If you’ve already started researching how to remove leaf spring bushings, it’s highly likely that the vehicle is already faulty.

 

It might have been the unusual noise when passing a speed bump.

Perhaps it was just a slight shake.

In the worst-case scenario, the leaf spring bushing has cracked.

 

Don’t rush into action. Before replacing any leaf spring components, first secure the vehicle properly: fully unload the suspension system and support the frame with a jack stand—ensuring no weight is applied directly to the springs.

adapters of various diameters

high-power spraylights

long-handled ratchet wrenches

heavy-duty punches

The night before preparing to remove the leaf spring bolts, spray a penetrant lubricant thoroughly onto them. This step will save you at least half the effort the next day.

 

 

rubber bushing

A rubber bushing typically consists of three layers:

Outer rubber layer

metallic sheath

Some even come with a casing.

 

For pure rubber types, the steps are relatively simple:

First, remove the connecting bolt to expose the bushing.

Then use a blade or drill bit to destroy the rubber section and remove the central metal part.

For the remaining rubber rings, sometimes they can be gently knocked out (note: knock rather than smash) by applying even pressure in circular motions to gradually loosen them.

At this point, the component can essentially be removed. During the process, care must be taken to avoid damaging the spring eye, as deformation of the spring eye is far more severe than losing a bushing.

 

 

Steel shell bushing

Some heavy-duty leaf springs employ bushings with steel strip casings—a design that is virtually impossible to produce through brute force.

 

For bushings with steel shells, a specialized leaf spring bushing press is required: typically consisting of a long screw rod and two sleeves that simultaneously push out and receive the component.

 

We need to “squeeze” it out rather than “knock” it out: the key is to apply pressure gradually. When you hear a “bang,” that’s essentially a sign of success.

 

If the spring cannot be extruded—indicating it is jammed—you may consider heating it: use a gas torch with precisely controlled temperature to heat the center of the bushing. The goal is not to red-hot the steel plate but to soften the internal rubber. Note that overheating the leaf spring steel may significantly compromise its material properties.

 

When should you stop?

Sometimes, during the disassembly process, you may discover issues extending beyond just the bushing—for instance, the spring eye has become worn and deformed or subtle cracks have emerged. In such cases, it’s no longer merely a matter of removing the leaf spring bushing; simply replacing the bushing cannot resolve the structural issue.

 

 

Some of our experiential insights

If the leaf spring bolts are worn out, it is best to replace them all at once.

When installing the new bushing, lightly lubricate the outer wall, but avoid using excessive grease.

During installation, it is best to keep the components level and avoid tilting them.

Don’t think you can solve everything with just a hammer.

 

 

One last thing to say…

5 to 8 years is a common replacement interval, depending on the load and environment.

If you’re unsure whether your tool is suitable or unclear about the spring’s condition, feel free to consult our technical advisors. Often, the issue isn’t limited to the bushing; sometimes an entire leaf spring may need replacement.
