Front wheel drive and the MacPherson Strut front suspension are the culprits. No (or a very small) upper control arm makes for a very light, efficient, and compact front suspension. But it's not nearly as robust as twin A arm front suspensions because the lower control arm must do it all.

While I would agree with the above statement that current front suspensions are not much if any more fragile than those from 1995, the MacPherson strut front suspension has been wide spread since before that time. If you go back into the 60s and 70s before MacPherson became wide spread, you don't see the type of suspension separation that you see now. At least not nearly as often.

And you don't see suspension separation on larger rear wheel drive vehicles like full sized trucks and vans even today. Those vehicles aren't suitable for MacPherson Strut front suspensions due to the heavier loads that the front suspensions must deal with. On those vehicles, the front suspensions are basically as robust and resistant to separation as their counterparts were 40 or 50 years ago.

Front wheel bearings are another casualty of lighter, cheaper, more efficient....and more fragile modern front suspension designs. The ball bearings used in most MacPherson Strut front suspensions won't tolerate much in the way of side impact. Curb one once and it will be noisy thereafter. That wasn't true of the tapered roller bearings that we have in our muscle cars. The tapered roller can withstand much more side impact with little or no problem. That was the reason Mopar used tapered rollers in our rear axle bearings rather than the ball bearings used in the 'Green' bearings that many people like to use so that they don't have to adjust preload. Ball bearings on the rear of our cars do survive better than they could in other applications because they are better supported by the axle shaft.
