Car is a 97 honda civic Ex coupe. engine and trans is 1999 JDM b18b. I am wondering if my axles are wrong or the diff is messed up because if you grab the inner joint on the passenger side at the trans you can move it up and down. seems to be excessive. i have a vibration ive been fighting for a while from 25 to 35 and from 70 and up. The drivers side where it goes into the intermediate shaft has slight play as well. the vibration seems to be felt alot on the drivers side but im wondering if the problem lies in the diff due to the play in the passenger side. please help
