too much around 20 somethin
