I've been getting a lot of clunking and looseness in my front end on rough roads recently. I thought it was in the suspension, but everything seems fine. I'm thinking it might be in the steering somewhere. If I'm at a stand still and move the steering wheel a little from left to right, I can here a little clunk every know and again in the steering rack. I don't know anything about steering racks. Are there bushings in the steering rack that can be replaced?
