For me the squeak was for two different reasons at different times.

On my first visit the TSB called for replacement of the assembly. It went away for sometime. Months later it came back. They re-torqued everything a couple of different times - no improvement.

Ultimately the Service Manager gave me the silicon lube I applied it to the rubber seal and it went away for good.
