Not every truck advancement in the last decade has been good. Torque tube suspension comes to mind. What where people thinking? That it wouldn't twist the frame rails in an "equal yet opposite reaction". I do agree that 60's and 70's technology was severely lacking in comfort and reliability, but the newer stuff isn't always an advancement. Sometimes its just window dressing to make a selling point. That's why I only look for vehicles made in the 80's and early 90's. Advanced enough to be comfortable and convenient, yet enough old school to be reliable and easy to work on. Nowadays you need a computer science major to work on the damn thing with all the high tech gadgetry they cram into vehicles these days. Back in the day, a vacuum controlled engine was just as good as some of the newer electronic controlled engines are today. Certainly easier to fix too.
End of rant.
Torque Tube? I had to look that up on google to even know what that was.
As far I know there are no modern vehicles using this. According to Wikipedia
"Examples of the torque tube were the American cars of the Ford brand up through 1948"
So apparently it hasn't been used since 1948. Not a good example of modern technology being bad.
For the most part modern 4x4 suspensions now consist of coils springs and A-Arms for the independents, and for solid axles either coil springs with a 3 or 4 link, or the venerable leaf spring. All of which work better than the rock hard solid axles of old, with zero computers.
So what modern suspension technology do you dislike?
I currently do all of my own work on vehicles, and have helped some friends fix their vehicle. No science degree needed. Failures are less common than they used to be, and when there is a failure, the computer tells me what it is so that I can effect a repair easily. Code readers are cheap and easy to use, and give you more information about problems rather than less.
The last thing I want is to go back to the days of carburetors. They suck gas, clog frequently (especially if it's not your daily driver), require re-jetting to compensate for elevation changes (or fuel changes for that matter).
I've rebuilt way too many carbs due to fuel turning to varnish than I ever want to again.
As far as vacuum operated gadgets, again, the last thing I want to do is go back to hunting for vaccuum leaks. Or rebuilding points.
The technology you hate has enabled vehicles to travel several times farther without a breakdown. And when there is a breakdown there is usually a limp home mode.
I was just helping a friend fix her Toyota Avalon. 228k miles. We swapped out an oil control solenoid, and cleaned a filter. 2 bolts, 20 minutes, and she was back on the road. Still running reliably even in this -10 degree weather. Last carbureted car I had required starting fluid, 2 people, and a stroke of luck to start in weather like this. No thanks.
The only benefit I can think of for an old all mechanical vehicle like that is in a nuclear war scenario the EMP blast would disable modern electronics.
