How To Remove/Install Driveshaft.

[DenaliX14]

Hey All, 

 

I've had a lot of folks ask me about installing my new driveshaft. I will link the thread for the high HP driveshaft. Here is how to remove and install a driveshaft for GM 1500 Trucks. Hope this helps.

 

1. Raise the rear of the vehicle and support it securely on jack stands and block the front wheels. Or use a lift. 

2. Place the transmission in Neutral with the parking break OFF.

3. Important** Make a reference mark on the driveshaft and the Pinion flange (if keeping original driveshaft) in line with each other. 

 

 

4. Remove the rear universal joint bolts and retainers. Rotate the shaft in the most convenient way as to not allow the shaft to spin. Try inserting a screwdriver in the shaft yoke to keep the shaft steady.

 

5.For Two piece shafts remove the fasteners from the center support bearing. 

 

6. On ALL models, tape the bearing caps to the universal join to prevent the caps from coming off during removal 

 

7. Lower the rear of the shaft and slide the front of the shaft out of the transmission or transfer case. 

 

8. cover the transfer case or transmission with plastic wrap or plastic bag to decrease fluid loss or contamination.  DONE!!

 

Installation

 

1. Assuming the oil seal is in good shape slide the front of the driveshaft into the transmission or transfer case.

 

1.2. On models with two piece shafts raise the center support bearing into position, install the fasteners and torque to 30 FT-Lbs

 

2. Raise the rear of the drive shaft into position (make sure to align your marks if reusing your current shaft), install the fasteners and tighten to 18 ft-lbs

 

3. Install the clamps and bolts. Tighten all bolts to 18 ft-lbs.  

 

**FYI The yoke bolts are 118 ft-lbs. 

 

Here is a video from youtube that may help too.
