Update: Had new drive shafts fabricated and fitted. Have done a few hours of freeway driving on them now. The truck is no longer shaking violently and is actually becoming nice to drive. No longer losing the alternator bolt. Have checked it recently it's still on and tight.

I don't have high hopes in improving the fuel economy of the truck but I do hope that I can find lower cost fuel sources to augment the diesel. I'm hoping that methanol/water can help. Diesel is currently $3.50-$3.80 a gallon in San Jose CA.

so it looks like modern diesel engines get some 45% efficiency. https://en.wikipedia.org/wiki/Engine_efficiency Diesel engines[edit]Engines using the Diesel cycle are usually more efficient, although the Diesel cycle itself is less efficient at equal compression ratios. Since diesel engines...

I'm currently getting over 8 Mpg out of my truck but it's unloaded. Rumor has it you can get 10 out of the truck with tuning, tires, high speed gears. From what I am reading methanol/water injection could help some maybe 2 mpg and there might be a newer more efficient turbo available. It would...

I will check this on my vehicle ASAP

When I replaced the missing bolt in my alternator I just pushed the tensioner with my hand and tightened it down. The belts are not max tight but they seem to work great so I'm not messing with it. It's miles away from a modern car with a spring tensioner.

Every bolt I have put a wrench on has been very loose or easy to remove. I'm not sure the torque specs are very high or things have just loosened by vibration.

Another data point. I lost my alternator bolt twice and my water pump was replaced before I got the truck (still unpainted). I checked my drive shafts for play and was able to shake them. I took them in for rebuild. The splines were trash, the main tube was bent and the u-joints were too work to...

Tell me more about this wheel balancing using airsoft bbs

More on vibration analysis. There is an iPhone / Android app for $400 that does full driveline analysis. Sent from my SAMSUNG-SM-G930A using Tapatalk

So while on youtube I got a targeted advertisement for a tool that uses a laser to analyze vibration in motors and drivelines. http://www.fixturlaser.com/Shaft-Alignment/Fixturlaser-SMC/ I have no idea how expensive it is but it sounds awesome!

That MHC is killer. I think I got to get one now.

Well when Aesomeness get around to more research on this please do share it. I'm not looking forward to getting my drive shafts rebalanced or rebuilt every 15k miles. I did notice that my truck has 16k on the odo and it's starting to play up like one of the previous posters.

Whoops. I meant bolted on. Sent from my SAMSUNG-SM-G930A using Tapatalk

Is that a committed on part? Sent from my SAMSUNG-SM-G930A using Tapatalk

Is it possible to get custom shafts with that joint? Sent from my SAMSUNG-SM-G930A using Tapatalk

A few points: 1. If someone put together an "emergency" kit that included: Alt L bracket, Alt Bolts, Alt belt, Water Pump, Water pump belt, Water pump seals, Easy out, drill bit, Loctite. I would certainly buy one. Anything else that would be required to make sure you can sort out this...
