Modern f-150s have that same problem. A vacuum leak results in the hubs locking/unlocking at speed. That however, looks like it was driven another 50k after eating the u-joint.

Vacuum auto hubs? What the christ? I've seen vacuum locking diffs but hubs, seriously? Is there like, a seal wear spec where the vacuum can escape but not at a greater rate than the pump can supply? What happens if you...actually go offroad or something?

In my dodge, the failure mode was unlocked, which is bad because the entire assembly on the dodge is mounted on the back of the front axle, and is prone to getting removed by deep mud.

I don't see how that's bad because the failure mode was unlocked? The two seem to be unrelated issues.

I'm assuming that when you're in deep mud you want your front diff to stay connected to your wheels?

If the mud has already removed your front axles from the car I don't think it matters whether the failure mode is locked or unlocked, or maybe I'm misunderstanding what is failing here.

He's referring to the vacuum actuator setup being mounted in harm's way on the front axle. Deep mud or other obstacles presumably tear it off and strand you when you're suddenly balls-deep in two wheel drive.

That's one failure mode for Ford. The hubs on my '01 F250 are open and won't auto lock due to either a vacuum leak somewhere in the engine bay that I can't be assed to track down or a weak vacuum pump. There is still enough vacuum to work the A/C blend and vent controls, and the brake boost is hydraulic so I'm cool.

They get filled up with water and rust in whatever position they were last in. After those are replaced you can figure out what ELSE is wrong with the system. It's a truly horrible setup, but....hey, it worked for all 36,000 miles of the warranty so good enough, amirite?

So glad Jeep strayed away from locking hubs and vacuum axle disconnects with the TJ and haven't gone back. A/C and heat blow dicks to make up for it though.

At least with the dodge isnt too hard to keep the front engaged without a vacuum, I simply pushed the fork into the engaged mode and filled the damned vacuum actuator with hotglue. Didnt hurt the always abysmal mpg one bit if the hubs were unlocked.

at least on 94 and later balljoint dana 60 front dodges (all 2500s and up basically)* you can put a cable shifter on instead of the stupid vacuum setup. And if you want your fuel economy back, grab the knuckles-out including stub shafts off a balljoint f350 frontend, it bolts right onto the dodge housing. F250 ttb outers work too but the kingpin axis of inclination is different so you will end up with hella tite camberzzzzz thus this is only recommended for offroad-only vehicles. * 93 and down are kingpin with no vac disconnect and I don't know anything about parts swappability on 1500s and down with vac disconnect 44 front axles, sorry.

So I just put a big-rear end post on Ford's facebook wall, but I won't subject you all to that. I just changed the filler neck on my 2000 Mustang because the clowns that designed the part wrapped part of it in plastic corrugated tubing so it could collect dirt and rust the filler neck. Tadaa.

MV Agusta F4. Guy takes it to dealer because its ticking, they open the engine, found nothing wrong, sent it back to him. 500mi later it did that. (I don't think they used enough RTV on the case halves )

Haha, I had the same feeling about my old Triumph 675. I said something on the forums about being worried about it blowing up and everyone told me I was crazy. Month or two later at a trackday it seized at ~100mph. I come out of a corner onto a straight trying to catch a Yammy 1 liter with an instructor watching us from behind... some brake and drop a gear to prepare to drive out of an upcoming corner and it just locks. Instructor came to talk to me after, good times were had.

Do horrible electrical failures count? Prepped my Wrangler to be painted at my place. Degreased the exterior, under the hood, sanded everything, etc. Jumped in it to head to where I'm painting it and it just dies at the end of my road. Check fuel, check spark, (it's there but weak and yellow). Stumped, I checked the distributor, battery voltage, started wondering if I flooded the ECU with water. I decided to grab the coil and bench test it. Yep. I think it's done! EDIT: Forgot to add a pic of the finished project. It's been 20 years since I've held a spray gun. It's got a couple of minor issues, but it's a fantastic reminder of why I hate body work and painting cars. Team140 fucked around with this message at 02:13 on Dec 16, 2013 |

Lazy/inexperienced technician. Not to mention if you have the motor out on a bench and you put it together, it isn't hard to just wipe down the excess before you stick it back in the bike. Also they potentially weren't able to separate the cases properly and resorted to prying at the flanges.

A tech at my old dealer did that to a timing cover on a K20 and ended up with a pickup screen full of RTV and a burned up motor. I don't think people understand how little sealant is needed and that, even if you use a tiny bead, most is pushed out the sides and ends up doing gently caress all.

Shouldn't a memorial where a guy died in a car crash not have a lot of cars in it? That's like going to a memorial of somebody who was killed by a circus tent collapse dressed as a clown.

On the other hand if the dude loved cars as much as everyone says he did, he'd probably think it's cool. I don't understand why anyone would sit on the limiter for 15 minutes though. Was it just to make parts of his car glow? Does he know lightbulbs and LEDs are much safer technologies for accomplishing that?

How the hell did he get to fifteen minutes banging off the limiter without someone coming over and shoving his teeth down his neck?

Anyone who's into cars should know that a car banging off the limiter isn't awesome, it's the sound of a machine being beaten by its owner, and that you need to step in and punch him in the mouth before he breaks it.

Everything about that sequence of pictures is as it should be. A person who does not deserve nice things, takes a thing, ruins it, then later destroys it with his own stupidity. It's a self serving problem and the world is slightly better than it was before that fire started.

It's pretty amazing that it didn't melt a piston from the lean condition before the exhaust manifold caught everything on fire. Ford should use that as a testament to how durable the zetec engine is.
