Toyota Repair: A/C and aux. drive shaft problem, drive shaft, steel inserts

Question
On my 1997 Previa the front part of the Aux. drive shaft make a rattling noise and wobbles when spinning. Is there a bearing that could be worn? There is also a chirping sound when the A/C is turned on but the belt is fine.  The fan doesn't blow all the  time but when I took the fan out and tested it, everything was fine. Can the Aux. drive shaft cause the lack of performance of the cooling system? I appreciate your help.

Answer
Ther's not really a bearing it's arubber joint with steel inserts ,t he rubber cracks sfter time and causes this condition, there are repair kits for some model previas but for some the entire shaft must be replaced, either way it's an expensive repair because of the labor involved replacing both front and rear joints. Not sure if it could cause the a/c problem, I really don't think so, in any case I would do the driveshaft first and then see if the noise is still there, the shaft has no effect on the cooling system otherwise.
