transfer case

While attempting to fix a problem with the truck randomly shifting into4WD, I think I broke it. I pulled the encoder motor, front driveshaft, front actuator to test the motors. I believe I failed to align the encoder motor and transfer case to neutral when I put things back together. When I...

My 98 sonoma high rider decided it doesn't want to engage its 4x4 for me anymore. When I hit the button I hear a click noise. Not sure what the click does but I don't think it's the hubs locking. I checked my actuator to see if it was functioning properly and it was. I hit the 4x4 button and had...

1990 GMC Suburban 1500 350 CI Automatic transmission (700 something?) i am almost certain my 4x4 won't disengage. the actuator seems to work fine, and i followed the instructions in the owner's manual that states i need to reverse direction for approximately 10ft. after shifting back into...

My 2006 Sierra recently started giving me some trouble with the 4wd system. It was taking multiple attempts to get it to go into 4H and the service 4wd msg would display. After it did this for a period of time, it would not switch into 4H at all and only went into AWD and would not shift out...

hello all and happy new year! i have a 1990 GMC SUBURBAN SLE V1500 4x4 with about 342K on the body 350 with the 4 speed auto transmission recently while i was driving it, i would hear a loud popping-type sound while coming out of a 90 degree turn at relatively low speed. this...

I purchased my '98 Jimmy in 2012 with 148,000 miles. The previous owner had unplugged the 4x4 switch and when I plugged it in I figured out why. The front wheels engage in four wheel drive quite smoothly in both 4Hi and 4Lo. The issue is when I turn either direction there is a nasty...

Ive got a 2005 GMC sierra with about 58,000 miles on it. when i got in to leave it was in 4wd and wouldnt go in 2wd until i started moving and when i stopped to take off it wouldnt pull until i put it back in 4wd. and now it wont go in 2wd at all. im gonna check a few things but i dont have much...

Here is a tricky one for you mechanics out there. I have an 03 with the three button transfer case selector switch. The problem is when I go to shift into 4wd, be it either low range or high, the transfer case shifts but the front driveshaft will not spin at all. I put it up on jacks the...

When going into reverse I heard a loud bang then my car stopped going into reverse. its as if the back tires are locked. you can push hard on the gas and it will move but it makes a loud noise and jumps backwards. So it shifts into reverse but doesn't want to move. it also makes the noise when...
