Slight vibration with reverse engaged and brake pedal pressed

Slight vibration when in reverse and brake pedal is pressed at complete stop. But backing up no issue at all no vibration or noise. Anyone have this issue, I looked around and didn’t see anything related to this exact vibration.

Oasis report shows valve body was replaced in 2021, e clutches replaced valve body was cleaned all done in 2022, also pinion bearings and ring and pinion replaced all seals and pinion cups new carrier bearings axle bearings and seals dome also all done because of truck shifting from 9th to 10th gear causing truck to go into limp mode. This was all done because of the initial issue of the slipping gear in 2022
