Noisy speedometer my 1996 Tpyota Tacoma speedometer that is clicking..what is the replacement procedure?

The click you are hearing might be a dry speedometer cable. Applying grease to the inner cable will most likely help this problem. The problem is getting to the cable behind the speedometer/dash panel. You can also get to the cable from under the truck. if you crawl under the truck and look at the smaller end of the transmission, you will see the cable screwed into the tail piece of the transmission. Remove the cable from the transmission and pull the inner cable out of the outer cable. The inner cable is what spins and causes the speedometer to turn. Take regular wheel bearing grease in the palm of your hand and slid the inner cable through the grease then put the inner cable back in the outer cable. When the inner cable gets to the back of the speedometer, you will have to slowly turn the cable and give a slight pressure inward to seat the inner cable into the speedometer.

Hope this helps.

Good Luck
