Rear Wheel Speed Sensor: Installation

If original sensor is being installed, remove any remaining pieces of cardboard spacer from sensor pickup face. Use dry shop towel only to remove old spacer material.
Insert sensor wire through support plate hole. Then seat sensor grommet in support plate.
Apply Mopar Lock N' Seal or Loctite® 242 to original sensor bolt. Use new bolt if original is worn or damaged.
Install sensor bolt finger tight only at this time.

If original rear sensor was installed, adjust sensor air gap to 0.28-1.5 mm (0.011-0.059 in.). Use feeler gauge to measure air gap. See Fig 1. Tighten sensor bolt to 12-14 N.m (106-124 in. lbs.).

3 - TONE RING

If new sensor was installed, push cardboard spacer on sensor face against tone ring. See Fig 2. Then tighten sensor bolt to 12-14 N.m (106-124 in. lbs.). Correct air gap will be established as tone ring rotates and peels spacer off sensor face.
