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!!
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.
Here is my post about an upgraded driveshaft, 1,200 Hp and 8,300 torque.
I have a grant steering wheel assembly, but I need more insight on how to install. Watched a bunch of videos but couldn't find a good one for what I doing.

I just got a 2017 Sierra SLT over the weekend with a 6.2l engine and 8-Speed Tranny. 85,000 Miles
The previous owner had done the following that I can tell from Carfax and looking around:
-MBRP Full Exhaust system
-Catch can setup
-Heads taken off and gaskets replaced (Per carfax)
-Differential Fluid changed
-Differential Cover changed
I am trying to read up on everything about it and I had some questions that may be obvious or simple but I am having a hard time finding the answers to.
1.Im not entirely sure if the truck has a tune or not.Is there a good way to tell?
2.Would a custom tune disable AFM?
3.Do I empty the Catch can often?
4.Should I do the TSB 8 Speed fluid change at its current miles? Or is it too late?
5.Any advice/ info to a new 6.2l anyone has? Im wanting to know as much as I can.
I am looking for this truck to be a 15 year truck. So maintenance and must do's are very important to me.
Thanks for any help!
Greetings. New guy here, so please freely call me out an any forum missteps.
I started out with a base model 2018 GMC Sierra 4wd, regular cab, standard bed. It has a snow plow package and 3.42 gears. Onyx Black. No frills. I'll try and remember the order in which I did everything. All work do date has been done in my driveway, which I'm reasonably proud of because I work a job where I mostly send emails and sit in meetings.
-- Debadging happened the first day of ownership... just my thing, costs nothing.
-- Blacked out my front badge with with plasti dip
-- Removed the air dam
-- Cover King carpeted dash mat added, in the color of 'wine'.
-- Cover King saddle blanket seat covers added in wine/whiteish.... returned after about a month because they were coming apart at the seams in a quite literal sense. Back to my grey cloth seats.
-- Added a Rough Country 2 inch level (those cheap spacer things that are shaped like 'C'
-- Brow tint on the windshield and multiple layers of Collinite way done by Motoring Images in Lee NH (ok, this wasn't in my driveway)
-- Airaid modular intake and filter added. Sounds great, I'm a fan.
-- Borla ATAK cat back system with polished tips. Sounds wonderful.
-- Diablo Intune3 handheld tuner, custom (non dyno, remote) tuned further for 91+ and some extra oomph by Lew.
-- Mudflaps installed and ultimately removed because they were the no drill kind and drilling would have helped from losing one in a carwash or who knows where, so those are gone.
