Failing to find the manual, you can try:
* Checking a reputable online repair manual: Sites like Chilton or Haynes often have this information. Be sure you select the correct year and model.
* Contacting a Dodge dealership: They can provide the correct torque specification.
Using the incorrect torque can lead to loose lug nuts (potentially causing a wheel to come off) or over-tightened lug nuts (damaging the wheel studs). Always use a torque wrench to ensure proper tightening.
