Why does your 1992 previa shake after replacing ac comp?

If your 1992 Toyota Previa shakes after replacing the AC compressor, it could be due to improper installation or misalignment of the compressor, leading to vibrations. Additionally, if the new compressor is unbalanced or there are issues with the mounting brackets, it can cause shaking. Another possibility is that the serpentine belt may be misaligned or worn, which can also lead to vibrations. It's advisable to double-check the installation and ensure all components are securely fitted.
