Almost certainly do, Astra, cavy and calibra all load suspension weight through a Mcpherson strut on the top of the suspension upright. this leaves the bottom joint mainly doing location work only.
The maxi balljoint is larger and on the original car took the suspension load.
The astra joint may last or it may not.
Many years ago ( back in the 80's / 90's ) a fair number of 747's lost their engines (literally). Mainly Pratt & Whitney ones not RR ones. The conclusion was that the bolts holding the engines to the airframe were perfectly up to the task of taking the thrust during flight. But the reverse thrust during landing caused stress on the bolts eventually leading to them shearing and the engine falling off.
