Gear box mount

[Piggy]

It is good to replace other mounts as well - with new only one rest two will be damaged much faster. But the one on bottom is not easy changed without press and remounting axle - probably information are in guides

Can this one be seen moving much the bottom one?

I know somebody with a press no problem.

You can do it without removal of the casing and a press... if you buy a powerflex polybush which is well worth the money as even OEM bottom bushes die pretty quick and powerflex give lifetime warranty.
