How to Troubleshoot a Four-wheel-drive in a 2000 Dodge RAM

Some of Chrysler's Dodge Ram trucks are equipped with four-wheel-drive systems. The transfer case can be manually shifted with a lever, or on some models, electronically shifted through dashboard controls. Problems with a four-wheel-drive system in a 2000 Ram can be related to the controls and the environments necessary for shifting between the different types of four-wheel-drive. These kinds of issues can be corrected through troubleshooting.

Things You'll Need

  • Tire-pressure gauge
  • Allow the front or rear wheels to stop spinning if the truck won't shift into four-wheel-drive. The Dodge truck isn't equipped with synchronization, so the front and rear driveshafts must be spinning at the same speeds for the shift to take place.

  • Keep speeds below 25 miles per hour when you operate the truck in the "4LO", or four-wheel-drive low, position if results are unexpected. The engine speed is three times that of two-wheel-drive when in "4LO."

  • Check for correct tire pressure, uneven tire wear, excessive loading or cold temperatures if the truck delays in shifting out of four-wheel-drive. Check the information sticker on the driver's side door pillar for tire-inflation requirements and for weight of the vehicle and load. Remember that weight maximums include passengers as well as cargo.

  • Use the correct variant of two- or four-wheel-drive if traction is poor. Use "2H," or two-wheel drive high, for regular dry pavement. Use "4H" for slippery conditions. "N" is the neutral position for being towed and "4LO" is for deep sand, mud, water or steep inclines. You can also use it for towing heavy equipment.
