Transfer Case Blues

If you drive a 4×4, you know how important the transfer case is to the overall operation of your truck or SUV. The transfer case is what delivers the power and gets the wheels turning to tackle tricky terrain, so when it makes noise, you need to pay attention. If your transfer case is making noises, see us at the Rairdon service center for diagnosis and repair.


Components of a Transfer Case

The transfer case is attached to the transmission and made up of many parts to achieve its goal of engaging all four wheels, which increases the potential for something to go wrong. Components of the transfer case include a chain, case, lubrication system and vacuum lines.


Common Transfer Case Noises

Any time you hear your transfer case making strange noises, do not hesitate to bring it in. If you hear any type of grinding or knocking, have the vehicle towed in to the shop instead. Common sounds that don’t belong include:

  • Grinding
  • Knocking or clunking
  • Whining
  • Sounds when decelerating or switching into 4×4
  • 4×4 just isn’t working properly or struggles to engage.


What You Can Do at Home

Whether your vehicle is under warranty or not, you should not attempt to tackle the transfer case. If you have a warranty, and you attempt to do your own repairs, you may run into warranty issues. You can, however, drain and replace the transfer case fluid to see if that resolves the issue. If it does not, look for damp spots or pinholes on the transfer case. Report any visual signs, sounds and performance issues when you bring your truck or SUV in to the shop.
