is there a easy way to tell if a drive line is straight? i dont have the money for a fancy new one and i dont wanna screw my self by buying one thats already bent.
Take a long straight edge(the length of the tube section of your drive line), or a piece of string and some duct tape. Lay the straight edge or tape the string to one end and pull it tight and hold it to the other end, along the drive line on four opposing sides. If you can see a gap between the straight edge or string line anywhere along the drive line, then it is bent. This wont guarantee the driveline is good, only that it isn't bent, you would still need to have it balance.
