I've posted a couple threads on this before and thanks to you guys who responded.

I bought my truck in July, brand new dually with all options, discovered a 37-42 mph vibration on day 2 that would not go away no matter what the dealer did. The truck never responded to frame beaming fixes...extra weight, or any repairs attempted, just produced every time a persistant resonant type vibrations.

Tires were balanced, road forced, replaced, driveshaft was sent out for balancing, exhaust dampers were installed, then frederico's anti sway bars were attached...all to no avail.

It's been in for repair pretty much wheneve I could find time to take it back down there, but I travel a lot, so somethimes it was weeks between the next attempt at repair. NOTHING even touched teh vibration.

After 9 months, 25000 miles, and nine trips to the shop to try whatever they could come up with, usually with me researching and suggesting the next repair on sites like this, I tried another dealer, who immediately drove it, felt it, declared he could fix it, but then backed off when he saw the service record in the GM system, and said I should take it back to the original dealer for various reasons, so I did, but told them that's it, you can have it as long as you need it, I'll be in and out of town for two weeks and have very little extra time so call me if you get it done, otherwise, let me take it to this other dealer if you can't figure it out. Two weeks go by, I stop in, and I see he has an identical one pulled up to the shop, and informs me, he's called the other dealer, has some ideas, he's going to test drive the other truck, virtually identical dually, and if it doesn't do what mine does, he'll start swapping parts. Two more days, today, I get a call, vibration is gone. I am going to pick it up tomorrow AM, will verify then.

"We can't put it on paper" but we swapped the driveshaft. Now the other truck has a little vibration, not as bad as mine (new truck? I don't know, don't care but feel sorry for whoever gets it) but anyway, they swear mine is fixed.

I didn't mention the number of days it's spent in the shop. It's on all the tickets, I could count them but why, it's well over 30 - probably 45 for this one repair if you count all the trips, many times they had it a week or so. Also two computers have been replaced since the engine clock would just reset itself on it's own accord, after 25K miles, it had 1.9 hours on it. Altogether it's been in the shop ten times.

Should I accept my truck back without something written on the ticket as to what they did to fix it? All I have now are tickets for oil and fuel filter changes, and the same complaint on every reciept. If I were to try to sell it, I can't exactly show all these receipts with my complaints and no apparent repair.... they just said tell 'em we swapped a tire.

In the beginning I was satisfied with their willingness to keep trying to fix something that started as a minor vibration but now I'm pretty disgusted with the whitewash, I hate dishonesty, I was ready to lemon law this otherwise sweet truck, and now I feel like they're just trying to avoid that situation if I have another malfunction of some type....besides, who knows who gets that other driveshaft?

I should just be happy it's fixed, (if it's fixed) but it bugs me that it took them so long to find something so simple, they supposedly balanced the driveshaft before, after all, and really, disgusted is the only word that comes to mind.

Are they really just trying to avoid admitting in writing it was ever really broken, and what should I do about this, if anything?

They are probably trying to save their own butt and keep GM from seeing it. I doubt that corprate would be happy about swapping parts from vehicle stock. At least it's all fixed now.

i would suggest all the proper documentation. The only person that can be screwed here is you and the screwing will come down the road when you try to have work done or are selling it, basically a very inconvenient time. With all documentation, the responsibility rests with the dealer and not you.

What happens when one of the parts they swapped fails and breaks something else. They can deny they ever swapped anything and then you'd be screwed. I would talk to whoever you need to for the proper documentation. just insurance for you.

And hence the word STEALER Comes to my mind once again.

What ever happened to CUSTOMER SERVICE and doing the right thing.
Good luck with it, and try to get something in writting, and call the customer support line and tell them what is going on there, or maybe you should threaten with it first, then if you do not get the answer you were looking for, CALL them right there in front of the dealer. Print out all of your threads from here, and write down dates and times and what the conversations entailed, the more together you look to have your **** the better.

Like the movie American Grafetti, when Richard Dryfuss Scratch Gill Favors hood and the Pharoe's Car club got him, "It's not the scratch, it's the priciple"

I went thru the exact same thing but with my steering box... They didn't document it anywhere. Now some poor sucker has my remanufactured box in a brand new truck and has no idea. They dealer traded it two weeks after taking it's steering box and putting a crappy reman'd on it...
Now I've got a vibration that wasn't there until they replaced my carrier bearing, put new tubes on my driveshaft and replaced all the Ujoints. Dealer is saying they want to have my truck so they can shimm it up. Funny how it didn't need shimming or have a 20mph shutter before they messed with it. They wanted to try another driveline but didn't have another truck on the lot that matched my truck...
