I took the car into the shop today because i was having some weird steering issues.They informed me it needed to have the steering rack replaced.Ok i got that.Now comes the i dont know questions.Upon looking at this part on line some sites refer to the rack and pinion.When i buy the rack the pinion is automatically a part of this?I dont need to buy this seperately?One site had choice of a magnasteer rack and a normal rack,whats the difference?Will either fit?And last question.Many of these had a core charge,so if the item is $175 and the core is $50 does that mean i have to pay $225?I understand i would get the core back once i ship back.OH DAM!another question now.If i have to ship a core back wont that come out of my pocket in shipping or will they cover that?
