need some help guys my abs light is comming on and my sppedo is floating around crazy.The other day i was having trouble with my trans mission shifting erraticly so i changed the speed sensor and the shifting seemed to quit.Then my abs light started coming on and my speedo is floating around.So i went and got another sensor hoping it was bad.No change.Today i was driving home and my abs light came on and after a while my speedo droped to zero when i was on the highway and my truck down shifted and hit about 4500rpms.I got off on the ramp and it quit then continued on down the road and it did it one more time before i got home.ive changed the sensor twice and also cleaned and greased the plugs under the cab on the drivers side.I also noticed a ticking behind the dash when i push on the brake pedal behind the dash on the drivers side if anyone has heard of that.

Are you changing the sensor on the rear differential?

Electronic Speedometer (1995-Up):

In 1995 the Ranger stopped using a mechanical speedometer cable and relied on the VSS in the transmission/transfer case to provide it with a signal for speed.

The 1998-2000 Rangers are not equipped with a VSS (Vehicle Speed Sensor). The PCM (Powertrain Control Module) receives vehicle speed information from the antilock brake system rear wheel speed sensor. The raw signal from the ABS/VSS sensor on the rear axle goes directly to the Explorer 4WABS module where the signal is corrected for tire diameter. Then the corrected signal is sent to the PCM, speed control, cluster, etc. In this system, the PCM is an end user of the corrected VSS signal.

I replaced mine and it was fairly easy and maybe 20 bucks.
