2013 gs350 fsport awd.
replaced serpentine belt recently but sounded like bearing issue after. Thought maybe it was my idler pulley so I replaced that one easily. Still some noise so I’m thinking it’s my belt tensioner pulley. Should I just replace the bearing wheel part whole the whole tensioner pulley that has the moving arm? I’m not experienced at all in doing these things. Just trying to get thoughts.
If you don't have a car stethoscope, you can use a long screwdriver and hold the handle up to your ear and touch the tip to the center part of the pulley to see if it sounds like any bearing grinding sounds. Obviously don't touch the tip to any moving part.
As far as removal, it looks like it's 4 bolts for the AWD model (5 for RWD), but it also looks like the AC compressor might be in the way? I'd probably wait for others to comment who may have done it.
