Hi
I took the car to a shop. They removed and replaced the bushings, bolts and nuts. To do 4 big sub-frame bushings, lower control bushings at both ends, welding with undercoating, and new eccentric pins with new bushings, and a wheel alignment cost me 13.5 hours labour.

All 3 bushings on each eccentric pin, had to be pressed in, the fit is too tight to install them, while on the car.
