Thanks for heads up. Something easy to check and fix.

Agreed. I had my left half shaft replaced a few months ago... leaking. 9km miles too.

I recommend that you edit your thread title to something like, "New GM TSB Document - Possible Leaking Half Boot on 2021-2025 Models", as the inclusion of 'TSB' will quickly get members attention for those model years.
