How can Ford have released a motor that had so many problems that step 1 of the recalls (over 40 individual items) was "remove cab from vehicle"? (I'm talking about the 02-ish 6.0L diesels). How could they have accidentally put a cruise control switch on the master cylinder that allows brake fluid to pass though it resulting in trucks catching on fire after they have been switched off? (96 through mid 2000s light trucks and most cars) How could they have put the wrong oil (maybe, there never was a real answer) in thousands of Probes back in the mid 90s causing them to need to have heads replaced at their 3rd or 4th oil change interval? How could they produce millions of heads for the modular motors over the ourse of several YEARS with insufficient spark plug thread depth?

How did ANY of these issues get past "a company who probably did extensive r&d"? I don't have that answer, but they all did. None of these are even up for argument, as they are all very well known issues and/or published recalls.

None of this is even unique to Ford. It happens to all major manufactures who we have to presume "probably did extensive r&d" as well.

Dude, you obviously have something against Ford and it's affecting your opinion on the obvious user abuse of the Raptor. Can you please just let it go?

I Want To Believe.
Due to the fact people refuse to stop bumping the subject of bumpstops, I'd point out that from what Ford's saying, they did put a deliberate failure point into the bumpstop:

quote:

...the first thing when you do exceed the vehicle's travel capability [is that] you have a certain safety zone where you will hit the bump stop and nothing will happen. If you hit that same obstacle at an even faster speed, then you will yield the jounce bumper cup – that's the little piece of steel that holds the jounce bumper. If you hit that same obstacle at an even greater speed, then the next thing to go is the frame.

Combine that with their advice about practicing runs at gradually increased pace, and it's hard to come down that hard on Ford. If it were me (in the manufacturer's position), I'd also go do a run on that track following the stated advice so I could come back and say "Bottoming out occurred at Xmph, initial failsafe triggered at Ymph, frame failure occurred at Zmph". They need to show that the point of frame failure is substantially beyond where they decreed the "failsafe" point to be if they want to get people on their side.

They should also answer the questions about the access hole in the frame, preferably with the difference in load required for the same deformation in a plain-walled section.

Apparently the speeds involved were relatively low (~30-40 MPH). I'm posting this in the mechanical failures thread because a) his airbag failed to deploy and, b) Toyota (that used to be a Corolla) safety????

It seems your friend is the one that's lucky no one was in the backseat. He must've riding the poo poo out of her rear end to do that much damage. And I'm no expert but unless that lady was at a complete stop there's no way that's a 30mph accident.

Apparently he was taking a swig out of his coffee while cresting a slight hill on a freeway on-ramp. CalTrans had just installed a brand new metering light (this was the first day it was up and running) and the car in front of him had just got the green when he cleared the crest.

To be fair, the Silverado overran the rear of the Corolla, so all of the energy was absorbed by the trunk lid and contents. I don't really see how that could be prevented. I've read a bit about overrun protection in train design, and even if you wanted to spend the weight I don't see a lot of structure in the area that the vehicle was hit. But yeah, your friend's right to own a large vehicle is now rescinded.

I wonder if the shocks were blown on that Corolla beforehand and the lower ride height put the Silverado over the bumper in the impact.

by the way the airbag not deploying is a system failure and the damage done isnt an inherent safety issue with toyotas, its physics and crumple zones doing their work. big pickups and suvs have a lot of momentum at 30-40 mph and ride much higher than a 3rd or 4th gen corolla so its no surprise that the back of that car got reamed.

while impressive, there isnt any mechanical failure there, just an accident.

This happened in Central Cali where the mindset of "bigger is better" is alive and well. I showed this picture to a couple of my friends and their "hurp derp this is why big 'merican trucks are better" response was typical redneck all the way. It's funny because a stock Silverado around here is a small vehicle. If that car had been rear ended by one of the bro-truck driveway queens that frequent the area that lady would likely be dead.

Sounds just like the stereotypical American driver, driving a big vehicle and paying more attention to their cup of coffee than where they are going.

Anyway cars (especially mid 90s Toyotas) just aren't designed with rear end collisions in mind - that just isn't where the testing is done. The height mismatch obviously doesn't help either.

10% more speed and a kid in that back seat and your 'bro' would be facing some serious charges. "I didn't know they changed something on the road" isn't an excuse for crashing into someone else - only an admission of being an ignorant manchild.

But in other news: Supposing that was a 30mph crash, is it just Toyotas or are all modern cars that crumply? When my '90 Legacy Wagon got rear-ended at like 40-45ish a few years ago by a Town&Country, despite being totalled the car still drove 30 minutes home under it's own power with the only major problem being the lack of a rear hatch window.

Silly goose, you're here forever.

The problem was a combination of the fact that the Chevy was less crumply than most cars and that it was high enough that the entire truck just rode right over the Toyota's bumper, which is where most of the rear impact protection is. A trunk lid can only absorb so much force.

A Town & Country doesn't have quite the same ride height as a Silverado. If the friend had been driving one of those, the hypothetical kid in the backseat would probably have survived, because the bumpers would have actually been relevant.

The impact structure of the Corolla is almost entirely intact, the reason it looks so bad is the truck rode up and used the trunk and firewall as an impact zone. That's also why the truck didn't deploy airbags and looks like it was in a 5mph.

Because every person that's died in an accident has resulted in the person at fault being charged with a crime. :wtf:

I guess where you live there's only at-faults. But I digress...

After studying the pics a little more it looks like you guys are right in the pickup riding on top of the frame. Also, it looks like an older Corolla so it likely wouldn't hold up as well as a newer model would have.

I don't know about that - due to the awkward way it hit it may have been quite a low speed.

Also Cuntpunch may well be overestimating the speed his/her Legacy was hit at. I've seen a late 90s Legacy rear ended by another mid 90s Legacy at what the Police said was 70kmh (a bit less than 45mph) and it wasn't pretty. There was far more rear end damage to the hit car than there was front end damage to the other one.

Nobody's disputing that he's at fault, it's pretty clear given the circumstances and the fact that he rear ended her. In CA that's pretty much all the evidence insurance needs to right you up for an at-fault accident.

This is from a fossil plant, which means I can post it here without getting fired. If you work in the industry, you've probably seen this before; it's the eight million dollar roll of paper towels picture that FME coordinators everywhere love.

That's a 500 MW gas turbine from a plant in Texas. Operators entered the turbine housing during an outage to clean the inlet guide vanes. Upon their exit, they left their paper towels inside the inlet mouth. This resulted in a partially blocked inlet, and thus a low pressure zone inside the turbine. 23 hours later, they had what you see above.

I think there is a huge disconnect between what is a serious crash and what people think is serious crash. I mean, when someone says "it was only 30-40mph", to me they're admitting they have no understanding of the massive forces involved. Most crash testing is done at that speed range.

That's my understanding of the event. I live in steam turbine land, but any turbine in which the blades pass through a pressure differential is going to shake itself apart eventually. The truly :psyboom: part for me is that they ran for 23 hours like that. I know things are different at gas burners, but I'd like to think we would have been tripped on high vibes an awful long time before there were blades lodged in a wall.

Yeah, that too.

We had a "re-engagement" on the importance of foreign material exclusion logging two outages ago, when a plastic cap for excluding foreign material got lodged inside a thrust bearing and delayed start-up by close to two weeks. The irony of the FME cap becoming an FME hazard was lost on no-one.

If you work out the cost of an outage extension, that FME cap actually cost us more than the Texan paper towels, but the pictures aren't nearly as interesting. Also, posting them could get me fired.
