Is White Lithium Grease a Suitable Lubricant for Leaf Springs?

Many experts in the auto industry use white lithium grease to lubricate their vehicle suspension including leaf springs.

Even though modern vehicles don’t require oil lubrication, white lithium grease can eliminate squeaking produced by leaf springs. Therefore, white lithium grease is suitable for use on leaf springs.

Please note that there are many types of lubricants, including those made out of silicone. The lubricant you should use on your leaf springs will depend on preferences and previous experiences.

What is White Lithium Grease?

Before going much further with our review on whether you can use white lithium grease on leaf springs, we need to introduce this lubricant.

White lithium grease is a heavy-duty lubricant that can be used on a wide range of surfaces. It is available in a spray can, which makes the application pretty straightforward. White lithium grease is an excellent lubricant for metal-to-metal applications such as leaf springs.

Lithium, the key ingredient, acts as a thickener that holds the oil in place while releasing small amounts when needed. Many brands make white lithium grease. WD40 is a good example.

Some of the key properties of white lithium grease are that its water resistant and can withstand temperatures up to 130 degrees Celsius. It offers long-term lubrication and is highly viscous, meaning it will not run.

Are There Any Drawbacks of Using White Lithium Grease on Leaf Springs?

White lithium grease on leaf springs can eliminate squeaks and annoying sounds since it’s a great lubricant. However, one main drawback of using this lubricant is that it attracts more dust.

Considering where leaf springs are located, they are exposed to a lot of dirt daily. The white lithium grease formula is designed to attract dust. When that happens, you will only benefit from a temporary fix to your squeaky leaf springs.

What’s Better than White Lithium Grease?

Even though white lithium grease is effective in dealing with squeaky leaf springs, the fact that it attracts dust disqualifies it as the best solution.

If you want an alternative that won’t attract dust, kindly go for dry lube. One of the perks of using dry lube is that they do not attract dust or dirt. That means it will lubricate your leaf springs, and you will never have to worry about dust interfering.

Using White Lithium Grease vs Cleaning Leaf Springs

If you often drive on muddy or sandy roads, your leaf springs can become squeaky over time. That’s because of the sand and dried mud particles.

To deal with this squeakiness, some car owners recommend cleaning the leaf springs. Others will tell you to spray them with some white lithium grease. Both options play a critical role; instead of comparing them, they should be used together.

You can’t spray white lithium grease on a dirty leaf spring. First, it must be cleaned thoroughly. You can use a pressure washer and let it dry. If you are in a hurry, you can use a pressurized air sprayer and apply the white lithium grease.

When you just clean the leaf springs and fail to lubricate them, they will get dirty. This is why they should be cleaned and lubricated. Unfortunately, white lithium grease attracts more dust which isn’t ideal for your leaf springs.

How Long Can White Lithium Grease Last on Leaf Springs?

That depends on the type of terrain you frequently drive your car in. If you are an off-roader, white lithium grease will have attracted and bonded to a lot of dust within three months.

You will only get temporary relief from white lithium grease if you are using it to deal with a squeaky leaf spring. It’s advisable to use a lubricant that repels instead of attracts dust. That will ensure you get a permanent solution for squeaky leaf springs.

Is White Lithium Grease the Only Fix for Squeaky Leaf Springs?

Besides squeaks caused by friction in the leaf springs, there are two other causes of noisy leaf springs. The first culprit is shackle bolts that have been tightened too tight. That can be avoided by gently screwing the bolts without tightening them.

The other cause is loose U-bolts. The opposite of the shackle bolt. This needs to be firmly tightened, and you will have gotten rid of any squeaks.

If squeaks are still being produced and you have correctly tightened the shackle bolts, U-bolts, and lubricated, then the squeaks are coming from elsewhere.

You need to understand that the leaf springs aren’t the only mechanical part that can produce squeaks. Also, there are many lubricants on the market. Deciding to use white lithium grease is more of a personal decision. You can use silicone or other alternatives.

What’s So Special about White Lithium Grease?

People use white lithium grease on leaf springs for a couple of reasons. The first is because of its lubricating properties.

White lithium grease will lubricate and prevent any squeaks on your leaf springs that are being produced when the metals rub against one another.

The other reason you should use white lithium grease is its ability to penetrate crevices in the leaf springs. When sprayed, it flows into hard-to-reach areas and lubricates those parts.

Unfortunately, white lithium grease attracts dust. If it didn’t, it would be the best lubricant for your leaf springs.
