Which Idler Pulley?

Got the annoying squeal, and my car just went over 47k so this weekend is routine maintenance weekend. Gonna go with Synchromax in the 3650, new fuel filter, gatorback belt, and new idler pulley. I found one that has a very slight wobble to it, so Im hoping thats the one I need to change.

2

Drive belt
3

Coolant pump pulley

Power steering pump pulley
5

Crankshaft vibration damper
6

A/C clutch pulley
7
6B209
Drive belt tensioner
8
19A216
Belt idler pulley
9
19A216
Belt idler pulley

The one in question is #9. Is this the one that tends to go bad and most of you change out? I know that one and the tensioner pulley, #7 are identical, both smooth right? What about #8, the grooved idler? Is that one prone to bearing failure? If so I may just change it while the belt is off. And can someone verify the torque value for the idler? My Haynes says 15-22 ft/lbs, but its not always acccurate. It doesnt even show the #8 pulley in the belt routing diagram.

and this is the replacement I was going to buy for $10.
