Anybody else here have a hood that bounces a lot in windy conditions?

It almost looks like its bending and I'm expecting some day its just going to fly open. Never seen a hood do this.

Have you tried adjusting the bump stops?

I'll have a look this weekend.

I think the hood is aluminum right? Its going to flex more than a traditional hood. Mine does it slightly but not that noticeable. One of my old mustangs I had a fiberglass hood and it did this pretty bad at high speeds but I never had any issues. Unless the locking mechanism fails, the hood is not going to rip in half and fly off.

Mine does it as well. It's part of the professional grade package.

You mean "professional vibration package"? :crackup:

It's all aluminum so it has give. I will not even put my weight down on the hood when I wash the truck.

aluminum is lighter and thinner ... ... anything to make the truck lighter each year. god awful driveablity and front air dams that site a foot off the ground. You demand great gas millage.....here is your receipt.

 

GM doesn't care.. at the end of the day that just want to do whatever is needed to claim better MPG than Ford... whatever it takes.

While aluminum is about 3 times lighter than steel per equal volume, this does not mean they could not make the aluminum hood with enough stiffeners to prevent flexing and shaking of the hood.

Exactly. The problem is not the material that the hood is made out of. The problem is that gm doesn't give a shit.

I have only had my truck for a week. This was the first issue I noticed with the truck, I guess since it was really windy the day I picked it up. My 08 Tahoe's hood was steel and didnt flex in the slightest bit. I wonder if putting something on the backside of the hood like dynamat or something similar would help

      I did the new thermostat after doing a 'flip' for a year. Runs as cool one way as the other in the summer but in the winter there is a bit of a floor. Yellow with the new 70 C thermostat. My data over the life of the unit to date. Still need more cooler. Anyway that floor helped both winter fuel economy and shift quality in the winter. I found it a good balance.

      Evan Williams Bottled in Bond   So pouring the last of a bottle of Evan Williams Black label last night I set off the the state store for a refill only to be denied the by an empty shelf. Rats.    What the did have was a bottle of Evan Williams Bottled in Bond. 100 proof. Hum, a few bucks more but a known distiller. Lets have a swing at it. ( I have before )    Cracked it open and pour a serving over ice. Hum.... more heat, yes. More alcohol naturally. But the barreling not the proof brings the taste and this one came up short.    Oh is was familiar but the heat ran the barrel over like a Peterbilt runs over a squirrel. Could use a heavier toasting of the oak me thinks or perhaps a longer barreling. Who knows. But what I can say is ice or a water back isn't the answer. What kills one kills them both. Sad. It is a pleasant drink....if you have little to compare it to.

      Bridgestone vs Goodyear tires?

      By Grumpy Bear · Posted

      I've had exactly one set of Bridgestone. Lasted five year and 125,000 miles and had I known better 15oK would have been a cake walk. I would have bought a like set had they not tripled in price since the first set. I removed them at said mileage with 5/32" remaining in dead even wear all four. They were fuel efficient, quite, comfortable and predictable.    Early on I got a very good alignment checked at least once a year, sometimes twice; kept the tires properly inflated, balanced and rotated. And I've found that many a tire issue can be avoided with great maintenance practices. Lot's of tire dealers will do rotation and balance (simple) for free for as long as you own the tire they sold you so no excuse not to.    Bead prep, alloy integrity and stem health have a huge impact on inflation stability. There are more mountings done poorly that perfectly. Finding a good tire guy is gold and as important as finding a tire you like.    That 3X price increase now two sets of "other tires' later is starting look like a bargain.      Bad maintenance kills more tires than bad tires.
