I thought it may have been that Febi wasn’t that good and was gonna order genuine BMW but I did some more digging on the internet and found that if the universal joint on the driveshaft is stiff or notchy, it’ll cause the CSB to fail. I never paid much attention to the condition of the universal joint when I had the driveshaft out but on the final time I found that it was indeed very stiff. So I ordered a driveshaft from Import master replacement driveshaft listing for BMW driveshaft, Mercedes Driveshaft, Volvo Driveshaft and all is good now. A much beefier and serviceable universal joint vs the oem shaft. It comes with everything except the guibo and cover for the cv joint. I highly recommend anyone in need of a driveshaft to order from them. From phone call to receiving the shaft, it took 4 days for them to build, balance and ship it.
