AE86 top mount

[totta Crolla]

For anyone interested it is possible to change the bearing in the standard rubber top mount.
Basically it just presses out from the top nut side. At first I used a 6 ton press and it was not enough pressure but a 20 ton press made it look easy.
The bearing pushes through a folded over flange and whilst Toyota will have had some sort of shaped die to originally press the flange it can successfully be gently hammered back into place after a new bearing is pressed in.
Only real issue is finding a strong enough tube to put around the outside of the bearing when pressing it out. I used a large socket. The outer 'cup' shaped part is not strong enough to withstand the pressure. Bearing is 42x15x13mm od / id / w
Hope the info helps someone.
