The reprogramming is the cheapest way for GM to be the 'Good Guy." GM will have a lawsuit 'kitty' put aside when folks gets killed for brake failures and pay out from that. This method is less expensive than doing the right thing. It's no different than the drug companies when they come out with a new wonder drug. They put $500,000,000 or more aside to cover lawsuits that we see advertised by the attorneys on TV but they still make a couple billion dollars profit just the same. This is similar to GM's solution.

Goodyear SRA's My truck came with the 20" chrome wheels and Continentals. Three months after taking possession of it I bought a full set of the ZR71 aluminum wheels from a dealer who installs lift kits, I don't like the chrome wheels. Being concious of the vibration problem I had my independent tire place balance the factory 18" Goodyears. Before they started I asked the owner 'How good is the factory balance' and he said "Usually pretty good." The balance was NOT a road force but a conventional balance: Two wheels took 2.5 oz, one wheels took 1.25oz and the last wheel was OK. Two and a half ounces is a LOT. So off I went after spending $50 for my own satisfaction and it was probably a good thing I did. I have had no issues with the factory Z71 18" Goodyear SRA tires whatsoever. They have been to Florida and Alabama with no vibrations whatsoever on the 70+ MPH Interstates and my truck didn't have any vibrations with the 20" chrome either. These last few pages have brought another factor into this whole 'road force' and tire balance/vibration issue: How competent and how well trained are the dealer techs using the machine? It's not nuclear physics to use one but it does take some practice and training. Does the dealer even HAVE a machine when they claim they did a 'road force' balance. Has everyone SEEN the machine at their dealer's when they claim a 'road force' balance was done?

You mean the truck, right!

It's been stated numerous times in this long thread that many who have replaced their driveshaft still have the problem. What fixes your truck may not fix another's.

Barak, I made no reference to 'road force balancing,' my reference was to the PICO tester and its available printout. Your experience with those Goodyear Wranglers is another example of what may solve one owner's issues and not anothers. When I bought my truck I removed the 20" chrome wheels and installed the default 18" Z71 aluminum wheels with those Goodyear Wranglers. I never had a vibration then and don't have one now and those wheels and tires carried us to Florida once and Alabama twice on the 70MPH+ Interstates. I've seen many complaints about the Wrangler tires here but I never had any issues with them. I've had the 18" wheels conventionally balanced independently by a private shop after the exchange, not a road force balance, and the factory balance left a lot to be desired. I personally have no idea what causes the vibration on a small percentage of these GM trucks but it's a helluva thing to read about the problem on $50,000 +/- trucks and the understandable dissatisfaction of those owners.

PICO tests provide valid legal and diagnostic summaries and can be used in related or unrelated court cases. Not able to print a summary is pure bullshit so you're already being lied to. Perhaps the PICO tester they borrowed conveniently can't print.....

Guys, Some of you have not been here long enough to read some of the hundreds of other posts regarding 'vibrations' and no one expects you to start at the beginning of this thread either. 1. There are many, many examples of driveshafts being replaced with another GM driveshaft that have not cured the problem so don't be disappointed if that's not your fix or they tell you "The driveshaft runout is withing tolerance." 2. There are many, many examples of engineers coming to the dealership to pay lip service and state '"It's within GM specs." 3. There are many, many examples of the dealer performing the PICO tests and stating "It's within specs." 4. What cures another owner's trruck will not necessarily cure your truck with the same fix. It might but don't be disappointed if it doesn't. 5. There are many, many guys who bought quality aftermarket parts including driveshafts, rear axles, etc. Some had their problem fixed that way and some didn't. So to summarize, what fixes one owner's truck may not fix yours so be prepared to either be very disappointed or very satisfied. Being disappointed has been in the vast majority of GM dealer fixes. GM knows what the problem is but they won't admit to it.

You were aware of the Silverado vibration issues, you took one out for a test with the salesman and the truck vibrated, and you bought it anyhow Why??

Myron, You look like a proud new father!

I ripped off the 275x55x20 OEM chromes and exchanged for a set of Z71 OEM 265x65x18." Nice quiet ride on the interstates, doesn't feel or ride like an Abrams tank, good gas mileage. Keeps up with a 6.2 running 35's big knobbys with wide offsets. My 'off-road,' like most here, is riding on the shoulder from time to time.

Can someone describe how to "Untag" a singer for the radio? I accidentally 'Tagged' a performer and every time she appears I get the notice.

Do a search here for the Bak covers fitting flush to the top rail. There has been quite a few leaking issues with them. Look above at bkesting's red truck with the Access Lorado cover, it's a classy one.

Try squirting a little silicone spray in the folding crevices from time to time.

Now that looks nice with the OEM wheels. Some of the 'problems' seen here result from installing 'macho' big wheels and tires that change the geometry of the front suspension and ruin ball joints. Hope you keep your OEM wheels!

There are numerous posts here telling of leaky Bak-flip tonneau covers. To be fair they make quite a few different models so this may not pertain to all of them but for the price they charge there shouldn't be any leaks. See what you can find doing a "Search" in this thread. PS: Nice looking 2018!

No more of a sin than to put Chinese communist wheels on an American truck assembled in the USA.

Is that the reason you joined this forum? To piss and moan for one post?

A word of Caution: Donations Not Charitable: “Under US Federal tax law if you are not a registered tax-exempt charity and you "ask" or solicit in any way (eg. Paypal Donate button, Facebook, etc.) for a donation, then you MUST put a clearly worded statement indicating that you are not a registered charity AND that ANY and ALL donations made to you are NOT tax deductible. Failure to display this statement is going to get you into big trouble if someone gives you a sizable donation and then lists you as the "charity" on his/her Federal income tax form and gets audited. The IRS has taken the view in the past that when a person "sees" the word “donation,” then that person "assumes" that he or she can list it as a deduction on their tax returns. Also any "donations" received by you are fully taxable at the federal level and possibly at the state level as "ordinary income." In other words, it is income that has to be reported on your tax return under form W-99 misc. income."

Actually GM really isn't so 'stupid,' they aren't issuing a service bulletin to fix the problem because whatever it is, it's going to be expensive. They dropped it all on truck owners and their dealers. I don't think that's 'stupid' at all. And don't think for a moment that GM doesn't know what the problem is, they know............

He wouldn't do well in federal prison.................

Finally a black truck owner that exhibits some contrast with his wheels. From 20 feet away black wheels look all the same: Black
