Front-End Work

Rack-and-Pinion: Many modern vehicles use a rack-and-pinion steering system that allows you to turn your front wheels. In this system, the steering wheel is connected by a shaft to a pinion, which is connected to a rack. In turn, the rack connects to tie rods which connect to other parts of the steering system. When you turn the steering wheel, you turn the pinion in the same direction, which causes the other parts to turn in that direction. Problems with parts in a rack-and-pinion system can lead to trouble steering and irregular tire wear.

Tie Rod Ends: In a rack-and-pinion steering system, tie rods connect the steering rack with the steering knuckles. When you turn, the steering rack slides and causes the tie rods to turn the steering knuckles. They are responsible for transmitting force from the steering rack to the wheels. A tie rod is comprised of two parts: the inner tie rod and the outer tie rod. Both are protected by a plastic or rubber cover known as a boot. Over time, tie rods may become loose or suffer from corrosion if their boot cracks. A separated tie rod causes a loss of steering control. You may also hear rattles or clunks.

Idler Arms: The idler arm assists with pivoting and supports the center link. It is located across from the pitman arm and responsible for steering on the passenger side of a vehicle. An idler arm can become damaged from rough driving and over time from regular wear. If you hear noise under your vehicle or find yourself being pulled to one side, you may have a problem with an idler arm.

Pitman Arms: A pitman arm is a support part that connects the steering box with the center link. Pitman arms are located across from idler arms and assist when turning the wheels. A loose pitman arm can result in poor steering and your vehicle having a tendency to drift.

Ball Joints: Front end ball joints are responsible for connecting the wheels to your steering and suspension system. Specifically, these ball joints link your steering knuckle with the control arm. If you hear clunks or notice your tires wearing at an uneven rate, you may have a problem with the ball joints.

Shocks or Struts: Depending on your vehicle, you'll have shocks or struts (or one type in the front and one type in the rear). Both play an important role in driving comfort, absorbing the bumps of the road so you don't need to feel them as intensely. They also help with overall vehicle control. If you have a problem with your shocks or struts, you'll likely feel the difference. You may also feel vibrations in the steering wheel.

Wheel Bearing and Replacement: Your wheel bearings connect to the hub and reduce friction while your wheels spin. They're built to be durable but aren't impervious to damage. If you hear noise near your wheels that increases as you drive, then you may have a problem with your a wheel bearing.

Coil Spring Replacement: A coil spring (also known as a compression spring, helical spring, or torsion spring) is a part of your shocks and/or struts. Its purpose is to absorb impact from when your tires and wheels roll over the ground or other terrain. It's thanks to your coil springs that there is less bounce when you drive. As such, you may have a problem with a coil spring if you suddenly notice more bounce or hear noises from underneath your vehicle
