There kind of is. The Chevrolet Express/GMC Savannah vans have remained largely the same since the late 1990s. The design of the headlights and grill have changed a few times, and there are several different versions of the engines, but stuff like brake systems, heater controls and fans, seats, instrument panel, etc. are more or less the same. I don't think GM makes passenger versions anymore, but the cargo vans are still super common in my area (southern Ontario).

Have they actually improved its weaknesses, though, besides upgrading the engine from time to time? For example, today I replaced a front wheel hub-bearing on a FWD car. These are designed with a cast steering knuckle that the axle goes through. The bearing assembly is mounted on the front of the bore, the axle goes through the bore into the hub-bearing from the back, and there's a little seal on the back of the bore that the axle rides on.

The weakness is that water inevitably gets into the bore around the back seal (since the axle moves around a bit) and the only way out is through the bearing out the front. It rusts out. Nobody has improved this design for the past 50 years, as far as I am aware. Perhaps a weep hole? Perhaps they need to be completely filled with grease?
