Thanks guys, I was leaning toward the bearing because the ac works fine. It does look like it will be quite the project to get it apart.

I have an 02 Bravada that is making a sound under the hood. Sounds like a wobbling air compressor. It makes the sound when the a/c is off and the engine is at lower rpm. As soon as I turn the a/c on and the clutch locks up it stops. Also all pulleys are tight except the power steering , it has...

Just an update guys. I installed a new encoder motor on my bravada, which was a piece of cake, and still no awd. Then "bing" the lightbulb came on, pulled the atc fuse for 30 sec or so and tried again, AWD works perfectly. Thanks for the help guys. This site and its resources are a lifesaver.

Hey guys I have another question to put out there. I have a 2002 bravada with 100k and it makes a periodic rattling/vibration under the hood, only noticed it at idle and before the engine is warm. It sounds like an pump with the line piched off. Only does it for 5 seconds at a time and only...

Looking to buy a scan tool guys. Whats the best one I can get for 3-4 hundred bucks? I would like to be able to read a-b-c codes, monitor transmission and check sensors if thats possible without investing $2000.

jeffro- from what I can gather from the wiring diagram I downloaded 12v should ignite some sort of movement in the motor. I tried every combination of pins possible and never got anything. and like i said pull the cover on the motor and that may tell the whole story. It did for me anyway.

Im new tothis platform but have been fighting the exact same problem in GM trucks for several years. The TB and trucks have VERY similar 4x4 systems. I would take apart the connections to 4x4 switch, encoder, and axle actuator check their condition. Then use a contact cleaner and give em some...

Thanks for the input! I havent done anything yet as far as major over hauling goes and I was going to change it atleast one more time anyway because it seemed to make sense. Also I removed my encoder motor the other day to do a bench test. I couldn't get it to do anything. Took the cover off the...

Thanks again roadie! I will report back when I get this ordeal figured out.

Thanks c-ya

I have an 02 Bravada that has np 126 transfer case. 4x4 not working. Narrowed the problem down to the clutches being smoked or the solenoid that engages them. I can't find much info or even kits for this transfer case so I came te best place I could think of so any help would be much appreciated.

I am having the same issue. I put mine up on four jack stands so all wheels are off the ground, then started it up and put it in gear. At first the rear wheels spin only then at about 30mph the front engaged. I got out and applied pressure with a 2x4 and was able to stop the wheels. To me this...

If I could just hook up a toggle switch and go I would. Given the 126 is a single speed tc its either in or out of gear and as I understand the cluches are applied in varying amounts depending on speed. So in theory if I could get the clutch pack situation figured out an on/off switch would...

Hey guys. New here to GMT. Just got a 2002 Bravada a few days ago. I had no awd, did lots of research and found I needed to change tcase fluid before I did much at all so I did. The old fluid came out blue, looked clean and free of foreign material and looked to be proper amount. Replaced with...
