i have a slight vibration at about 65-70 mph. i was going to take the car in for an alignment. but im waiting to get my new rims and tires on first (it does pull a little). now the vibration is noticable but bearable. and seems to go away if i drive thru it. my question is should i check anything else b4 i get the alignment done? is there anything i should look into like drive shaft or u joints or something? any advice would b great-
