General wheel collapse

[woody 650]

hi my sons got a money pit otherwise known as a ducato 14 lwb 1999.whist driving it tonight there was a loud clonk and the front near side appeared to have dropped down onto the front wheel.ON reversing the van it leveled itself back up and no evidence of problems could be seen.He drove on further and the same thing happened,this time seems permanent......any ideas?The front strut this side was repalced approx 4 months ago,could this have anything to do with it ?cheers

hi.on looking in the light the ball joint has dropped out and pulled the drive shaft out,is this just unlucky or could it be something to do with the strut having been done weeks earlier?
