01 GMC Jimmy R & R TCCM

Ive done tons an really didnt have any probs that I can remember, you can always pull the shaft only five minutes, the job only calls fo.9 hrs, I am having a brain malfunction a the moment will egt back to you in the morning

, have some faith in yourself, as a tech of 20yrs I have alot of tools and may have had made or bought a wrench to fitbut I dont think so, before you do pull the shaft look at the bolt really hard and make sure nothing will fit, wait are you looking at the right part, the encoder motor is on the left side of the transfer case, the only thing even close to the driveshaft is the motor housing which has no bolts, yours should have three bolts on the side, maybe im thinking you meant the torsion bar, I did one a few weeks back on a 99 same thing and it was out and in, in approx 15 minutes, let me know what you think and find
i was also sitting here wondering what exactly led you to the encoder motor? Usually when they go outthey will still make noise but not switch gears, I have pulled them apart and found out why, but if you have a different scenario let me knowyou are calling the encoder motor atccm, the tccm is the computer that controls the motor via the switch on the dash, I just want to make sure you are replacing the right part if you wouldnt mind telling me what happened

This is the encoder motor

This is the tccm

You will need some help, have someone get in the truck turn the key and start hitting buttons while you check the encoder motor for noise, it should make some if just the motor is bad, aldo check the switch when the lights come on and look for a breif red light on the switch, here is how it works, when you turn the key the tccm cyles and blinks the lights on the switch, when you hit a button the signal goes through the switch to the tccm, and then to the encoder motor and on to the front diff switch telling it to lock the axles in,

check that and get back to me, these things are hard to diagnose sometimes and every part I spoke of goes bad on these trucks the switch is #1 the encoder mtr is #2 and the tccm is well known for failure
if you had a test light you could do the test above and pull the harness going into the encoder and check for power while the switches were being pushed, test light is a goo and inexpensive tool all beginners must have
let me know

Ok thanks
