Ford Mustang V6 and Mustang GT 1994-2014: Why is My Frame Squeaking?

Aren't you tired of that mystery squeak coming from your car? Silencing the squeak is not as hard as you may think it is, here is how to do so.

This article applies to the Ford Mustang V6 and Mustang GT (1994-2014).

No one likes to hear a random squeak when they're trying to drive into their oasis. The reality is, it is really hard to pinpoint where a squeak may be coming from, especially if it only occurs when the chassis is under a specific load. However, we can still direct you to some very common causes of chassis squeaks on your vehicle. Use the following diagnostic article to help pinpoint the location of the squeak.

Materials Needed

  • Flashlight
  • Jack stands
  • Jack
  • Gloves

Step 1 – Check your lower control arms

The bushings might be dry.

This is by far the most common cause of a squeaking chassis. The bushings that are placed in-between the control arm and chassis mounting location will often dry out, causing it to squeak every time the car drives over something uneven. You can inspect this area by raising the rear of the chassis off the ground and securing it in place. Push the tires up and down to see if there is any noise that can be heard from the bushings. If the noises are apparent, you can either lubricate the bushings for a temporary fix or replace the arms with new parts.

Step 2 – Check your exhaust hangers

The hangers might be rubbing on the chassis.

This is another common problem found on most Mustangs: the hanger under the chassis isn't solid and instead hits against the frame while the car is in motion. This creates a squeaking noise heard mostly while the car is accelerating. The hangers most commonly responsible for the noise are found above the muffler. To remedy this problem, place a thick piece of rubber onto the hanger and zip tie it in place. This should deaden the sound.

Step 3 – Check your sway bar end links

They may need to be tightened.

The end links mount your sway bar to the chassis. They are special parts made up of a bolt, nut, bushings and several washers that help stabilize the car and reduce its body roll. When the locking bolt is a little too loose, the car will squeak when driven on any type of rough terrain. This is a quick and easy fix that only requires you to torque the end link all the way down.

Pro Tip

If the bushings also look dried out, take the time to grease them. This will help prevent future noises from appearing on the car.
