got a prob in a 2002 2500HD silverado 4x4 with the 6.0

 

at about 120 km/hr (about 65 mph?) i begin to get a vibration.  this vibration will continue over 120 until i let up on the throttle.  once i have let up the vibration stops, and i can hold speeds over 120 with no vibration. if i drop below 120 and then accelerate once i hit 120 the vibrating begins again.

 

the dealer had no answer.  any ideas?  thanks!

had a look, but i don't think its tires as the vibrating dissapears if i "blip"the throttle...

 

steering seems fine...

 

i've had some people say its the difference between a dual and single drive shaft-the dual gets overloaded...like i know what that means...is this possibly the prob and is it dangerous???

Some people have been able to get GM to replace their 2-piece driveshafts with a one piece.  

 

Personally I would prefer a one-piece drive shaft.  I don't like the extra universal and I definatly don't like having a carrier bearing.  The TSB that refers to changing this driveshaft is "shudder on launch".  I hope I develop this problem so I can get mine changed...

is there an advantage to the dual?  what is the difference, and is it worth getting gm to change? i really don't no much about trucks, so this info is much appreciated! :D

Buddy,

 

The only advantage I see to a 2-piece driveshaft is that it allows the shaft to be tucked up in the frame rails and could prevent damage if offroading.  It also may allow for a thinner driveshaft because all the force of the drivetrain isn't being sent down one "long" tube.  My truck will never see any major offroading and I tow, so I would prefer a heavier one-piece shaft.  I would also like to get rid of the extra U-joint and most definatly the carrier bearing.

You guys need to go to the dealer adn demand a new drive shaft. The ones that vibrate are out of balance. I promise this is your problem.

Get the dealer to replace the driveshaft.... do not buy new tires...

I'd be raising hell if they said they wouldn't do anything on a 30-40k dollar vehicle. Tell them to buy the d**n thing back if they won't fix it...............God people in sales piss me off. (too bad I'm in sales lol)

i have a severe vibration at 70 mph and have brought it to different dealerships and had 3 different gm employees drive my truck with me and they all said it didn't drive normal. i get a call back later saying it's a normal ride(i wasn't in the truck with them) and they won't do anything about it. i can't try to lemon law it because they won't service it.

I would like to give GM 40K for a new Duramax for my business but have driven 5 and they all have this highway shake. makes me crazy. Not buy a dodge crazy, but crazy no less. Is it starnge to start liking my old truck more now that these dmax have dshaft issues? But my 4:10s on the highway drains the tank!

      2026 6.6 L5P oil cooler leaking oil at 4,000 miles

      By Brendan C · Posted

      New to diesel trucks. I happened to find my oil cooler leaking oil externally with only 4,000 miles on the truck. I didn’t realize this was an issue until I started researching it. Dealer is going to replace it under warranty but I’m wondering if there’s anything GM is working on to fix this issue. I’ve heard the oil filter used is the same as they use on their V6 motors and that’s what is causing the problems. Should I switch to a bigger filter or keep using the OEM recommended?

      Seems to be Missing a lot of Updates

      By Vu1can · Posted

      So, GMCustomerService:  Judging by the Update History pictured above, is this truck missing any updates that it actually needs. If it's just for the infotainment system, the radio is working fine and no trouble with SeriusXM. and Android Auto is working fine wirelessly with my phone. Some months ago, an update notice was sent to my truck. I approved the update and it finished saying that the update was successful, but it seems that whatever that update was, it didn't actually get installed - at least not if I'm to go by the Update History shown above.   So, again, are there any updates that this truck really should have? I've checked with my dealer but they're reluctant or commit to anything and if I want them to check, they require a $200.00 fee just to check it out and then I'd have to pay for the actual update(s).    Ignorance is bliss, and if none of the updates goes to fixing any mechanical discrepancies, I'll just leave things as is.

      Electrical Problem - solved

      Hey everyone, I recently had an issue with my 07 2500HD GMT900. My DRL’s stay on at all times. Right front turn and right mirror turn signal indicator stay on solid at all times. By “at all times” I mean the only way to make them go off is disconnecting the battery. I tore the headlight assemblies out, tried disconnecting the harnesses to eliminate bad wiring at the harness, I unplugged the headlight switch, no change and the mirror turn signal still stayed on. My first thoughts were : Bad bulb and/or socket somewhere, under hood fuse panel bad, bcm bad, tail light or trailer wiring problem, or some random short to power in the harness.  Possibly a bad ground but unlikely. I had a big clue in the fuse panel, it had a burnt smell. I started pulling every fuse that had to do with DRL or right turn/park lamp. Nothing made the right directional turn off but pulling the DRL2 fuse made the DRL’s go out.  After studying wiring diagrams, I found that both problems had that fuse panel in common, the bcm also controls both problems but knowing the fuse panel had a burnt smell I removed and disassembled the fuse panel and found a little corrosion on the printed circuit board.  I ordered a new fuse panel from Amazon for like $260. When it arrived I installed it, and put everything back together, the problem was fixed. I figured the fuse panel needed to be replaced anyway so that was a logical place to start. Hopefully this story helps someone in the future. Regretfully I didn’t scan for codes before I did everything.

      That stinks. I’m sitting on the side of the road right now with the same issue. Never had an issue before taking it in for the ground strap recall. Now I’m outside of warranty and they’ll probably want $200 just to diagnose what they already “fixed”.
