The front drive shaft will not turn in either 4 low or 4high because it is in 4wd. You will need to disengage the hub locks to be able to turn the drive shaft in any ratio (2h-2l-4h -4l) as the diff will not allow the shaft to turn unless it can move the vehicle . The biggest mistake is to drive in 4wd on hard surfaces which results in a drive line torque wind up which creates extra load in the whole gearbox, transfer case and diffs and creates hard steering problems . For the hard pull to the right I would be checking for failing "U" joints or cv joints that are binding up.

SOURCE: my jeep will not shift into 4low but 2wd and part

Well, in the future it would be better to let us know what it is exactly that you drive, (cherokee, grand, jk, cj, ....)however, i'm guessing from the picture that you drive a grand. I dont know how long you have owned it or if you have put it in 4 low before, but you need to put the normal transmission in neutral before shifting to 4 low using the transfer case (the thing that gives you 4wheel drive via the lever) However, on your vehicle, if you have full time 4 wheel, i think you have the selec-trac transfer case and only have a switch. According to the Jeep website and i'm assuming your manual, you need to slow the vehicle to 2-3 miles per hour and then place it in neutral before attempting to shift to 4 low.

SOURCE: My 2002 2500HD 4x4 front axle not engaging

Try jacking up one side of the front and putting it on a jackstand. Then turn key on(but dont start it) and put it in 4hi. Try to spin the tire in the air. The drive shaft should not turn nor the wheel. If the wheel does then maybe the acuator is not moving in the axle. It worked when you pulled it out but it might be hanging up on something in the axle.

SOURCE: whining/grinding noise at deceleration

We have the same problem at our shop. We haven't rebuilt the front differential yet. We tried 3 different shafts on 2 different Jeeps and the noise is on both just the same. By greasing the front driveshaft cv joint, we got he noise to quiet some, but it is still way to loud. With the driveshaft out, the noise is gone. We are about to buy a new shaft from the dealer for $600. There are some service bulletins about some noisy driveshafts.

O99 jeep grand cherokee 4wd low does not work


This jeep is all wheeldrive and has a lever to go from 4high and 4low,first take a look at the transfer case linkage to make sure linkage is connected and not broken or frozen, alot of times the linkage freezes up from lack of use and sometimes bends or breaks so look at that first. if the linkage is good and no problem with it then we go on to the transfer case, take note that bent linkage will make it not go into 4low, okay the next step will need the transfer case to be checked for a inside bent fork or broken fork this will need to be done by a shop. the case needs to be removed and opened up to check the shift fork. good luck, hope this is helpful.johnjohn2_64.gif

After switching from 4x4 LOW back to AWD, the transmission stayed in 4x4LOW.


This happens now and again on 4X4's. You must not continue to operate it on normal "dry" surfaces until you disengage these hubs. Permanent damage will result. First thing to do is make sure you are on wet, loose gravel, sand, dirt, etc. Switch transfer case back to 4Low. With steering straight move a little forward and without hitting the brake slip in neutral allowing truck to come to rest by itself. Switch Transfer case to next position, I assume 4low. Place in drive and drive forward and backward until you feel it come out of 4 low. You don't have to drive it crazy back and forth, just 5MPH normal back and forth maybe 20 feet forward and 20 feet backward. It's good to allow the truck to stop by itself allowing the hubs to spin freely then placing in reverse doing the same. Apply brake, repeat until unlocked. You may find that if it is not unlocking, try to push lever back into 4low, power on, the release accelerator, switch to 4high all the while it is drifting and gently power on again. If you drive on solid surfaces ignoring the driveline, you will bind the axles and destroy some element of your drive line...The weakest points first. Hope this help and do not forget to rate this high if it helped you.

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.

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.

GMC '91 Jimmy, Transfer case. When in two wheel drive I hear a slight grinding noise and rattling noise. When in 4 wheel no noise. 330,000 miles, could something be worn? What keeps the transfer case gear...


Remove the transfer case and strip it down,wash it out and replace whatever is worn.
330,000 miles is unrealistic
Your chain is worn and stretched for sure, and rattling and may be cutting into the case.
Don't install another salvage yard unit, unless you can not repair yours. Then strip down whatever you purchase, and go thru it also.

Won,t shift transfer case into 4wheel drive


Is the truck on the fly 4X4 push button or is there a lever on the floor you pull into 4 wheel drive? Located on the back of the transfer case not hard to change few bolts and a wire harness. Does the front drive shaft turn when you put it in 4x4 and the front wheels won't ingage? If so then its not your transfer case its the actulator on the front axle at the gear hub or pumpkin it will have two 10mm bolts and a black plastic cover if so remove cover and spray actulator shaft with wd-40.

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
