As you steer your car you are rotating a steering wheel. That steering wheel is connected to a steering shaft, which transmits your steering inputs to a power steering gearbox. This gearbox uses the hydraulic pressure from the power steering pump to move the steering gear. The steering gear moves the pitman arm to the left and to the right. The pitman arm is attached to your center link and also moves back and forth with your steering inputs. At each end of the center link there are tie rod ends that connect the center link to the spindles. The tie rod ends are sometimes called track rod ends. Over time the tie rod ends can wear out from all the steering and suspension movement. When a tie rod end wears out the spindle is allowed to wobble while the car is in a turn under load. This can cause a vibration in the steering wheel and uneven tire wear.

These fasteners are going to be tight and there may not be a lot of room to swing the wrench. You are going to have to be patient and use some force to remove fasteners and components to rebuild your front end. Corrosion may hold a component in even after you have loosened a fastener. Keep in mind the joint may pop out when you use a removal tool so keep your hands clear and wear protective gloves.

Lift and support the front axle of the vehicle. You have to remove the tires to perform this job, and it does make access much easier since you may not have access to an automotive lift. See our tech article on jacking and supporting your vehicle properly for removing the front tires.

The tie rods on a vehicle do exactly what their title describes; they are rods that tie the steering rack to the steering knuckle. The rod has two ball joints on each end. These ball joints wear over time creating free-play in the steering, which can lead to tire wear and an undesirable steering feel. The rubber boots protecting the ball joints on the tie rod ends also can get damaged, rip and dry out over the years allowing the grease inside to escape and causing the joint to fail. You can replace the inner and outer separately. Just be sure to have your vehicle aligned once complete. To inspect, jack up the front of your vehicle and wiggle the wheel in both directions of the steering axis. Take note of any free-play. If free-play is felt, repeat the wiggle test while holding the outer tie rod. If no free-play is felt in the outer tie rod end locate the inner tie rod and repeat the wiggle test.

Remember that your car may have been serviced before and had parts replaced with different size fasteners used in the replacement. The sizes of the nuts and bolts we give may be different from what you have so be prepared with different size sockets and wrenches.

Before you do any work on your car it is important that you wear safety glasses and work gloves. If you have to jack up your car, make sure to use jack stands and chock your wheels as well as applying the parking brake. Protect your eyes, hands and body from fluids, dust and debris while working on your vehicle. Never work on your vehicle if you feel the task is beyond your ability. Always disconnect the battery before working on your car.


Lift and support the front axle of the vehicle.

Lift and support the front axle of the vehicle. Place a jack stand under the lower control arm. You have to remove the tires to perform this job, which makes access much easier since you may not have the use of an automotive lift. See our tech article on jacking and supporting your vehicle and removing the front tires. 

I placed a jack stand under the chassis as well.
Figure 2

I placed a jack stand under the chassis as well. These pictures are of the passenger side of the vehicle. It is recommended you replace both sides at the same time to keep your handling neutral. Placing a jack stand under the chassis provides additional safety.

The tie rod is connected with a crown bolt held in place with a Cotter pin.
