Yeah, but if you replace the diff, gearbox, and motor, how much of the cab is really left (mechanically speaking)? Replacing the engine is, from an engine-maker's perspective, the same as buying a new car.
Yeah, but from the cab owners perspective, $600 for a reconditioned diff or $1200 for a reco motor is a lot less hassle/expense than $40k for a new car, then getting all the cab-specific fitout done to it...
(Yeah, that's what the base model cars used for cabs cost here. Google Holden Commodore or Ford Falcon prices. New car prices in Australia seem stupidly high to people used to American car prices...)
Why the downvotes? I'm serious. If cars start lasting 600k+ miles and are shared by multiple drivers and families, car companies will ‘need’ to recoup their losses. Expect prices of car components (the stuff that wears out) to skyrocket, and patent litigation to get rid of the after-market/3rd-party compatible components.
I don't think you even have to imagine any malice or profit-protection on the part of the manufacturer to see that.
The simple fact that current cheaper parts are going to be replaced with higher-quality parts is going to cause a corresponding rise in maintenance and replacement costs.
Maybe. Keep n mind these's a lot of parts of a differential (or motor) that _dont_ need replacing when reconditioning. In a diff, there's maybe 9 bearings, the pinion and crownwheel, and maybe the 4 spur gears. If you start with an undamaged but worn out diff, replacing those parts effectively gives you a brand new diff. The bearings are standard industrial parts worth maybe $40 or $50 ( at retail prices) and the auto manufacturers can't affect the cost/margin on them. The crownwheels, pinions, and spur gears are already all available from aftermarket manufacturers for any model likely to be used as a cab (at least here in Australia).
