regardless the problem is from mounts or not get them changed with new ones , either oem honda ones or the best first copy (thailand) dont go for anything else , any rubber part that goes into the car should be changed with new , its plain stupidity (please dont mind) to put used bushes and mounts, change them today or u will have to change them tomorrow either way and in between u will keep having problems like u are having , the best approach is spend a little cash one time , if the bushings in ur link arms are bad change all the bushings right and left , even the ones that seem fine to you, alongwith ball joints , once these things are renewed u will feel that the buttery smooth drive civics are known for, because all these parts damp out and share eachothers vibrations, basically they support eachother if u replace one and leave the other u wont get the result and if u put good oem parts i can gurantee u that till the time u have this car u wont need to get any work done in ur suspension. moreover ur car is old so the rubber parts are already due for replacement doesnt matter the km car has run , rubber parts have their life.
