The Steps Professionals Take for Wheel and Headlight Alignment

headlight alignment

What is an Alignment?

An alignment is usually defined as a procedure performed by a professional and experienced mechanic to get your car’s suspension back into its proper form. A professional mechanic usually recommends the correct type of alignment for your vehicle by inspecting its current condition. 

Different types of car alignments 

There are four main types of car alignments. The type of suspension your vehicle is suffering determines what kind of alignment your car needs. 

  1. Front-end alignment 
  2. Headlight alignment 
  3. Thrust alignment 
  4. 3D wheel alignment 

In this article, we will see the steps that professionals usually take to determine correct headlights and wheels alignment. 

Step-wise Procedure for Proper Headlight alignment

A professional usually follows the below-given procedure for proper alignment of a car’s headlight: 

  1. First of all, he checks the level of your car, ensuring that all tyres have the same pressure.
  2. Next, he parks your car on level ground in the tyres centre or a garage, almost 10 to 15 feet away from a dark wall.
  3. After that, he turns the car’s headlights on. And mark both the vertical and horizontal centerlines of the light beams falling on the wall. That with the help of a masking tape.
  4. Then he places a carpenter’s level exactly between both marked center lines to check if they are on the same level or not. If not even, then he measures the difference between the heights.
  5. Then he parks back your car 25 feet away from the garage door or dark wall exactly. Turn off the headlights and determine the location of adjusting screws.
  6. After that, he adjusts each headlight separately by repeatedly turning on and off the front headlights.  
  7. Next, he turns the upper screw or bolts clockwise and anticlockwise to adjust the headlight’s fields properly.
  8. After vertical alignment, he turns the side bolts or screws to set the horizontal field similarly.
  9. The light pattern made of the wall helps you determine correct headlight alignment.
  10. Finally, he takes out the car for the test drive and tests the alignment on the road.

3 reasons why wheel alignment is needed

To stop the vehicle when swerving to the side
To avoid overdue wear on tires and steering and suspense factors
Eventually, insure excellent stability on the road.

What Causes Wheel Alignment Problems?
Alignment problems are substantially caused by wear on the suspense and steering factors.

They can also be the result of an impact in a pothole or wind or unforeseen gear changes due to a veritably low or veritably high suspense.

Still, there’s a possibility that the wheel alignment is incorrect, If the vehicle veers to the side of the road.

Still, the alignment of the front and hinder bus is presumably incorrect, If the steering wheel is in the wrong position when driving straight ahead.
A wheel alignment must be carried out

After serious driving incidents.
After the vehicle has faced a major hazard or wind in the road.
Failure to perform wheel alignment procedures may affect in camber and toe specifications exceeding the manufacturer’s limit. In turn, this can beget the vehicle to drift and unseasonable wear of the suspense factors and tires.

Tire wear leads to frequent tire relief and drift leads to unseasonable wear of suspense factors, all of which add gratuitous expenditure to the proprietor.

Make sure a complete wheel alignment procedure is carried out duly and to specialized norms once the steering and suspense element reserves are completed.

Step-wise Procedure for Correct 3D Wheel alignment

For the most accurate wheel alignment success, a tyre professional usually follow the below-given procedure:

  1. First of all, he raises your vehicle in the air on a two-post lift. And then, under all its four wheels, place Absolute Alignment’s wheel alignment stands.
  2. Secondly, he removes the turn plate pins and locks the car brakes to bounce the vehicle, ensuring that it has returned to its normal ride height.
  3. After that, he attaches wheel clamps and wheel alignment heads to all four wheels, ensuring a good fit on the wheel rims.
  4. Then, he checks the vehicular manufacturing manual to know the target data and its full 3D wheel alignment specs.
  5. In the very next step, he levels the Bluetooth alignment heads and straightens the steering wheel entirely.
  6. After that, he alternatively turns the steering wheel 10o to the right and left side, freely allowing the wheel aligner to record the caster keenly.
  7. Having your vehicular wheel alignment data live on the screen through Bluetooth heads allows him to show any alignment faults.
  8. Soon after that, he adjusts all the different out-of-specification angles of your wheels into the green segment of the wheel alignment services screen. That generally helps you return your car to correct manufacturer tolerance.
  9. Lastly, he saves the aligner information for future reference.
  10. That print will also help you keep a complete record of your car’s remedial work in the long run.
