Why Does My Truck Sound Like A Squeaky Bed?

A relatively common source of a truck sounding like a squeaky bed is dry sway bar bushing. Take note that sway bar bushings are vital components in a car’s suspension assembly. It helps stabilize the vehicle, particularly as it turns.

However, sway bar bushings need proper lubrication. The lubricant can wear out over time, causing a squeaking sound.

On the other hand, the entire suspension assembly might also be at fault. That squeaking noise can be an indicator that your truck’s suspension is about to go out. Take note that this assembly can malfunction or break down because of different reasons, such as:

  • Misaligned tires
  • Uneven tire wear
  • Faulty steering rack
  • Stuck brake caliper

Troubleshooting your truck can be the first step to diagnosing and verifying the origin of this squeaking sound. Still, prepare yourself as you might have to replace your truck’s suspension to remove this noise and to make your rides safe.

Suspension maintenance

Like relatively any automotive repair job, make sure to practice proper safety protocols before proceeding with the solutions highlighted in this section. Some safety guidelines you should be following are:

  • Turn off the engine and allow it to cool down before starting the repair job.
  • Ensure that the parking brake is on at all times unless you need to release it for specific reasons.

Lubricate The Suspension’s Sway Bar Bushing

Warning: Don’t use the standard WD-40 product in an attempt to lubricate sway bar bushings. Although it has some lubricating properties, it displaces water and can bring more harm than good to the suspension over time.

Instead, use the items listed below and follow the succeeding steps to lubricate your truck’s sway bar bushing properly:

What You’ll Need

  • Car jack
  • Wheel chocks
  • Wrenches (e.g., wheel, socket, and liquid)
  • Microfiber towels
  • White lithium grease

Step-by-Step Guide

  1. Turn on the engine and drive the truck for a short distance to diagnose the location of the faulty sway bar bushing.
  2. Return and park the vehicle in a safe location.
  3. Place chocks on the wheels that’ll stay on the ground.
  4. Lift the car with the jack. Ensure that the area that you’re lifting is the one with the faulty sway bar bushing.
  5. Use the appropriate wrench to remove the lug nuts on the wheel assembly that’s covering the dry sway bar bushing.
  6. Pull the wheel assembly out of the vehicle and set it aside temporarily.
  7. Apply white lithium grease on the dry sway bar bushing according to the manufacturer’s instructions.
  8. Return the wheel and lower the vehicle safely.

  4. Loosen the lug nuts on the wheel covering the suspension that you’ll be replacing.
  5. Take out the wheel to expose the suspension assembly.
  6. Find and remove the damaged component.
  7. Replace that part with a new unit, which should be in the suspension kit.
