Hello I will help you with your question,
Where did you place the throwout bearing when you installed the transmission?
The bearing is placed on the input shaft then the fingers of the piviot shaft are threaded into the bearing as you install the transmission. Once the transmission is bolted solidly then you install the lever to the shaft and snap the bearing into place in the snapring.
You have a new pressure plate and bearing?
Install the slave cylinder and carefully bounce the arm with the clutch pedal. If you didn't use the Hyundai parts this may not fit as well and will take a little more pressure to snap in but don't stomp on the pedal as you can bend the throwout lever, just bounce and feel for the bearing to snap in.
