How do I install a speed sensor for a 2000 Jeep Grand Cherokee ?

Answer 1

What are you trying to accomplish?
The car has two speed sensors. One is in the rear of the transmission, and one is in the top of the differential. It will make a difference to know which one you want to replace.
Both are simple to replace, both the same process; disconnect the electrical connector, then remove the retaining bolt, remove the old sensor, replace with he new unit, and replace the bolt and connect the electrical connection.
