So far, my old think-box seems to work okay.
My '85 Toy is a solid front axle, the last year Toyota did that before going to the double wishbone. Mine is stronger for off-road bumping and thumping. I griped to a salesman, who responded: "Art, you're only 20% of the market. We have to sell to those folks who don't go off-road, who want the better ride and handling."
They cater to the majority of the market.
So, similarly, in today's world, if you want a full-size "work truck", you either get a 1/2-ton with a towing package or you move on up to a 3/4-ton. And if you don't want the bells and whistles which happify most people, you have to special order.
Rebuilding is cheaper, but from a reliability standpoint it's better to get it all done at once instead of only fixing something after it breaks and doing that event by event. Do bushings, brakes, shocks, U-joints, hoses, belts, radiator all at once. It's a bigger lump of cash, but in the long run it's cheaper because of less down time.
