How does the transfer case work in a 4WD?
How does the transfer case work in a 4WD?
Rotating the control actuator to the carious positions changes the clutch torque level. When a differential of front propshaft and rear propshaft speed is recognized, the transfer case control modules commands for more, or less clutch torque. The power flow through the transfer case when in 4WD and low range.
Can you really hear the transfer case grinding noise?
In the first video, you can really hear it start as soon as I put it in gear (@ 5sec), and then I rev up the engine and let off and can really hear it (@ 30sec) – this is how it sounds running down the highway about 50-60mph. I put it into 4WD (@ 1min) just to verify it’s not just doing it in 2WD and it’s doing it in 4WD as well.
Is it possible to transfer data from 2WD to 4WD?
I put it into 4WD (@ 1min) just to verify it’s not just doing it in 2WD and it’s doing it in 4WD as well. Later in the vid I switch it to Auto4WD (about 1:45) and it’s doing it there too. Another angle, I could also feel it by touching the case (@ 25sec) that it was indeed from the transfer case so my ears were not deceiving me.
What does the blinking 4 wheel drive indicator mean?
So what is that 4 wheel drive indicator blinking on your dashboard means? The purpose of the 4 wheel drive light is to indicate when you have engaged 4WD mode by selecting 4H. When the light flashes continuously for more than 30 seconds it signifies there is a problem somewhere on your drivetrain system and that 4WD has not engaged properly.
Why does my transfer case make a grinding noise?
Transfer Case grinding noise – FIXED! Discussion in ‘ Mechanic’s Corner ‘ started by stadt11, May 23, 2010 . My transfer case has started making a horrible grinding noise. First I thought it was coming from the driveshaft or the front/rear diff, but wasn’t sure.
Why does transfer case pop out of 4WD?
As such, some vehicles may exhibit different symptoms. Another common problem is a transfer case that pops out of 4WD. The issue can be attributed to outside influences (e.g., a problem with the differential or driveshaft) or it might be due to an internal transfer case concern.

Where is the encoder motor on a GM transfer case?
Access to datastream information for GM’s NVG 246 system makes most problems simple to locate and diagnose, as our case studies demonstrate. These systems also allow bidirectional control for many outputs. The encoder motor (arrow) is mounted on the front of the transfer case and is used to lock it into 4WD.
