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
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
most speedo cables attached directly to the adaptor that holds the drive gear in place in the transmission housing. This adaptor can be removed and the gear comes out with it . The teeth can be inspected and if they are not full and in tact then it is possible that the meshing with the drive gear on the output shaft is not happening. replacement speedo gears are available but you will need the one you have as the gears have several different teeth ratios to allow for speedo corrections
You need some very specialized tools to do that You'll need a jack to hold the transfer case once you remove all the bolts holding it to the transmission. Remove the drive shafts.Then you'll need to remove the transmission, again with a supporting jack. Once that has been accomplished , remove the bolts holding the clutch to the flywheel. I'd replace the pilot bearing in the flywheel that holds the input shaft to the gearbox before proceeding. There are special tools available to do that. Now assemble the clutch disk and the clutch plate and put the bolts back in without tightening them. Now take the clutch alignment tool and push it thru the clutch disk and into the new pilot bearing. position it so the clutch disk is dead center in the clutch plate and then finish tightening the bolts Put a new throw out bearing on the clutch release lever and reinstall the transmission and transfer case. Reinstall the drive shafts and replace any gear oil that may have spilled out of the transmission or transfer case. Adjust the clutch pedal clearance to spec and you're done.
You could try removing a driveshaft and driving the car, and if the vibration persists reinstall the one driveline and remove the other. If the condition is still present there could be something going on in the transmission or transfer case. If you have access to a vehicle lift you might try running the car with hte wheels off the ground and see if you can discern anything "wobbling"" as it rotates.
You need to adjust the 4x4 shifter itself. That's your only problem. Moving the shifter isn't putting the transfer case into gear and speedo will move, whirring sound is just the bearings spinning. Re-set the 4x4 shifter linkage to proper specs.
You will have to make room by removing the bottom cover under the dash,and reach and feel for the speedo cable retainer.It will either squese together the plastic retainer that surrounds the cable at the speedo,or push a steel clip toward the speedo,and pull the cable out after doing this.Pull the cable down to were you can see it.Take some needle nose pliers,and grab the center cable,and pull it out of the cable casing,about 3 feet.Grease the cable with a heavey grease all up and down the cable,it will be messy.Feed the cable back into the cable casing and when you get to where it will not go all the way in,push and turn the cable until it aligns up with the gear in the transmission.If the cable will not come out of the casing ,then remove the end at the trans,and remove the retaining clip.
Transmission are kinda tricky. Yes you'll have to take the t-case off. Transmissions won't just fall apart when you break them open. But first things first. What's it doing. And if you don't really know anything about transmissions, I would give it to a shop to rebuild. Won't cost very much.
