Which transfer case does your truck have ?
SERVICE 4WD
Refer to
?€¢
Transfer Case Description and Operation for the Transfer Case - NVG 149-NP3


?€¢
Transfer Case Description and Operation for the Transfer Case - NVG 246-NP8


?€¢
Transfer Case Description and Operation for the Transfer Case - NVG 261-NP2


?€¢
Transfer Case Description and Operation for the Transfer Case - NVG 263-NP1


The SERVICE 4WD indicator is located in the instrument panel cluster (IPC), and shares the common power and ground of the IPC. The transfer case shift control module controls the service indicator by sending the IPC a Class 2 message. This indicator may be controlled with the scan tool using the IPC device controls.
You should take it to the dealer an have it checked for DTC'S -diagnostic trouble codes

2001 chevy blazer transfer case removal


How to Remove a Chevy Blazer Rear Transfer Case The transfer case on a Chevrolet Blazer is underneath the vehicle, mounted to the rear of the transmission. On four-wheel drive vehicles, the transfer case takes power generated by the engine and channeled through the transmission and directs it to the front and rear drive axles. Over time, the gears and bearings inside the transfer case can wear and the transfer case must be rebuilt. The transfer case on this vehicle must be removed before it can be serviced.
Things You'll Need
  • Wrench set
  • Floor jack
  • Jack stands
  • Socket set
  • Masking tape
  • Marker
  • Needle-nose pliers
Hide Instructions
  1. Removing the Driveshafts
    • 1 Disconnect the ground cable from the negative battery terminal, by using a wrench to loosen the retaining bolt and pulling the clamp off the terminal.
  • 2 Raise the vehicle and support with jack stands placed underneath the frame.
  • 3 Drain the transfer case. Locate the drain plug near the bottom of the transfer case. Place a waste oil collection pan underneath the plug and use a socket to remove it. Once all the fluid has drained out, reinstall the plug.
  • 4 Remove the bolts that connect the rear driveshaft to the rear axle yoke using a socket. Lower the driveshaft, and slide it backward underneath the rear axle to disengage it from the transfer case. Remove it from the vehicle.
  • 5 Remove the bolts that connect the front driveshaft to the front axle yoke using a socket. Lower the driveshaft, and slide it forward underneath the front axle to disengage it from the transfer case. Remove the driveshaft from the vehicle.
  • Removing the Transfer Case
    • 6 Label and disconnect the electrical wires and vacuum lines connected to the transfer case. Use masking tape and a marker.
    • 7 Remove the transfer case shifter rod. Using needle-nose pliers, remove the clip that connects the shifter rod to the transfer case. Slide the rod away from the transfer case.
    • 8 Position a floor jack underneath the transfer case. Raise it enough to take the weight of the transfer case off the transmission.
    • 9 Remove the bolts that connect the transfer case to the transmission using a socket or wrench.
    • 10 Slide the transfer case rearward to disengage it from the transfer case. Lower the floor jack, and remove the transfer case from the vehicle

    Transfer case


    A transfer case is just what it says, a transfer case. It is a case of gears that transfer power from the transmission to the front wheels. Transfer cases are only found on 4 wheel drive vehicles.

    How do u remove a transfer case


    Most suvs have the transfer case linked to the transmission. Best is to take both out at the same time.Generally:
    1. Disconnect the battery
    2. Unplug all wires from the transmission - transfer case unit. Make sure you mark them so you can reconnect them properly
    3. Get inside the car and remove the shift lever(s)
    4. Remove the starter
    5. Remove the clutch slave if there's one or disconnect all cables from the unit
    6. Support the car on stands so you can work easily under it.
    7. Drain the oil from the unit may have 1 or 2 drain plugs
    8. Remove the shafts making sure you marked the alignment where they are joined
    9. Support both the engine and the transmission unit with the appropriate jacks
    10. Unbolt the transmission from the engine
    11. Remove the unit support (s)
    12. Remove the unit from the car.
    Important to remember the type of oil that goes in the trans and in the transfer case. They may not be the same. Also, some electrical transfer cases don't use any oil.

    Transfer case removal


    first remove both front and rear driveshafts. Then remove skid plate underneath transfer case. Remember to unplug the electric motor wiring harness for explorers with electronic four wheel drive switching. Remove vacuum line on the top of transfer case. Unbolt Speedometer cable mount from top/rear of transfer case. Remove five bolts connecting the transfer case to the transmission, this step will cause some transmission fluid to leak from the shaft housing (approx. half a litre) so place a drain pan underneath. Remember to either place a jack or wood blocking under transfer case before removing the last bolt connecting the transfer case as it is heavy (approx. 80-90 lbs.).

    Transfer case removal


    Suzuki Samurai/Sidekick/Tracker 1986-1998 Repair Guide
    Transfer Case Assembly - REMOVAL & INSTALLATION

    Samurai Models
    Even the 2WD Samurai uses a transfer case. Rather than use a straight line driveshaft from the transmission to the differential, the Samurai leaves the transfer case in place and replaces its internal working with a simple offset gear mechanism, thus keeping 2 of the 3 driveshafts used in the 4WD vehicle.
    1. On 4WD vehicles, remove the transfer case shift lever.
    2. Raise and support the vehicle safely.
    3. Drain the oil from the transfer case.
    4. Matchmark and remove the driveshafts from the transfer case assembly. Not all of the driveshafts need to be completely removed from the vehicle, just unbolted from the case flanges. In most cases, the shaft or shafts on one side of the transfer case can be repositioned and supported out of the way.
    5. Support the transfer case using a suitable transmission jack.
    6. Disconnect the speedometer cable from the transfer case.
    7. On 4WD vehicles, disconnect the 4WD switch lead wire at the coupler.
    8. Remove the three mounting bolts and/or nuts securing the transfer case to the chassis, as applicable.
    9. Carefully lower the transfer case from the vehicle.
    To install:
    1. Position and install the transfer case. Tighten the mounting bolts to 159-248 inch lbs. (18-28 Nm) and/or the mounting nuts to 19-25 ft. lbs. (25-34 Nm).
    2. On 4WD vehicles, connect the 4WD switch lead wire at the coupler.
    3. Connect the speedometer cable to the transfer case.
    4. Properly refill the transfer case with an approved type of gear oil.
    5. Align and install the driveshafts to the transfer case.
    6. On 4WD vehicles, install the transfer case shift lever.
    7. Remove the jackstands and carefully lower the vehicle.
    Sidekick, Tracker, Sidekick Sport and X-90 Models
    On these models the transfer case is bolted to the transmission and takes the place of the 2WD transmission's extension housing. Therefore, transfer case is removed or installed as part of the transmission assembly.

    Hope this help (remember rated this and comment).
