GMC Jimmy transfer case encoder motor install 97
I am about to replace the transfer case encoder motor on my 1998 GMC Jimmy NP1.
I have the typical engage 4x4 problem: I disconnect TCCM or unplug battery for a few minutes,
turn on/off the ignition 5 times and then works for a little while and then no more.
I have replaced the
vacuum actuator (new)
front axle coupler sensor (new)
TCCM (junk yard)
dash switch (junk yard)
in the above order; so now
I have acquired a new transfer case encoder motor and about to install it. I read a post in another
news group that says:
***HOW TO INSTALL THE NEW ENCODER MOTOR***
Lucky way - Only thing that needs to be removed is the encoder motor itself. Tools needed are a
10mm hand wrench and a 8mm and 10mm socket wrench. The 10mm socket will work on the
upper and lower bolts, while the regular wrench is needed for the middle bolt. (Tight squeeze).
The 8mm socket is for the electric plug.
Then, just pull out, and wiggle it out of the truck. Install in reverse order.
Unlucky way - This means the encoder motor did not just wiggle out. Now the front drive shaft
will have to be removed at the transfer case. Then, a yolk puller is needed in order to remove
the yolk from the transfer case. Once this is done, go to the directions in lucky way.
The above process was for a 1997; does it still apply to 1998?
Are there any secrets to this process?
Can I influence the lucky/un-lucky way?
Tanx in advance.
