Last winter i rebuilt my engine, fitted new driveshafts, wishbones, shocks, clutch and so on.
Since then i had 3 broken Gearboxes in about 4kkm.
Every time bearing issues from the input shaft or the differential.
After two broken gearbox each lasted maybe 1kkm (input shaft play) i swapped the crank from my old engine in.
Then put the crank on some bearings and measured 3/100mm radial "dimensional deviation" when you turn it.
Now the gearbox lasted nearly 2kkm. then this happened.

The crown wheel came loose on the differential.
One cv boot from the short driveshaft was torn, so replaced that one, but there was no damage inside of it and i cannot explain how the boot twisted itself?
First Gearbox was a VTS Box, second was a 1.4XSI, third was a 1.4 Furio.
Today i've fitted my 4th gearbox and i noticed that the driveshaft has play in the gearbox. (short one, drivers side for me and passenger side for you, beacause mine is lhd).
The driveshaft shouldnt't have any play whatsoever? am i right?
so had 2 other boxes lying around tried the driveshaft in every one of them and everytime the same play when its in?
I'm not sure about my english here but maybe i bought some "reject goods" as new driveshafts.
The first two boxes where damaged beacause of the bad crankshaft, but maybe they werent just not long enought in the car to have the same problem as gearbox number 3?
Can the driveshaft with play be responsible for my 3th broken gearbox?
The driveshafts where from the brand "cevam" cost me about 130 euros for both.
