High pressure sintering of powdered metals like that is also basically the only way to handle stuff like pure tungsten (given the temperature it melts at) - the cubes of tungsten I had made last year were sintered and machined.

I had a fun experience with my '88 BMW 635CSi. I noticed that when I was turning at low speed, I would hear a CLUNK from the driver's side front wheel. I jacked it up, and saw that the Lower Control Arm bushing looked like a stepped on jelly do-nut. Now, I do a lot of my own work on my cars, but I'm not really set up for suspension stuff. Especially on this car, which requires that you have proper load on the suspension when torquing the LCA nut. (I mean, I could put it on jack stands, then put a jack under the spring perch and compress it until it appears correct, then try to torque it to spec while praying the jack doesn't slip and maim/kill me, but I'm not that brave anymore) Anyway, so I took it to a local reputable shop and told them what I suspected the problem was. They called me a few hours later to tell me that the issue wasn't the LCA, but that I needed both of my thrust arms replaced, which would cost double what the LCA would cost. Now, this was going to take ALL of my money now, but I figured that it was best to spend it so my car would be safe to drive, right? Well, I go to pick up the car. Pay them, go to start it and the whole thing goes tits up. A myriad of things were wrong, but I later found out that it was because the battery had gotten too low*, and that makes BMWs of this era very, very angry. The mechanics all hosed off for the day, and I sat around in the parking lot trying to get my car to run. A friend finally came by and we charged the battery a bit and it made it to my garage. HOWEVER, on the way there, I noticed that the CLUNK was still present. I have contacted the shop and they insist that the LCA was fine, and want me to bring it back and see if they can discover what the clunk is. For reference, this is a picture of the perfectly fine LCA bushing:  So, you tell me, was I the mechanic failure, are they wrong, or could it be a combination of the two. *how the hell it got so low is a mystery, but they acted like it had arrived that way. It hadn't. EDIT: Balls, I meant LCA Ball Joint. (It's usually cheaper to have them replace the entire LCA in one go, and that is what I asked them to do. But they didn't) Jackie the Mick fucked around with this message at 19:30 on May 2, 2016 |

What I told the shop was "It's making a clunking sound when turning at low speeds and I suspect the Front Left LCA needs replaced.") Regardless, am I wrong in my diagnosis? I just don't have tons of experience with suspension components, but it seemed pretty straight forward.

You would have to jack it up and pull on a pry bar between the lca and knuckle to check.

as a conclusion to the weird vibration that I thought was wheel weights, you guys were right. nothing to do with that. it was this. couldn't see it initially because it was at the top. checked it again after parking somewhere else and saw this staring back at me. yikes. oh well, it needed new tires anyways.

Can we do horrible home owner ignoring bad sounds causing appliance failures in here? Dryer has squealed since I bought the house 5+ years ago, never really bothered me enough to look into it. Last week I started a load and left, came back later and everything was still damp. Wouldn't restart and turning it by hand was clunky and difficult. Finally tore it apart... There is supposed to be a ball sticking off the back of the drum here  Found the ball, not exactly where it is supposed to be  Not very round anymore either  Well this explains the metal on metal grinding sound

Could be from a bent wheel, an idiot putting a wheel on the machine a little tilty/not tight enough and the machine seeing a massive side to side imbalance, or a flaky machine and a no-fucks-given lazy worker chasing the remaining imbalance around the wheel, dutifully putting on another weight where it says every time instead of thinking and realizing maybe the machine's gone wonky. e: IIRC a busted belt can cause funky issues and freak the machine out so it keeps telling you to add weights too. Not sure it'd result in a pattern like that.

The heat strip is generic and also cheap (for appliance parts). It is carefully engineered to shred your heat strip and the fragile ceramic spacers that hold it, so make sure to check it and related wiring before reassembly. Have fun!

Don't forget to buy the felt around the front of the dryer door the drum rides on. If the rear bearing is that bad, the front felt is probably worn pretty badly too. If it doesn't seal properly you won't get enough airflow over the heating element and it will trip the thermal overload.

What happens when you don't properly secure a 40,000 lb steel coil on a flatbed trailer?  Apparently it shifted on an offramp and pulled the trailer over with it.

Balljoint? it's probably a failed balljoint.   All the lugnuts were sitting in the driveway and the wheel in the passenger seat. maybe the BJ failed, took the wheel off to make it easier to drag it?

That's standard procedure in lots of drag cars. Hell, the nitrous outlaw cars often try to get the turbo cars to heat soak by making them stage first and then sit on the rev/2-step limiter for ten seconds. sharkytm fucked around with this message at 14:40 on May 13, 2016 |
