New thrust arm bushings still no help

[THE VEIN]

I recently was having an issue with getting a hard tump/wheel shake when driving slow and coming to a complete stop (when I'm driving in a parking lot and suddenly see somebody coming out) I never had any type of vibration at any speed

I took it by a shop and was told I need to replace both trust arm bushings and ball joints so I did about 2 months ago and now I noticed the same feeling is back again

This is my first x5 and first bmw and I feel like this shop too advantage of me so I wanted to know what could be causing this so I know better when going back
