SOURCE: hummer h2 transfer case

Only way for this to happen on an H2 (AWD) is for something to break rearward of the lockup hub. Take a look at the splines between the intermediate shaft and centerdifferential or even the teeth on the forward sun gear and/or stepped pinion on the center diff.

As long as you have the t-case torn down for repair be sure to upgrade to the new aluminum mode fork (production upgrade to old plastic forks thru end of 2007 or so). You should also upgrade the rear half of the housing to the 2008 version which has a pressed-in rear prop bushing (better bushing and is also replaceable.

Is it a consistent pulsing or does it get faster as the speed goes up?

SOURCE: Is differential & transfer case flush good idea at 95,600 miles?

You should have the trans., transfer, and diff. serviced, if you got an owners manual it will tell you in there at what intervals or the milage it should be done at,mostly around 35 to 50.000 you got that kind of milage on it and its never been done you better do it, the oils do break down and don't last forever, it could cost you more in the long run.

SOURCE: 01 Chevy Silverado 4 X 4 not working. 4WD light

Having the same exact problem but with my 1999 escalade. Thought it was the actuator bought a new one installed it transfer case would engage but front end wouldnt lock. Took it out of housing left it plugged in got a friend to go through all the 4wd for me and the plunger never moved out the actuator. Checked my wiring harness which is a four prong ann it had one hot prong like it is suppose to. Traced wires even replaced dash switch same problem. Taking it to local dealership tom to have it checked for codes. I was told it could be the transfercase actuator even though its workin that actuator is what sends power to the front to engage the actuator to lock the differential.

SOURCE: 1996 Yukon 4X4 Electronic Shift on Fly.

I had the same problem with the shift on the fly push-button 4x4 on my 97 Suburban. GM Shop manual indicates that it could be due to an encoder error on the actuator motor. Try pulling the transfer case fuse to reset the transfer case control module. Wait at least one minute. Re-install fuse then re-try operation. Did it last week and that saved me a trip to the dealership and extensive troubleshooting.

My 2005 jeep gr Cherokee with a 231re rear differential feels like it is dragging the wheels sideways when turning. Help. could it be the e solenoid?


not sure what that means.? not at all.
Grand Cherokee, WK , 2005
2wd or 4? must be 4 cause 231 is NP231 transfer case and not a rear end (RE?) axle name. or is 231 a typo?????????
so are you driving in 4wd, why not tell that? or 2wd.????????
if yes, then what are tires touching,
dry pavement?
ice?
or off road.?
I cant guess roads, yet, no clairvoyance , upgrade here ,yet...
the WK runs a NV140 or , NV245 transfer case (both Full time)
so how do you find one with NP231????
the rear of the transfer case has tag and clearly tell you what is there, did look first.

if in 4wd, are you using LOCK mode, or Part time mode.
or 4wd LOW, do not use low... unless you LEARN how. and where.
if yes, the car must be on ice or offroad, never ever on dry pavement unless you select FULL TIME MODEs.
the operators guide is clear on that, read it yet?>

on my WK the front axle is C200
and rear is C213, c213r has DIFFERENTIAL-VARI-LOK
no 231s used.

are you asking a VARI-lok question.
read page Chatter 3 page 204 on this, tells you how to test this.
the axle has a tag that will ID it as, C213R, if opted day 1.

When I select 4 wheel drive, why does it feel as though it is binding or dragging and whining while driving?


Depending on the specific vehicle many 4WD have a transfer case that will lock the front and rear drives shafts together. This configuration is only for slippery conditions like ice and snow or very wet or off road. When turning the radius is different between the front and rear so there is a lot of feedback to the steering wheel. This is created by the fact the front set of wheels and the rear set of wheels must make the same number of turns because of the locked transfer case.

If you attempt to drive on high friction surfaces the stress to the drive train is excessive and will cause damage. The whine and the bunny hop is the drive train attempting to release this tension. If you were on a slippery surface the tires would have much less resistance turning at slightly different rates.

Also critical is the tire size need to be the same. However even with perfectly matched tires the problem on dry surfaces remain the same.

The AWD vehicles are equipped with a third differential that allows for the difference between the rotation of the drive shafts so it can drive on dry pavement no problem. Some configurations allow the AWD to have the transfer case locked which falls into the first category where dry pavement is prohibited.

Some Jeeps have a viscous coupling in the transfer case that permits limited slip between front to rear but the resistance to slip increases as the deference increases as in the event one tire is slipping
These Jeeps still have the lock up option in the transfer case requiring dry pavement when engaged.

Hope this helps?

Center differential


IF you are in constant 4wd then you will not have a centre diff unless you have an AWD. The difference is that AWD transfer cases have a centre diff that allows different road speeds between the front and rear diffs as in going over speed bumps and dips ion the road It is the same operation in the front and rear diffs that allow one wheel to go faster than the other when cornering. However in 4wd drive there is no diff action in the transfer case and both front and rear axles drive at the same speed regardless of speed bumps and dips in the road . This action produces what is known as torque wind up which results in the handling characteristics. This torque wind up places stress on all the drive line train and results in failures such as .that you describe.. This wind up is not noticeable when driving on loose surfaces slippery surfaces or in mud as it is allowed to escape when the wheels spin . If you have an AWD with diff lock capabilities then check that the diff lock is operating correctly

2003 gmc envoy 4x4 problems. 4200 vortec engine. my front diff doesnt seem to be


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.

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.

I would like to upgrade from the present vaccuum 4wd actuator to electric solenoid set up for my 2001 s10 blazer. Who sells this?


There is no electric solenoid set up for the S10's, the upgrade was for the full size SUV's from the early 88 to 98 that had a thermal actuator. There is a mechanical system that is made for the S10's but it requires drilling a hole through your fire wall, running a cable into your cab and mounting the cable lock somewhere under your dash for easy access to lock in your differential.
I had the same problem and i just locked up my front differential all the time, it's been like that now for over 10 years without any issues. The transfer case is not locked up so your front axle is still not synced with your rear axle and is still free to rotate at a different speed then the rear. Just make sure you service the front differential like your suppose to and you should be fine on running with the front differential locked.
Thank you for using fixya and check to make sure that there is no cracks i your vacuum line that is keeping your front actuator from functioning or a failed vacuum switch on top of the transfer case.

4 wheel drive wont engage to front end drive shaft is turning and actuator is moving


acuator at transfer case or at frt diff if acuator is moving then axles to wheels should be turning and you may have a hub locking problem. if axles to wheels dont turn then the acuator tofront diff is no good not strong enough or bent shaft on acuator, some of these use a small shaft in front of actuator also make sure if this truck use this shaft check it for wear, lift truck remove actuator push inside arm in see if wheels spin turn frt shaft while holding arm in wheel should turn is they do, replace actuator, if they dont turn then diff problem,

My 89 chevy s-10 pickup 4 wheel drive doesnt work. the transfer case goes into gear but the front hubs seem like they dont lock in i was told it was a fuse or a vaccuum line but i have never heard of...


On the 1989 s10 it has a vacuum actuator that actually locks the front differential in ,you need to check that first, those go bad real often,and without it. There's no way it will lock in the axle, the transfer case will lock in ,but the front differential uses a actuator. It 's located under the battery tray and there is a cable towards the front of the differential. Id say the actuator cable has gone out, most parts stores can get you one ,that what goes wrong with those 99% of the time and it only takes about 5 minutes to change it out. Good luck but check the vacuum line to the actuator under the battery tray.

4x4 transimission clunks when engaged?


When engaging the 4WD system, you are pulling the lever on the Transfer Case right? Not the transmission, it's a different gearbox.
There were several versions of transfer cases that used both full and part-time 4 wheel drive.
From your description this sounds like a part-time transfer case.
Going with that, it is somewhat normal to hear and feel a mild clunk when engaging 4WD high range, especially if you are at a complete stand-still or under full throttle.
Try engaging 4WD High while slowly rolling at idle - no throttle. It should pull in fairly smoothly.
Once 4WD is engaged it will literally LOCK the front and rear axles together. So do not do it on hard dry pavement.
These older style 4WD systems need a little "give" especially when turning. The engineers assume you are not engaging 4WD unless you are in a somewhat slippery scenario.
Many CV joints, axles, U-Joints, differentials, and transfer cases are damaged and broken by folks who don't understand this.
Reading the owners manual should provide a clearer description of what you've got.
Bear in mind that when you come out of 4WD it may not completely release, again due to hard pavement binding up the axles. You can try this: backing up 10-25 feet in a straight line, or getting one set of wheels on the shoulder or in some gravel. That should allow it to release the transfer case and go back to everyday 2WD high.
I hope this helps.
:)

4x4 will not engage. If front differential is messed up the front end wouldnt move at all correct?-


if the frt axle is vacuum actuated it can be either a broken vac line or the vac switch on the transfer case or the actuator on the axle
