This thread was really helpful so thought I would share the latest information. As per the previous post, PIP5653K has been published as of April 15, 2021. It appears GM has updated the TSB to state there is currently no fix for the 'Squeak Chirp Noise from Front Axle in 2wd - SU4'. This was my second visit to the dealer. Truck is a 2019 Silverado RST 5.3L-8spd and has 33k miles. The latest TSB includes Chevy and GMC trucks from 2019-2021 and also now includes 2021 Tahoe, Suburban, Yukon and Escalade SUVs. Let's hope having the very expensive Cadillac Escalade on this list expedites GM identifying a fix for the issue.
