so today i finished changing the guide rod bushing, i removed the caster bucket replaced the bushing inside with alot of frustration, so the new caster nucket is ready to put in, but im having alot of trouble puting this back on. do i need to remove the guide rod that attaches itself to the lower control arm? is that nessasary? and if so how can this be done? i tried hard and it wont budge. any advise?
