Hello, since there is a dearth of videos showing the replacement of rear suspension bushings on the 740, I have created a videolog of my job. It is relatively easy if you have some time and a press. I replaced the panhard bushings, torque rod bushings and trailing arm bushings. I did not replace the subframe bushings, though I bought them. I also replaced the shocks, of course.
I hope this helps and will encourage you to tackle this job yourself.
