2004 g35x...took to dealer last week for some warrant work. they said the front compression rods needing changing....they did the replacement for free under warranty. they even did a free babalce and rotation. after picking the car up, it didnt feel right. the steering wheel felt kinda loose. wasnt as tight as it was before. driving home on the highway the car vibrating around 85 mph and the front end felt unstable at that speed. took the car back on monday and they moved the tires back to where they were and re balanced them. steering wheel is still loose and the steering is really touchy. should the dealer have done an alignment after changing the compression rods? they are telling me the problem is with the tires....but somehow i dont believe it.
