I have a 2003 Sport Trac and I noticed that the vehicle tends to pull to the left. I recently had new tires and an alignment done and my truck still pulls to the left. I took my front side drivers wheel off and I noticed that I had a frozen brake caliper sliding pin. I just purchased a new caliper bracket and sliding pins and I'm hoping this will resolve the issue. If this doesn't do you guys know what could be causing my truck to pull to the left? Thanks
