to do a steering rack replacement on 2 wheel drive model is 658.86 parts and labor, you will also need a alignment, that runs 79.00
the reason I ask I HAD MY OIL CHANGED AND I think they just looked at the mailage 73000 so how could they tell if anything is wrong I don't have a problem steering. What problems should I have if it is the steering gear as they told me.
