Transfer Case Guides





Four wheels are better. Whether it's a car or a truck, four wheels will give you much better grip on the road and improved handling under any road condition. Four wheel drive (4WD) vehicles are built for more efficient performance, made possible by the transfer case. It distributes, torque from the transmission to either both front and rear drive axles (4WD mode), or the rear axle alone (2WD mode).4WD comes in handy when driving on rocky or muddy surfaces, or when racing. An important benefit of 4WD is felt while cornering. The amount of understeer is limited, letting you accelerate sooner out of a corner. Like all car parts, however, the transfer case can endure wear on its gears and shafts.If its 4WD shifter jumps out of or refuses to shift into mode, then it's probably due for a replacement. Just as well, Carparts has stocks available.


• Our transfer cases provide seamless transition between 2WD and 4WD.

• All transfer cases we offer provide a direct, perfect fit.

• Our transfer cases last longer than stock.

Transfer Case Shopping 101

Looking for a transfer case can be easy. Getting your hands on the right one can be tricky. There are a lot of transfer cases out there in the market, which makes the decision difficult and the search tiring. Though this can be a stressful task to the majority, ending up with the right one will make you feel that your efforts were paid off.

Housing Type

  1. Married: This type is common among four-wheel drive cars. This is an important part of the transmission.
  2. Divorced/Independent: For wheelbase cars, such as military or commercial trucks, the divorced/independent transfer case is preferred. Unlike the married transfer case, this is separate from the transmission.

Drive Type

  1. Chain-driven: If you're looking for a quieter transfer case, then this is the type that you should get. This is commonly used in compact trucks, jeeps, full-size trucks, and SUVs.
  2. Gear-driven: This type is louder than the chain-driven one. Transfer cases of this kind can use sets of gears to drive either the front or both the rear and front drive shafts. This is common among large trucks.

Remember:

  • Seek for a highly regarded supplier. To be able to verify if the dealer is reliable, speak to past customers and ask for feedback.
  • Look for a transfer case with good warranty that covers defects for at least three months.
  • Make sure to bring the vehicle identification number (VIN) to present to the supplier upon request. This can greatly assist the dealer by helping them order the right transfer case for your car.
  • Don't buy from local junkyards because you might end up ruining your vehicle instead of fixing it.

This is just a guide to help you decide the kind of transfer case you need. Remember to look for the right one so that you won't end up jeopardizing your transmission. Good luck!

Repair, Rebuild, and Restore the Transfer Case

For your four-wheel drive to be able to operate properly, it must be equipped with a correctly functioning transfer case. This is connected to the front and rear axles a well as the transmission. A common cause of problems with your truck or SUV is having a worn-out transfer case. You don't need a mechanic to get it fixed. All you have to do is follow these steps to restore your transfer case.

Difficulty level: moderate

Tools required:

  • Transfer case rebuild kit
  • Torque wrench
  • Wrench
  • Pliers
  • Electric hand-held drill
  • Heavy-duty jacks
  • Transmission fluid
  • Screwdriver

Step 1: You're required to slip under the vehicle to be able to work. So, using four heavy-duty jacks, raise your car. Be sure to use one jack for each of the wheels.

Step 2: Remove the bolts that hold the skip plate in place by using an electric hand-held drill. The plate is responsible for housing the transfer case inside the vehicle. Place the bolts and place aside.

Step 3: Look for the drain plug that holds the fluid inside that keeps the transfer case lubricated. Open the plug to drain the liquid from the case.

Step 4: Using the wrench, remove the bolts and nuts from the four-wheel drive sensor, front drive shaft, shifter linkage, and rear drive shaft. After, remove the transfer case. Use screwdrivers, pliers, and wrenches to take out the screws and bolts that hold the parts in place. Set them aside so that you can focus on the transfer case. Remove the sensor and disconnect the hose.

Step 5: Use the electric hand-held drill to loosen and remove the bolts on the cover of the transfer case. Take the retaining clip slide out from the case oiler from the shaft. Apply your pliers inside the lid to be able to get rid of the clip.

Step 6: Take the drill and use it to remove the bolts that hold the snap ring, viscous clutch coupling, output shaft drive, chain, drive gear, front output drive gear, shifter shaft, input shaft seal retainer, input shaft snap ring, output flange, output shaft and input shaft. Do these in the right order. The rebuild kit has each of these parts, which will require you to replace in the transfer case.

Step 7: Mount the new parts that are included in the rebuild kit. Add transmission fluid to be able to lubricate the replacement parts when you install them.

Step 8: Close the transfer case by reinserting the oiler disc and snap the retainer clip back in place. Line up the cover on the case using a torque wrench to tighten the bolts.

Step 9: Replace the transfer case back to its position in the car. Secure the bolts holding it in place using the electric drill or wrench. Remove the plug cap and fill the case with the right amount of transmission fluid and put the plug back. And you're done!

Essential Underhood Maintenance Tips from Our Chief MechanicIn the past, cars required constant adjustments to mechanical bits, such as carburetors and ignition points. Thankfully, today’s vehicles are governed by computers and other electronics—and that means far less tuning is required. Also, because modern automotive parts and supplies generally last longer, maintenance is kept to a minimum.
