changing the rear shock mounts is easy.take the side inner trunks panels off first,undo the shock bolt all the way,then loosen(don't take them all the way off yet) the two rsm bolts on the side that you want to do first,jack that side up,and then loosen the two rsm bolts all the way.the rsm should just pop out(might need alittle force).if you have any aftermarket suspension stuff,or bigger wheels than oem,think about the rsm's with replaceable mounts.
