Shake or Vibration Issues

[gbdweller]

There are no words for just how stupid that statement is. I feel really sorry for you if you're so worried about voiding your warranty that you're afraid to torque a few nuts or bolts. Maybe you can't handle such a simple task. Either way, I for one am not worried one bit. Nor am I going to waste 2-3 hrs going to the dealer to have them do it, when it took me less than 5 minutes in my driveway.

That was a pretty messed up comment. I defended myself one time and got threatened by the moderator and yet I see BS like this on here all the time. And if you really stop and think, that warranty being voided theory is not far off. It seems to me like GM is doing everything in their power to avoid making good on these issues so maybe you're the one who is stupid and not the guy who is worried about voiding his warranty.

I am armed with a bunch of knowledge when I go into the dealership this week thanks to this thread but seems like I will be fighting a loosing battle.

I didn't threaten you, this is what my post said. I thought it was a joke and I chuckled a bit at what you said

Lol that's what it seems like

I think you have me confused with someone else. I haven't commented on here in a long time and the warning I got was a long time ago. It was something I was completely innocent in. I saw this other guy's post today about someone being stupid because they are worried about voiding their warranty and it annoyed me because I see useless posts like that on here all the time.

Ah you're right. It was another guy. Sorry about that

Well I'm starting to get annoyed...

Thought vibe at 70mph was tires.

Disappeared for a while(after balancing) but is now back....and balancing isn't fixing it.

F....k

I might have to get them checked again...

First off, I never said that guy is stupid. I said his statement was, there's a difference that you obviously can't see.

 

Second, I firmly stand by what I said. Absolutely no way, one can have their warranty void for torquing a few nuts. Unless of course you're dumb enough to way over torque something like your head bolts and break them off, and them tell them you did so.

 

Maybe you'd do well to read up on the Moss Magnuson Warranty Act. Sure some people have had a dealer "void" their warranty without cause, or having burden of proof. Businesses get away with stuff all the time because people are uninformed. The worst is the insurance business. They only get away with it because people allow it.

Yeah, just the 8 nuts on the u-bolts. They all seemed to go along way before hitting 80.

So when I retourqued mine a month back I did the 59 plus 130 degrees.

 

Since I did not have an exact way to measure 130 degrees, I torqued the bolts to 59, then did a 90 degrees pass, and then another 45 degree pass.

 

That put me at 135 degrees give or take, but it was easier to measure in increments of 45 degrees.

 

So today I took the torque wrench to 80 ft.lbs. and checked each bolt.

 

All of them clicked immediately.

 

So apparently the 59 ft.lbs. Plus 130 degrees is over 80 ft.lbs.

If you have the opportunity, try adding some weight to the bed and see if that vibe changes. I noticed my high speed vibe was diminished when the bed was full of snow. Has me thinking pinion angle. I'm still waiting for a couple things I ordered to see if I'm correct.

 

The primary problem is the trucks are super sensitive. Most vehicles can mask vibrations or harmonics that normally occur. A number of these trucks obviously can't. I think the key to long term happiness is making them less sensitive. However, what works for one may not work for all. I think shocks, pinion angle, and a couple others things may help. Heck, it may take a redesigned driveshaft, if bed weight makes a big difference. I'm also kinda wondering if the air that passes under the truck is somehow inducing something that feels like vibration, but I have nothing to support that, I'm just thinking outside the box on that one.

That's very good to know.... It's quite possible that one could do the 59 plus 130 degrees, and then incrementally increase the torque wrench to find the approximate torque value. I'm a bit perplexed why they wouldn't have a set torque number. Seems like 59 plus 130 degrees would not yield a consistent result due to minor differences in each u-bolt.

GM's Resolution Management Team wants to see proof my truck still vibrates after the 4th and final attempt so I have an appointment scheduled for this Monday (04/11/2016). I requested a buy back directly from GM so we will see if that happens or if we have to go all the way through the Lemon Law process (my truck qualifies under FL Lemon Law, it's been out of service for 30+ days AND 3 repair attempts with the official final repair attempt from GM). Hopefully I'll be able to update you all soon with a good outcome.

You can quote that act all you want. But I am reading about people cranking down bolts without having any clue what the actual torque specifications are. And probably using Walmart or Auto Zone wrenches that aren't calibrated. All while working on vehicles with known problems manufactured by a company who seems to be doing everything they can to dodge the issue. I mean they are blaming rear end vibrations on rain gutters or bug deflectors. Or not driving the vehicles at speeds where the vibrations are occurring because they say that speeds above the limit are illegal and unsafe. So I'll stand by my original defense of the guy who is worried about voiding warranties. Why take a chance and give GM any ammunition at all?

The only ones blaming rain guards and bug deflectors are dealer service departments that are trying to blow someone off because they have no clue what the problem is. In that case you need a NEW service dept.

 

As for the legal posted speed limit, they have the right to deny operating above that. Simply offer to be the driver and let them operate their test equipment. Beyond that, contact GM. GM governs the trucks at 97-1** depending on configuration, which is what they deem to be the maximum safe speed. However the dealer isn't required to break the law.

No it makes no difference....just hauled bike 1000kms....still there.

How much weight?
