Is there an electric or vacuum switch on a 2001 chevy blazer


There are 2 models here the push button will flash if the system is not engaging or disengaging properly . If front drive shaft is turning. That is with car raised and supported . if front drive axles do not turn then the axle actuator is not engaging axle shaft passenger side. Remove actuator and manually engage shifting collar with a screwdriver still does not turn then inner axle is twisted.

4wd not engaging. Check actuator and seems to working properly. Jacked front end up and and when in 4wd the front tires spin freely. Any suggestions?


Does the driveshaft for the front wheels turn when in 4wd? The actuater might work but the diff lock for the front wheels might have broken. If the front driveshaft does not turn when in 4wd, the transfer case might be the problem.

The Selectable Four Wheel Drive (S4WD) Front Axle consist of the following components:
• Differential Carrier Housing
• Differential Case Assembly
• Inner Axle Shaft
• Intermediate Shaft Bearing Assembly (located on the right side of the oil pan)
• Electric Motor Actuator
The front axle on Selectable Four Wheel Drive (S4WD) model vehicles uses a disconnect feature mounted on the right side of the oil pan in order to engage and disengage the front axle. When the driver engages the 4WD system, the Transfer Case Control Module sends a signal to the electric motor actuator to energize and extend the plunger inside. The extended plunger moves the clutch fork and clutch fork sleeve across from the clutch fork outer gear that is splined to the right side wheel drive shaft to the clutch fork inner gear that is splined to the inner axle shaft. The locking of the two gears allows the axle to operate in the same manner as a semi-floating rear axle. A propeller shaft connects the transfer case to the front axle. The differential carrier assembly uses a conventional ring and pinion gear set to transmit the driving force of the engine to the wheels. The open differential allows the wheels to turn at different rates of speed while the axle continues to transmit the driving force. This prevents tire scuffing when going around corners and premature wear on internal axle parts. The ring and pinion set and the differential are contained within the carrier. The axle identification number is located on top of the differential carrier assembly or on a label on the bottom of the right half of differential carrier assembly. The wheel drive shafts are completely flexible assemblies consisting of inner and outer constant velocity CV joints protected by thermoplastic boots and connected by a wheel drive shaft.

maby im wrong but if you rev up and only rear wheels spin that means that it might be 4 wheel drive but not constant 4 wheel drive or diff lock system ,,,, ,, in 4 wheel drive all wheells will turn together but if pressure of slip is bad enough or torque high enough only 2 wheels will drive ,,, thats why diff lock locks wheels together in each axle to over come this ,,, all wheel drive like in landrover locks all 4 wheels together to ensure all wheels rotate to give best grip

Transfer case on 2006 F150 will engage but no power to front wheels?


SOUNDS LIKE A BAD HUB TRY THIS TO DIAGNOSE THE PROBLEM

Put the transmission in park, set the parking brake and raise the chassis so one of the front wheels is off the ground while the other is still on the ground. When the transfer case is in two-wheel drive, the hubs should be released allowing the wheels to turn freely when spun by hand. If the axle shaft turns when you spin the wheel, it means the hub has not disengaged.
To check engagement, rotate the axle shaft backwards. This should lock the hub. Try turning the wheel by hand again. The axle shaft should now turn with the wheel if the hub is locked. If the hub fails to lock, the hub will have to be disassembled and inspected or replaced.
To check release, hold the axle shaft steady and rotate the wheel backwards. You should hear a click as the locking mechanism slides back out and disengages the hub. Rotate the wheel forward again and it should turn freely.
Another way to check the hubs is to raise the vehicle on a frame contact lift so all four wheels are off the ground. Then start the engine and place the transfer case in four-wheel drive and the transmission in drive. If the front wheels don't turn, look at the front axle shafts. If both shafts are turning, but one wheel is not, the problem is a bad hub on the wheel that isn't turning. If the front driveshafts are not turning when the transfer case is in four-wheel drive, the problem is inside the differential (broken side gears) or the transfer case (broken chain, shift linkage, etc.). If the driveshaft between the transfer case and differential is turning, the problem is in the differential. If the driveshaft is not turning, the vehicle is going to need repairs to the transfer case.
Hope this helps.

4wheel drive wont engage


First, start checking the fuses an there is also an electrial activaced switch at the transmission or transfer case that may be bad.

95-96
Your control knob should say 2wd, 4auto, 4low.

First, we need to narrow it down to a transfer case issue, or a front axle issue.
Step 1) Jack up the front end and place it securely on jack stands.
Step 2) Verify that the front driveshaft turns by hand. When turning the front driveshaft by hand, the front wheels may or may not turn. Do not be alarmed if they don't turn. This is normal for your vehicle.
Step 3) Start the vehicle and let it idle. Place your foot firmly on the brakes, place the transmission in NEUTRAL, engage 4low, then place the vehicle back in park. DO NOT ENGAGE ANY GEAR!! The lurch as the transmission engages could cause the vehicle to lurch and potentially fall off the jack stands.**If you can turn the front driveshaft, the transfer case is not locking. This could be due to a mechanical issue with the transfer case itself, or an electrical gremlin with the control system. Start a new thread with the results of your checks, and we'll go from there.
**If the front driveshaft does not turn, the transfer case is locking properly and we need to continue searching.
Step 4) With the front wheels in the air, engine idling in PARK, spin one front wheel. The other wheel should spin the opposite direction. If both wheels spin in opposite directions, then the front axle *should* be properly engaged. Take it for a test drive (after safely lowering it to the ground, of course). If the front wheels do not spin in opposite directions, there is a problem with the front axle. This could be due to a mechanical problem with the diff, or a failure of the center axle disconnect to engage the passenger side axle shaft. Start a new thread with the results of your checks, and we'll go from there.

Troubleshooting the CAD on a 95-96 is a bit more involved than I want to get into here, and the problems can vary widely. This'll get you started.

Step 2) Verify that the front driveshaft turns by hand. When turning the front driveshaft by hand, the front wheels should turn. (If only one turns, don't be alarmed. One wheel sometimes has more resistance in the brakes, bearings, or CV joints. This is normal)
Step 3) Start the vehicle and let it idle in PARK. Engage 4high. DO NOT PUT THE VEHICLE IN GEAR!!! Crawl underneath and see if you can turn the front driveshaft.

Your control knob should say 2wd, 4high, 4low

The transfer case in these trucks functions essentially like the 1st-gens' 13-54 t-case. (i.e. it uses a lockup collar engaged by the transfer case shift motor) The troubleshooting procedure is very similar, but you don't need to worry about hubs or center-axle disconnects engaging.

Step 1) Jack up the front end and place it securely on jack stands.
Step 2) Verify that the front driveshaft turns by hand. When turning the front driveshaft by hand, the front wheels should turn. (If only one turns, don't be alarmed. One wheel sometimes has more resistance in the brakes, bearings, or CV joints. This is normal)
Step 3) Start the vehicle and let it idle in PARK. Engage 4high. DO NOT PUT THE VEHICLE IN GEAR!!! Crawl underneath and see if you can turn the front driveshaft.
**If you can turn the front driveshaft, the transfer case is not locking. The shift motor could be falsely reading an incorrect t-case position, or it could be a mechanical issue with the case itself. Start a new thread with the results of your checks, and we'll go from there.
**If the front driveshaft does not turn, the transfer case is locking properly and we need to continue searching.
Step 4) With the front wheels in the air, engine idling in PARK, spin one front wheel. The other wheel should spin the opposite direction. If it does, the system should be properly engaged. Safely lower the vehicle to the ground and take it for a test drive. If the wheels do NOT spin in opposite directions, there is a problem with the front differential or axle. Start a new thread with the results of your checks, and we'll go from there.

Banging noise in 4 wheel drive under torque. front hub questions.


Hello scotch1812, those of us that still enjoy the square headlights have to stick together! The front axle in our YJ's are dana 30 with a high pinion! The high pinion make the ring and pinion spin in a reverse rotation from the dana 30 found in CJ and TJ Jeeps. When Chrysler designed the YJ front axle, they removed the manual hubs like those found in CJ models and installed a vacuum disconnect on the passenger side axle shaft. The passenger side axle shaft is 2 piece with a sleeve that is moved into place to connect the 2 pieces of axle shaft when you shift the transfer case into 4 wheel drive. This is done via a vacuum module mounted on the axle housing. If your module diaphram goes bad you have no 4WD! If your vacuum hose comes off of the module or breaks you have no 4WD. Now when your transfer case is in 2WD the front driveshaft does not turn. The vacuum disconnect allows this to happen. As for the hubs, they are simply hubs with sealed bearings and a universal joint to allow your front wheels to turn left and right. If you hear the banging noise in 2WD it could be a bad universal joint in one of your axle shafts.

Now if you are hearing the banging noise only when you are in 4WD there could be a number of reasons. You could have a broken axle shaft or a bad bearing in your ring and pinion. Your front driveshaft could be bent or at least not straight. I would start with the driveshaft. Just lay under the Jeep (Not running! With emergency brake set!) and spin the front driveshaft. If it spins true and doesn't have an out of round rotation we can rule that out! Also, grab it and push it and pull it to check to see if your universal joints in the drive shaft are gor and tight! They can make a grinding noise or popping noise if they are bad!

Try these and let me know what you find! We will find your problem!

Transfer case wont engage


shift into 4wd and move truck a couple of feet.
if light is still off, park truck block the wheels set the park brake jack right front wheel and try to hand spin the wheel if wheel doesn't turn 4x4 is functioning properly but there is a wiring problem use an ohmmeter to check the 4x4 switch wiring fuse and bulb
if wheel turns freely the front axle or transfer case is not engaged
attempt to hand spin the front driveshft if the driveshaft will spin the transfer case is not engaged check the transfer case shift linkage, problem is in linkage or transfer case internals
if the driveshaft will not spin the transfer case is engaged properly
with trnsmission in neutral or park start engine measure vacuum on the two vac lines at front axle shift motor . one line should have approx 20" vacuum. other line should have none
if no vacuum measured look for vac leak or bad vac switch
if both lines have vac look for a bad vac swithc or ruptured cad actuator diaphragm
if one line has 20" +- VAC
move transfer case lever to 2wd measure vac again lines should have swapped vac signals
if no vac switch bad or 4wd shift likage needs adjusting
if yes vac motor bad or stuck or shift fork stuck
remove vac shift motor from the axle attach vac lines to shift motor engage disengage 4wd
does shift motor plunger move at least 1/2 inch
no shift motor bad
yes check axle shift fork and vac motor for binging

Place vehicle in 4wd (high or low). This will hold the front drive shaft still for the rest of the test. Jack up the front end of the vehicle. Remove the actuator. Have a buddy spin the right front wheel while you use a long punch or screwdriver to try to manually engage the diff. The left front wheel should spin in the other direction if the diff is good. Also before you check the diff you need to grab the front driveshaft and make sure it is locked, If it spins freely when the truck is in park and in 4wd with the front end raised then problem is in transfer case. If you can't make the diff engage manually with punch then the problem is in the diff. If front diff engages manually then the problem is the actuator. Hope this helps..
