Tie rods are attached to the steering rack and play a critical role in helping push and pull the front tires as the steering wheel is turned. There are two tie rod ends, the inner and outer, which connect to the steering knuckle and turn the front wheels. The outer tie rod end is adjustable and is used to set a vehicle’s alignment angle. Symptoms of failed or failing tie rod end include uneven tire wear, an inability to steer, misaligned front end, and sometimes a squealing sound. If any of these symptoms are present in your car, truck, or SUV, call Direct Truck & Auto Repair in San Bernardino at 909-746-0188, or schedule an appointment online.
