1. broken 4WD shift linkage 2. hubs not locked 3. hubs not locking (vaccume leak) I have a 96 blazer and the vacuum actuator, located below the battery tray, had a vacuum line disconnected. I have had several friends who had their actuator go bad. The acuators were actually a recall they have since replaced them with a newer and better model they usually went bad if not used for a number of years.
Also check the vacuum switch on transfer case as it has a check ball and can sieze up $15.00-$20.00 part. these are usually the first to go and if left to long the Vacuum actuator Abt.$50.00 can collect fluid and disentegrate, they also just go bad.The encoder motor is a solenoid Abt. $200.00 part and can sieze up as well, these are prices from a store like Auto Zone and are not from GM and do not include labor. I have learned that you need to use your 4X4 on a regular basis when you have electronic push button. I engage my 4X4 going down dirt roads and sometimes down rocky or dirt driveways. This helps keep the parts freed up and working.
rear wheel drive or 4x4 capable
i have a 1989 chevy blazer gos in 4x4 drive but front wheels are not pulling wat do i do about that
It is rear wheel drive, until you shift it into 4 wheel drive.
I have a leak on my drive shaft left front 2000 cheve Blazer I would like to replace the whole unit
you dont, if you want to disconnect it then remove your front drive shaft.
2 wheel drive, yes. 4 wheel drive, no.
In the front
NO, It is all different. Won't work.
It could be the shift motor on the T Case. Or it could be the automatic shift button switch on the dash.
tAKE THE FRONT DRIVE SHAFT LOOSE AND SEE IF IT STILL DOES IT IF IT DOES ITS THE FRONT CARRIER ASSEMBLY IF IT DONT ITS THE TRANSFERCASE
