Basspro has switched reels out for me before no questions asked. I have an older Citica that was making a louder buzzing sound on long casts. On that reel the small round plastic things that control the magnets were worn out and were rubbing when you made a hard cast. I switched them out and the noise went away. Check them and see if they are dark or burnt on the ends. The loud clicking noise that you are describing may be a little more serious though.
