Does it make sense to replace just the bearing inside the pulley? If someone have done that, any part number? Thanks!
Only if you have less than a few years on the assembly. As others have indicated, it's usually the tensioner spring that gives up first on the OEM part, so if you have an original tensioner assembly, you're probably money ahead by replacing the whole thing.Does it make sense to replace just the bearing inside the pulley?

Thank you for the reply. Spinning all the pulleys did not point to the culprit. I will replace the belt, and if the problem is still there, will replace the whole thing - the tensioner. The bearing was only $4 shipped.remove the belt and then individually spin all of the pulleys to see what is squeaking. Or, your tensioner isn't tight enough to keep the belt from slipping.
Replacing tensioner bearing did not help. Replaced the tensioner and the noise is gone. The tensioner I have replaced was not an original one either. It's my impression that an average LT1 goes through several belt tensioners during its lifespan. 95,000 miles and at least the third belt tensioner in my case.Ever track down that noise? I have one and am ready to replace the tensioner too. May seem weird, but I took a trick from an old mechanic to pin point noises...used an old peice of tubing held to my ear to ID the offending pully. Point one end of the tubing to your ear, the other at the suspects.
