middle bearing that support the driveshaft

[mindus]

a new bearing was 'installed' in the basically original bracked with a very stiff rubber surrounded (similar to polyurethane, but way stiffer). The rubber part was machined to be able to install bearing and then beck to the bracket, which was modified sligtly.

I also renewed my centre bearing using the urethane method - I simply cleaned the rubber surfaces of the bearing and packed both sides with urethane. It has worked very well and this method costs almost nothing. As long as you have a bearing and the metal surround of the original setup you can use urethane to make a rubber surround from scratch. It is much stiffer than the original - without being completely rigid...

You could simply get the original surround and place it flat on a bench with the rubber removed - then put the new bearing centered in the middle of the surround and fill with gap with urethane.
