Your Truck's Wheel Balance and Front End Alignment

Is it a wheel balance problem or an alignment issue?

By , About.com Guide

You're driving your truck and you notice that it doesn't feel right, so you take it to the local repair shop and request a front end alignment. Later, you pick up the truck and are unhappy with the shop because it still has the same problem.

That scenario is more common than you might think, because people often assume they know the solution to a problem and ask for a specific service, instead of describing the symptoms as completely as possible and allowing the technicians to make a proper diagnosis.

The wheel balance and alignment tips below will help you pinpoint what your truck is doing so that you can convey information to your repair person. The possible solutions are a guide to help you understand your vehicle, and shouldn't be used to make a diagnosis.

Constant shake or vibration at all speeds

  • Bad tire
  • Bent wheel

Constant shake or vibration at specific speeds or ranges

  • Out of balance wheel or wheels

Vibration when you hit a bump

  • Worn or loose steering or suspension parts
  • Loose front wheel bearings

Constant steering wheel vibration

  • Problem in the front wheels

Constant vibration in the seats

  • Problem in the rear wheels

Pull or Drift
Incorrect tire pressure is the most common cause of pull (vehicle wants to go quickly to the left or right) or drift (a gradual direction change).

Radial Tires
Do you have a consistent pulling to the right or to the left? You might have radial pull, which can occur anytime, even with new tires. If you have the ability and tools, try switching tires side-to-side (left side tires with right side tires). If the pull changes directions or stops, you're dealing with radial pull.

Steering Alignment or Worn Parts
If the alignment is out of spec or you have worn steering components, the vehicle will pull or wander (when you must constantly correct to the left and right).
