Our 92 Explorer started just registering about 25mph lower than actual speed. Then would shoot all over the place. Replaced the 17 tooth drive gear, it was very worn, now it is back to registering about 25mph low again. Do we need to replace the driven gear inside the transfer case? Is there an easier way to get to that than to take it apart? Before we replace the 17 tooth, the cable worked when tried with a drill, so were hoping that would fix it but it didn't. Help!

Lift and support the rear of the vehicle. Remove the speedometer drive and look in the trans with a flashlight while turning the rear driveshaft, see if the gear is ok, without any grind marks on it from the other gear slipping. Is the gear located in the tailshaft of the trans? If so you should be able to unbolt just the tailshaft an repalce the gear if necessary
