Shudder on takeoff

[kyle3450rl]

My 2011 GM D/A CC 4WD DRW has a shudder on a brisk takeoff from a stop pulling my 3450 RL. Dealer thinks it might be my Cardinal. Truck and camper 27,400 lbs. Anyone else had this issue w/ newer GM ? I am sure it is not my camper. Thanks for any input.

Lots of long wheel base trucks have this drive line problem. It is a result of angles in the u-joints and center carrier bearing. There are a lot of TSB's on the subject. On my buddies 2000-01 Chevy they replaced the two piece drive line with a single aluminum one years ago.

Dodge has had this issue also.

If your truck is squatting a lot you might think about air bags, as the more it squats the more the angles are changed.

And quit racing Fords from the stop lights. All test show you are faster!

Nope not your Cardinal well other then the weight/pin weight. All my Dodges and both my Chevy trucks did this. It is the angle of the driveline. You can have it shimmed to not do this while towing but then you get it while empty. I notice in my case if I put about 1/3 of a tank of fresh water in the shudder is much less do to less pin weight. Ease off the line until the truck is rolling, lots of strain there so I wait until it shifts to 2nd before I start pushing harder on the go pedal.

Chris hit the submit button faster then I did.

I had the same problem with my '09 F350 "Tow Boss" CC LWB dually. Not as much with the '12.

I don't race off the line, just pull mountain grades at 65. "I CAN'T Drive 55!"

^^^ He just needs a heavier trailer! 30 footer is to light for his new Ford! What was that old Navy story about having to be able to ride a bike to become a chief???

I don't know about a bike, hard to ride one on a ship. But having an operation on your finger to hang onto a coffee cup while asleep...

With 3:73 gears the F350 duallys do get off the line faster then the SRW F350's though. And still get 12 mpg average towing a 5er in my experiance.

Hard to tell you that something is normal, but my 2011 GMC CC 4WD DRW once in while has a shudder at take off.
You have a heavy trailer that hard to get move, I will only feel this if I try put take off too fast from a dead stop, my Ford also did the same thing.
Try what all others are saying about take it easy until you are rolling a little.

[WVcampers]

No shudder here. just have to be easy on the throttle to prevent wheel spin

[Olbird]

It's all about size and weight, hook up to a beast 38 feet and longer loaded and take off hard and you will see all these trucks will shuttle.
The rear axle housing is trying to twist with all the toque being applied to drive shafts, that's why they use double drive shafts and u-joints.

I had a pretty good shudder with my Dodge which was totally eliminated when I added my airbags.

Hey Kevin, are you still driving the truck in your signature? I thought you bought a newer truck.

With the price of new trucks....I'll be driving this one for a long, long time. I've only got 70k on it and it pulls like a beast while usually getting around 14 mpg. They say these Cummins will go for a couple hundred thousand and since I have the 6 speed manual tranny I figure the worst thing will probably be a new clutch. Keeping my fingers crossed.

[Rob & Cathy]

Sounds like a good plan.

The body will go, before the motor................Just under 300,000 on mine.....runs fine. They need to come up with a variable angle shaft, rear end combo....to auto adjust to load..... ..........................and survive the torque.!!!..
