Trying to replace bushings on rear trailing arms

Group,

I posted this question yesterday but that post has dissappeared unless I'm dreaming......wonder where it went?

Anyone know steps to replace the rubber bushings that connect the rear trailing arms? There are four points where the arms tie in and at each point, there are two bushings (one on each side).

It looks like I will need to lower the subframe to get at two of the pivot points. I'm just not certain how to proceed with that. Someone advised that springs would have to be compressed as with work on front suspension but I hope there is a way to do it without that complication.

Thanks,

Nic
