Rear trailing arm bushes W126

[quaid]

Hi,

I just took delivery of some K-Mac adjustable rear trailing arm bushes for my W126.

I Emailed K Mac to discuss the fitting of these, and they reckon I need to pull the entire arm from the car to push out the old bushings.
The WSM shows a tool being used to pull them out, which looks like it could be done with the arm still on the car.

Has anybody attempted using a 'clone' of this tool, i.e. a couple of pieces of tube, some washers and a long bolt?

Any other tips for removing these while still on the car?

Cheers,
Ben.
