is the 205 x3 known for the forward part of the driveshaft breaking w/o a hit?

What is your question?

I hit something in the rd lost the shaft differential , transfer case . my ins will not pay said car is known for that! it is bs. this is with safeco/liberty mutual they will not total it or pay to fix. you can't break a driveshaft without hitting something it will cost a little o/ 4k to fix how can i prove my car does not have drive shaft problems ?
