I have a 02 Avalanche. It seems the 4wd drive does not engage. I have checked the transfer case actuator and the front diif actuator. They are operating normally. I have raised the left side of the truck so the wheels will be free rolling when in neutral. Then I rotated the front tire to see if the drive shafts where turning normally. I then engaged the 4high which activated the actuators. The front and rear axles were locked together. This should should show that the transfer case is working an

2000 GMC Yukon 4WD. Has a whining sound coming from the front end when driving. Gets louder as you accelerate. Checked the transfer case and it is fine. Someone told me it could be the Actuator on the transfer case but unsure. Removed front drive shaft and problem goes away. Binds up in 4WD. Please help?

I have a 2006 silverado and I installed an engine and wiring harness out of a 2003 silverado, along with a new transmission and transfer case. The cruise control, and 4wd do not work now. The "service 4wd" light is displayed and I dont know what to check, It sounds like the transfer case if shifting when I push the button but the front actuator is not switching.

I just switched out the transfer case (NP 241 C) and It still wont go into 4wd. The vacum line to the transfer case is capped off and always has been. the only thing left is the transfer case switch or the actuator. Can I remove the acctuator fron the diferential and check to see if its working ok or does it ground to the diferential?
Just replace the actuator in the front differential, they commonly go bad, I hope you needed the transfer case anyway. ... 1989 Chevrolet Silverado 2500
I have a 2001 GMC Sierra Pickup that has electronic 4WD that will not engage. If you press the buttons to enter from 2HI to 4HI, 4LO, Etc. the choice of the button changes (lights up) but the truck does not have 4WD engaging or working? I have checked fuses, and they are fine. Could it most likely be the actuator? I am not a mechanic, would it be the transfer case actuator or the front axle actuator? Thanks!

My 01 Trooper had problems with the TOD starting last winter. When the switch on the dash is engaged the TOD indicator flashes continually at 4hz but the check lite does not come on. I have vacuum at the actuator but no way to measure it. I locked the actuator in the 4wd position using a 10mm bolt as described in one of the 4wd forums. I have manual hubs installed also. My problem now is that the transfer case is apparently turning in the 2wd mode. The TOD indicator blinks no matter what 4wd mod
We have a 1998 Trooper that had the same problem. The fix was an electronic switch for the 4WD - a vacuum sensor - on the front axle that just plugs in. You can see it - if you look under the car from the front, it's mounted in the middle of the fr ... 1998 Isuzu Trooper

Sure sounds like the vacuum switch is not working properly. You have done exactly what I would have done, start with the actuator(most common problem) and go from there. If your not getting the vacuum , then most likely the vacuum switch is your prob ... 1997 GMC Sonoma

I have a 2000 Chevy Silverado 1500 5.3L engine, automatic transmission, automatic transfer case. It has the push button 4wd system. My service 4wd light is on, and i cant figure out what the problem is. I read that the transfer case control switch will often go out and cause this, so i replaced it. no luck. I rebuilt my front differential to find two pitted bearings, meanwhile i replaced the actuator. still no luck. Then i decided it must be the transfer case control motor, which mounts t
Hello rwells.The transfer case shift motor is the usual suspect in most 4x4 engagement failures.Inside the shift motor there is a position sensor that signals the module where it is.Because this is a digital signal it can get "confu ... 2000 Chevrolet Silverado 1500

I have a 2000 chevy silverado 2500. It has the 6.0.The truck has a manual shift transfer case instead of the push buttons. The 4wd used to work fine but now it doesn't. The transfer case goes into 4wd but the front axle isn't engaging. I already replaced the actuator twice actually because I thought I recieved a faulty one from the parts store. The 4wd light on gauge cluster stays on a lot but not the service 4wd. I need to know where it recieves voltage from. I need any help I can get please!!

4wd grinding When I engage the 4wd, there is a grinding noise goin down the street. Also the truck sways from side 2 side. I jacked the truck up and there was no noise. I've been told to check the transfer case oil for color and metal shavings. I plan to when the weather cooperates. It's not a wheel bearing. Is there anything other than something in the transfer case that could be wrong?

How do I definitively tell if my 2000 Ford Explorer is stuck in 4 wheel drive? This truck has Control Trac automatic transfer case with 4L V6 OHV eng., NOT AWD. No 4WD indicator lights on dash. No one seems to knows this. I paid a Ford dealer to diagnose it, and they told me the Transfer Case Shift Motor was bad, so I changed it. I am now about 90% sure that this could not have been the problem; motor only controls Hi/Lo range. Any information would be appreciated.
Try jacking up both ends. Start the engine and watch the wheels spin at idle speed. If they all turn at the same rate, you're in 4WD.The other way may be more fun. Have somebody watch while you drive through a mud hole. If both wheels sli ... 1999 Ford Ranger SuperCab
1999 NBS Z71, transfer case will not shift with push buttons, build code NP8, shifted to 4HI got a SERVICE 4WD light but went away and the truck completed the shift to 4HI. When I went to shift back to 2HI it would not shift, it would shift 4HI to Auto 4WD. Have changed the selector switch in the dash, repair shop told me the transfer case actuator motor was bad, I changed that- now the TC will not shift out of NEUTRAL. The TC feels fine when shifting with wrench- Question: how many positions

My 1999 Tahoe (odo reading 137,400 miles) won't go into 4 wheel drive. A couple of days ago the "Check 4WD" light came on for a while and then went off. I planned, but haven't done so yet, to get all the fluid levels checked this weekend. But now I see the red "Neutral" light is lit and I can't engage 4 wheel drive. If there is a low fluid level sensor, can low transfer case or front diff lube cause this? Also, the problem may be a blown ATC fuse for the transfer case, but my owner's manual does

I have a two pin plug hanging adjacent to the transfer case on my 1992 Ford Explorer 4WD. It is grouped within the harness which goes to the transfer case. The 4WD operates as advertised. Any idea where it should terminate? I don't see a recepticle.
If everything is working okay like the 4x4 light comes on when put in 4x4 then it maybe an extra plug that the factory uses on a model with more options. so instead of making different harness's they make one that works in many applications. ... Ford Explorer Sport
4x4 Problems I have a 99 GMC Jimmy with push button 4x4. Placing the car in nutral followed by pressing the button it doesn't flash like it used to just lights up the next setup 4x4 hi. You can hear the transfer case locking in but front tires don't move. The transfer case is getting vaccuum. Drive shaft going to front axle does spin. The Vaccuum actuator under the battery tray is working normal no cuts or anything. Also cable from vaccuum line is not broken. Did check to make sure the actuator

1990 ford f150 won't shift into overdrive and has constant high whining sound while in motion. Problem came on suddenly 2 days ago. Recently I changed rear drive u-joints and muffler, should be no connection there and had transmission fluid and filter changed yesterday. A few weeks ago transfer case was low on fluid and I filled it and replaced rear output seal from transfer case. I had mechanic to do quick check on differential for excessive slop at the wheels but he said it was fine.
Sounds like your front hubs are staying engaged, lots of problems with them on Fords, there should be a vacumm solenoid next to the battery, follow the lines down to the wheels and check for leaks. If you have a vacuum guage you can plug the line at ... 2001 Ford F150 Styleside SuperCrew
