Benefits of Using Grease for Polyurethane Bushings

To maintain the top-notch condition of your polyurethane bushing, you need to grease it properly. Hence, let us enlighten you with all the benefits of polyurethane, so you can understand its potential.

No More Squeaky Noise

Sometimes the polyurethane bushing makes squeaky noises, which are very annoying, to be honest. So, if you are sure that your bushings are making that noise, lube it well to get rid of the irritating sound.

Makes It Water-Resistant

We all know that moisture is harmful to polyurethane bushings. That’s why getting a grease is a must. You see, grease acts as an efficient coating on these bushings. It protects the polyurethane bushings from rust and corrosion.

Protects It from the Heat

Heat can be a threat to polyurethane bushings. However, you can protect it by using a grease. If you grease the bushings, you will make them resistant to heat. In this way, the bushings will have enhanced performance and durability.

Prevent Oxidation

A coating of grease will protect the bushings from oxidation and increase their longevity. Now, that’s something you don’t see everyday, do you?

Reduces Friction

Frictions can be a bummer sometimes, and too much of it won’t let the polyurethane work smoothly. Turn the tables by using a grease then. The grease will reduce the amount of friction so the polyurethane bushing can perform smoothly without any complications.

Things to Consider Before Buying Grease for Polyurethane Bushings

Now that we’re done with the reviews, it’s time to get into the more detailed bits. Let’s talk about the different factors that come into play when choosing a grease for your polyurethane bushings.

Type of Grease

Before buying a grease, you’ve got to remember that all the greases aren’t made the same. Some bushings will need silicone-based lubricants, while others require lithium greases. So, it’s essential to find out which type of bushing you have first.

This might seem complicated, but it's pretty simple once you've gotten the hang of it. If you're looking for grease for rubber or polyurethane, or rubber bushings, you can go ahead with silicone-based greases.

But if you’re looking for grease that can withstand a higher temperature and successfully insulate objects, stick with lithium-based lubricants. They even provide better water resistance too.

If you’re on the hunt for grease that can perform well at temperatures, but you don’t want to pick lithium greases, polyuria greases should be your next best option.

Greases are available in quite a wide range of price points. And if you want to go crazy with your lubes, pick a higher-end synthetic grease and watch it stay on for over a year!

Water Resistance

The insides of bushings need to repel moisture from getting in. Otherwise, your suspension could be in a pretty bad shape. So, make sure to choose a grease that has a good water resistance or moisture repellant rating.

Ability to Withstand Extreme Temperatures

You have to make sure that the grease that you get can withstand extreme temperatures. Things can get pretty heated up in these, and you wouldn’t even know when the grease wears off. So, pick a grease that can withstand up to 500°F.

How to Use Grease for Polyurethane Bushings?

The entire process can be pretty simple if you’re willing to learn. In most cases, you’ll have a lot more grease than you need. All the companies package their products in either tubes or tubs.

You can either go in with a finger or use a toothbrush to apply it. Greases only make the application process more manageable. Make sure you cover every single surface that will come into contact with metal. One layer would be enough in most cases.

If your bushings have metal plates along with them, you should probably grease the plates up too.

When it comes to the control-arm bushing, pick up a generous amount of lube on your finger, and cover both the inside and the outside. This will make the pivoting sequence smooth, and you don’t have to worry about squeaky noises.

It gets a lot easier to slip the bushings in when they’re all adequately greased up. Make sure you get all the surfaces covered, and you should be good to go.
