i have forgotten basic innova.
is that an idler pulley, moving up and down or side to side? (this is normal for idlers.)

good pulleys won't wobble, regardless of belt condition.
it might seem to, but a good inspection will prove the otherwise.

there are many failures that can weaken the AC. belt slip is one of them. belt slip has several causes.
do not assume.
one must investigate.
Agreed. This is why belts should be checked/replaced regularly... And while the mechanic is at it... All pulleys must be checked.

I experienced seeing my tensioner pulley wobble, only to find out that the main/crank pulley was the one broken.

So, yes investigate, investigate, investigate
