Leaf springs are critical components of your vehicle’s suspension system. As a result, they must be maintained on a regular basis in order to function properly. Lubrication is one method of keeping leaf springs in good condition.
Leaf springs can be lubricated with a variety of lubricants. Lubricating a leaf spring reduces friction, which can cause wear. Lubrication also prevents leaf springs from squeaking.
A popular choice is white lithium grease. This post will go over whether it is safe to use white lithium grease on leaf springs, as well as its effectiveness, drawbacks, and other information.
Is White Lithium Grease Appropriate for Leaf Springs?
Many automotive experts use white lithium grease to lubricate vehicle suspension, including leaf springs.
Even though modern vehicles do not require oil lubrication, white lithium grease can reduce squeaking caused by leaf springs. As a result, white lithium grease is appropriate for use on leaf springs.
Please remember that there are many different types of lubricants, including those made of silicone. The lubricant you use on your leaf springs will be determined by your personal preferences and previous experiences.
What Exactly Is White Lithium Grease?
Before we determine whether you can use white lithium grease on leaf springs, we must introduce this lubricant.
White lithium grease is a high-performance lubricant that can be used on various surfaces. It comes in the form of a spray can, which makes application a breeze. White lithium grease is an excellent metal-to-metal lubricant, particularly for leaf springs.
The key ingredient, lithium, acts as a thickener, holding the oil in place while releasing small amounts as needed. White lithium grease is available from a variety of manufacturers. A good example is WD40.
White lithium grease is water resistant and can withstand temperatures of up to 130 degrees Celsius, among other things. It provides long-term lubrication and is extremely dense, which means it will not run.
Is There Anything Wrong With Using White Lithium Grease On Leaf Springs?
Because white lithium grease is a great lubricant, it can eliminate squeaks and annoying sounds on leaf springs. The main disadvantage of using this lubricant is that it attracts more dust.
Because of their location, leaf springs are constantly exposed to dirt. The formula of white lithium grease is intended to attract dust. When this occurs, you will only receive a temporary fix for your squeaky leaf springs.
What is superior to white lithium grease?
While white lithium grease works well for squeaky leaf springs, the fact that it tends to attract dust renders it unsuitable as the best solution.
Dry lube is an excellent alternative that will not attract dust. One advantage of dry lube is that it does not attract dirt or dust. That implies it will lubricate your leaf springs, and you won’t have to worry about dust getting in the way.
Cleaning Leaf Springs vs. Using White Lithium Grease
Your leaf springs may become squeaky if you frequently drive on muddy or sandy roads. This is due to sand and dried mud particles.
Some car owners suggest cleaning the leaf springs to alleviate the squeak. Others will advise you to coat them in white lithium grease. Both options are important; they should be used in tandem rather than comparing them.
A dirty leaf spring cannot be cleaned with white lithium grease. First, it must be thoroughly cleaned. You can use a pressure washer to clean it and then let it dry. If you need to apply the white lithium grease quickly, use a pressurized air sprayer.
When you only clean the leaf springs without lubricating them, they will become dirty. This is why they must be cleaned and lubricated on a regular basis. White lithium grease, on the other hand, attracts more dust, which isn’t suitable for your leaf springs.
What is the shelf life of white lithium grease on leaf springs?
This is determined by the type of terrain in which you frequently drive your car. Within three months, white lithium grease will have attracted and bonded to dust if you are an off-roader.
Using white lithium grease to deal with a squeaky leaf spring will only provide temporary relief. It is best to use a lubricant that repels rather than attracts dust. That way, you’ll have a permanent solution for squeaky leaf springs.
Is White Lithium Grease the Only Way to Repair Squeaky Leaf Springs?
Aside from squeaks that result from friction in the leaf springs, there are two other contributing factors of noisy leaf springs. The first offender has overtightened shackle bolts. This can be avoided by screwing the bolts gently but not tightly.
The other possible cause is loose U-bolts. The inverse of a shackle bolt. This must be tightly tightened, and you will have eliminated any squeaks.
If you still hear squeaks after tightening and lubricating the shackle bolts and U-bolts, the squeaks are coming from somewhere else.
You must understand that leaf springs are not the only mechanical component that can cause squeaks. There are also numerous lubricants on the market. The decision to use white lithium grease is more of a personal one. You can use silicone or other substitutes.
What’s the Deal With White Lithium Grease?
White lithium grease is used on leaf springs for a variety of reasons. The first reason is due to its lubricating properties.
White lithium grease will lubricate and prevent squeaks on your leaf springs caused by metals rubbing against one another.
Another reason to use white lithium grease is its ability to penetrate leaf spring crevices. It flows into difficult-to-reach areas and lubricates those parts when sprayed.
Aside from the benefits listed above, white lithium grease prevents rust and forms a protective coating that extends the life of your leaf springs.
Unfortunately, white lithium grease attracts dust. If it didn’t, it’d be the best lubricant for your leaf springs.
What Is the Best Way to Spray White Lithium Grease on Leaf Springs?
As you might expect, spraying white lithium grease on leaf springs is a simple task. The majority of white lithium grease products are sold in aerosol spray cans. The convenience of storing such a liquid in a spray can make application relatively simple.
The first step is removing dirt or dust from the leaf springs. You don’t have to look hard to see how filthy the leaf springs are despite many people skipping this step and spraying the white lithium grease directly. That is not a good idea.
Cleaning is critical because it facilitates the work of the white lithium grease. To begin, use a pressure washer to thoroughly clean the dirty leaf springs. Allow it to dry before applying the white lithium grease.
The leaf spring does not need to be disassembled. Get underneath your truck, find the leaf springs, and begin spraying. Don’t be concerned about difficult-to-reach areas.
Because of the formulation of white lithium grease, it will lubricate and penetrate any crevices. Allow some time for the white lithium grease to settle after spraying it, and then test to see if you can hear any squeaking.
Is White Lithium Grease Harmful to Leaf Springs?
As a car owner, you understandably have reservations about which products you should or should not use. There’s no need to be worried about white lithium grease causing damage to or negatively impacting your leaf springs.
White lithium grease, on the other hand, has the opposite effect. It lubricates the leaf springs to improve performance and protects them from corrosion. As a result, you don’t need to be concerned about spraying white lithium grease on your leaf springs.
