Welding Leaf Springs – Is It Even Possible?

Leaf springs are essential for the smooth navigation of your vehicle. Without a stable, unbroken leaf spring, driving your car may be super-tricky.

But what happens if you have a broken leaf spring to deal with?

Welding leaf springs could be an ideal option in some cases. And if you don’t have much cash to get a leaf spring replacement, repairs could be cost-effective.

These springs are delicate and could lose their durability when not repaired the right way.

That’s why this piece provides vital information on how best to maintain your leaf springs. With all the facts this piece provides, maxing out your spring’s performance becomes less hassling.

Leaf Springs – What are They?

Designed with a slightly arched shape, leaf springs function as suspensions for wheeled vehicles. Most leaf springs follow a semi-elliptical design and allow smoother navigation across several terrains.

These springs provide absorbent support from possible wheel shocks arising from bad roads.

Leaf springs possess carbon steel, chromium, and other metals as their main component. The need for toughness and resistance to wear and tear makes these metals ideal for sustained use.

Based on the materials used in making leaf springs, they could cost a sizeable investment for replacements. Replacing leaf springs could cost between $400 to $800.

What Do You Do to Repair a Broken Leaf Spring?

Assess the level of damage

Assessing your leaf springs for issues is the first step to assuring a better repair effort. Consider checking the alignment of your leaf springs and the physical appearance of each set.

Check for broken or bent parts

If you check out your leaf springs for issues, consider their shape before anything else. Closely at the leaf spring from both sides to check out if it’s flattened out. Also, consider checking for broken leaves in the entire suspension component.

If the leaf spring is bent out of shape, you can consider using an F-tipped bar to bend it back. The same goes for leaf springs that are bent in too much.

Broken springs can be welded under the right conditions. Check out the tips below to weld leaf springs if that’s what you fancy.

Tips to Weld Leaf Springs

  • Use jack stands rated for your vehicle’s weight to keep it in shape
  • Engage proper lighting for increased visibility
  • Weld with a filler metal that shares similar properties with the leaf springs

Maintenance Checks to Elongate Lifespan of Leaf Springs


Leaf springs leverage U-bolts for a tight fit onto your vehicles’ axle. Check the bolts to see if they’re worn out and replace any bolt that can’t fit snug onto the springs.

With such simple steps, you can extend the lifespan of your leaf springs without hassle.


Older leaf spring models encourage lubrication with a wide range of oils. But newer options tend not to need excess lubing.

The best way to max out your leaf springs’ lifespan is to use silicone-based spray formula. Using such sprays will stunt corrosion and keep your leaf springs appearance sustained for longer.

Issues That Could Arise from Welding Leaf Springs

Slag build-up

During welding, slag could form at several points along your join line. If slag gets in contact with any area other than the damaged spring section, more issues could crop up.

If it becomes necessary to weld your leaf springs, consider making the join with utmost precision.

Heat transfer

Thermal transfer all through your metal springs may cause it to clamp together or warp out of shape. The leaves on this spring have to be at a certain angle to perform optimally.

Heat could interfere with the ability of leaf springs to function, affecting several aspects of vehicle navigation.

Your suspension system has a major role to play in your safe commuting through roads. Consider confirming how much heat your springs can take before initiating a join operation.

Wrong tensioning damage

During welding, some operators could think tensioning leaf springs provide a better result. But in most cases, an adverse experience is what most welders are left with.

Consider welding your leaf springs without tensioning too high to prevent an uneven shape.

Metal property changes

Leaf springs are designed with metals targeted at enhanced tensile strength for several miles.

Even if your weld goes smoothly, there’s still a chance of several factors in its composition taking a hit. Issues relating to tensile strength, resistance to wear, and general strength could be affected.


Can leaf springs be welded?

Stress risers could develop when leaf springs are welded. Consider replacing your leaf springs as the first option after prior leaf spring maintenance.

Can leaf springs snap?

Leaf springs could snap when exposed to intense pressure and poor maintenance. Car owners that tighten their leaf springs U-bolts over time tend to have longer-lasting suspension fixtures.

Can you lubricate leaf springs?

Leaf springs don’t need any lubrication to function, particularly recent models. Spraying your leaf spring with a silicone lubricant is a better option.

Do you have to replace both leaf springs?

You will need to replace both leaf springs if one gets broken, especially if your vehicle’s a bit old. But if you have a fairly new vehicle, you may not need to change both leaf springs at once.

How long do leaf springs last?

Leaf springs for standard vehicles like vans, pickup trucks, or sedans could reach 200,000 miles or more. It all depends on mileage, construction of your leaf springs, and plain luck in some cases.

Final Word

Consider replacing your leaf springs as a first course before thinking about welding them. Over time, welded leaf springs still tend to lose their toughness and encourage more complications.

Even if replacements are expensive, it’s the safest option.

Make the most of welding leaf springs information in this post. And maximize your safety with the right option. Remember, the performance of your suspension system is integral to your overall commuting safety. Don’t trifle with it.
