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.
Installed the borla type-s exhaust couple days ago.
build quality is excellent, fitment was absolutely spot on.
took me 5 beers and about 2 hours...
my thoughts.. on the system... also have a type S on my SRT...
1. Cold start is aggressive! It literally barks.... I was very surprised by this, much louder than my SRT system...
2. After engine warms up and rpms settle down it has the very standard s-type deep burble at idle. If the truck is parked and just running, walking behind it is just music to my ears. Very deep little burble that just sounds great.
3. As you ramp up the rpms and roll through the gears, the sound is deep and pronounced, this is the loudest type-s exhaust I’ve heard. Not in a bad way, just know that you will hear this exhaust unless you absolutely butter the throttle and accelerate like an old woman.
4. No drone in 9th or 10th gear.. no goofy noises or vibrations with cylinder deactivation stuff so that’s a major plus.
happy with the purchase, louder than expected but still nothing too crazy. Getting the ATAK version would be overboard for a pickup in my opinion...
engineers at borla said their touring style is identical to the gmc branded perf exhaust in regards to sound output.
so their 3 levels are
type-s - pretty big jump, aggressive! Crazy cold start that barks
atak- crazy man over the top sound, I don’t think many guys would go this extreme
will get better videos soon
Hey guys just wanted to share tis bit of info that I was able to find. It was difficult locating a driveshaft for a 14+ GM 1500 so I hope this helps.
After spending tons of time trying to find a less complicated way to upgrade my DS I visited alldrivelines.com (referral from a member) and saw the 800hp rated 2 piece shaft. I called to verify compatibility and was let down by the rep. It is not user friendly for the 4x4's.
However, after asking me some great questions Shelby @ Alldrivelines (661) 633-2303 simply said why don't you get our 1,200hp rated driveshaft for the 14+ GM 1500.. I said ..."wait huh". Tell me more. This is currently not listed on the website.
It is a 5" 6061 Aluminum shaft with a .125 wall thickness. It is rated for over 1,200 HP and 7,300 ft tq. She can get the correct size for other models too (bespoke).
I'm running the following with a Stock Trans/Transfer Case and ride hight.
Make: GMC Model: Sierra 1500 Denali Drive: AWD/4WD Loc: Rear Bed: 5'9" Chassis: 143.5"WB Doors: 4 Door
After some negotiating it ended up being $580 SHIPPED from CA to MA!!!. (She also suggested the upgraded billet slip yoke rated 1200hp it was an extra $100 so I'm actually $680.00 shipped)**
Just a heads up folks. If you want a Driveshaft that can handle high speeds, high HP and TQ this is the place to go. Call Alldriveline (661) 633-2303 and ask for Shelby. Mention my last name Melaas and they'll cut you the same deal.
A 1,200 hp rated shaft with the billet yolk for $680 shipped. I don't get anything for it I just asked if I could refer my friends here for the same deal and she said sure. Very nice Lady.
Lastly it is a 2-3 day processing and shipping for me (ca - ma) is about 3-4 days. I should have it next Thursday! I will send pics.
PM if you have any questions.

Anyone know what this noise is? It's very intermittent. Seems to do it most often between 40 and 50 MPH cruising with maybe a slight up hill. Never does it on coast or heavy acceleration. Very hard to tell where it's coming from.
