Removing suspension bushes part 2

The inner ‘Flambloc’ bushes can be pulled out with a similar technique as the outer ones. My rear inner bushes were in a really bad state; some of the rubber was literally falling out!

These bushes definitely need replacing

The first job is to cut the end off the old bush. If the end is not cut off, the rubber inside deforms when compressed and makes it harder to pull through the wishbone. Cutting takes a few seconds with a reciprocating saw. Make sure the cut is perpendicular so that the bush will push out straight.

Since these types of bushes are spot-welded in, the welds need to be ground off. The best tool I have found for that is a Dremel with one of these wheels:

With the welds ground off, the bush is in theory, removable. Time to assemble the puller once again using the M12 bolt, washers and the 46mm socket as the receiver. In this case an 18mm socket was the perfect size to push the newly exposed outer edge of the bush.

The old bush comes out out with very little effort:

    The posts on dealing with suspension bushes without a hydraulic press are very useful. I will use this information when I do mine.

    Are you using urethane or rubber for the replacements?

      OEM rubber silentblocs. Primarily because I found polyurethane squeaks too much but also because I don’t like how polyurethane bushings wear. The rubber silentblocs do not move or rub against any other components and so will wear better until the rubber finally perishes. And I have found that even when they looked perished on the outside, the rubber inside was often perfectly fine. The only times I think poly is the way to go is if the car is not driven or if the rubber might be exposed to fuel or oil which attack the rubber. These are the only scenarios where poly bushings outlast rubber ones.
