I'm new to forum,
I have a 2002 Chevy Silverado 2500 Standard Cab 2 door ( Not a HD )
My Center support Bearing for my driveshaft is Bad. I have searched continuously for a video that has the support bearing (SB) in the same location and cant find one. My SB is Not hanging like others but it was located above the frame. Is this correct? My truck has ran fine for years until this went and I was wondering if the SB was supposed to be installed below the frame ( appearing to hang). Thanks for everyone's cosideration and help

GM only announced the all new 2020 L5P Duramax and 2020 Silverado/Sierra HD models a few weeks ago and we're already finding out more about them.
This time Gale Banks has his hands on not one, but TWO L5P Duramax engines and takes one of them apart to explain what's different from the 2019 L5P engine. The video is over 13 minutes long but worth every second. Enjoy!
Hi, need help please. Hit black ice in my 03 Sierra 2500 with a duramax engine. Went over a 15 foot embankment and came down hard under front driver side corner which pushed everything up several inches. The motor was running when I shut it down but now will not start. I was thinking maybe an emergency fuel shut off was triggered but now i'm thinking maybe something else. Any ideas or help would be truly appreciated.
PS: jumping them isn't as fun as it looks on tv!
Ok so I have a 99 sierra 2500 4x4 6.0. Parked it last night no problems. Get in this morning back out and put in drive . As I pushed the gas and started straightening the steering wheel the front driver side made a loud pop sound. After that accelerating I had a vibration for a while. Stop and take off no pop but vibration. I drove for about 45 mins vibration went away. I put in 4wd low no issues 4wd hi no issues. Any clues?

GMC's all-new 2020Sierra Heavy Duty will feature more room and amazing towing capabilities. “The all-new 2020 Sierra HD is the most capable heavy-duty truck that we’ve ever offered,” said Duncan Aldred, vice president of Global GMC. “For customers who demand a premium, innovative heavy-duty truck that supports their passions, the next-generation Sierra HD can pull like a pro.”
There is a lot of new and notable capabilities in the 2020 Sierra HD, so we are breaking down the key elements into bullet points.
Here are the 2020 Sierra HD general features. Trailering features come below:
A segment-exclusive available 15-inch-diagonal head-up display that offers useful trailering information, including vehicle speed, navigation information and an inclinometer display for the road grade.
An available segment-first Rear Camera Mirror.
MultiPro, the world’s first six-function tailgate, allows easier loading, unloading and bed access and is available on all trim levels.
A larger, commanding design that provides more room for cargo and occupants.
Best-in-class Crew Cab front headroom and legroom for the driver and other front-row occupants.
An all-new, segment-first, Allison 10-speed automatic transmission mated to the legendary 6.6L Duramax turbo diesel.
2020 Sierra HD Advantages Over Prior Model Include:
A longer wheelbase, a taller, more dominant hood line and taller overall height.
A larger grille and complementing functional hood scoop to feed an advanced cooling system for the Duramax turbo diesel.
Class-leading heavy-duty cargo bed volume and corner tie-downs with a new, available 120-volt power outlet.
One-inch-lower bed lift-in height compared to the 2019 Sierra Heavy Duty, providing easier loading and fifth-wheel and gooseneck trailer hitching.
New, segment-exclusive cargo bed side steps on all box styles, located in front of the rear wheel openings, that complement integrated CornerSteps in the rear bumper to improve access to the cargo area.
World’s first six-function MultiPro tailgate available on all trim levels and standard on SLT, AT4 and Denali.
GMC’s Duramax turbo diesel and new 10-speed Allison automatic transmission pairing will offer superior towing confidence. GMC isn't providing exact specs today, but says that the 2020 Sierra HD will have capabilities well in excess of 30,000 pounds. This is the first HD segment 10-speed. The Duramax 6.6L turbo-diesel engine develops an SAE-certified 445 horsepower and 910 lb-ft of torque.
2020 Sierra HD Trailering Features:
An enhanced ProGrade Trailering system featuring class-leading available 15 camera views, including a segment-first transparent trailer view to virtually see through a trailer in tow.
An available smart trailer designed to integrate the iN∙Command control system from ASA Electronics provides the ability to monitor and control select functions of compatibly equipped trailers through the myGMC mobile app.
Auto Electric Park Brake to automatically apply the parking brake to help maintain truck position when hitching.
All-new Park Grade Hold Assist enhances hill hold by using braking effort at each wheel for an extended period of time.
All-new larger, door-mounted trailering mirrors with a four-bar link providing power extend and retract for the driver and passenger sides.
Integrated trailer brake controller that works with the trailer profile in the Trailering App to recall a specified trailer’s most recent gain setting.
Tow/Haul mode that remains engaged on the next key-on cycle, for up to four hours; includes a reminder the feature is engaged.
Hill Start Assist and Hill Descent Control.
Trailer Sway Control.
Auto Grade Braking and Diesel Exhaust Braking.
Digital Variable Steering Assist that dynamically optimizes power steering according to driving scenarios, including trailering, and enables features like road pull compensation.
Trailering Info Label placed on the driver’s door jamb that clearly calls out the truck’s specific trailering information, including curb weight, GVWR, GCWR, maximum payload, maximum tongue weight and rear GAWR.
When Can You Get One?
The 2020 Sierra HD will go on sale "later this year" in 2500HD and 3500HD dual rear wheel and single rear wheel configurations. Flint Assembly in Flint, Michigan, will be the manufacturing location for the 2020 Sierra Heavy Duty.
