Heavy-Duty Suspension: What You Need to Know About Keeping It Working Great

Written by the Burntout Team

When heavy-duty trucks were first introduced, they were mainly used in heavy construction work. Today, heavy-duty diesel pickups are more common than ever before. While heavy-duty suspension systems were standard on heavy-duty trucks back when they were first invented, today they must be properly maintained to ensure the safety of everyone who uses them. Luckily, heavy-duty suspension systems are not extremely complicated and can be kept in great working order with regular inspections and proper use. At Burntout Diesel Performance in Pearland, Texas, we make it our mission to provide our valued customers with the highest quality suspension services. We specialize in suspension systems and have service and parts capabilities for different sizes and types of suspensions. Our experts can help you find that annoying squeak and make sure that your vehicle is safe on the road. Below, we share some information about what you need to know about keeping your heavy-duty truck suspension working great for as long as possible.

Inspect your suspension components regularly

The heavy-duty suspensions on heavy diesel pickups must be inspected regularly to ensure that they are working correctly. Components such as shock absorbers should be checked for leaks, rust, rot, and damage every six months or so. The boots that cover the ball joints of heavy-duty suspension systems should also be inspected to ensure that they are still covering the joint properly and have no holes or tears in them. If shocks fail before their designated lifespan is up, it could cause unsafe driving conditions for anyone who uses your heavy-duty truck.

Let your suspension sit for a while before driving

New heavy-duty suspensions should never be placed under extreme stress in their first 500 miles. This means that heavy-duty truck owners should let them sit for at least 500 miles after they are installed before driving the vehicle with them. After this waiting period is up, the shocks and other components of heavy-duty truck suspensions can handle normal use just fine without any additional issues or damage. Heavy-duty springs take a long time to settle after being compressed through assembly and installation, so drivers should avoid going over potholes or twisting roads within 500 miles of new spring installation as well.  

Keep heavy-duty suspensions well lubricated

As with most heavy equipment, heavy-duty suspensions should be well lubricated to ensure that they continue to work correctly. This means ensuring that the joints are greased at least once every six months if you plan on keeping your suspension for an extended period of time. Greasing suspension components helps them last longer and reduces the amount of squeaking or rattling noise made when in use. If you own a heavy-duty diesel pickup, it is important to keep its suspension working properly so that everyone who uses the vehicle is safe. 

Have heavy-duty suspensions inspected regularly by a professional

If you have a heavy-duty truck, you should have the suspension inspected every year or so. This is especially important if your heavy-duty suspension has more than 100,000 miles on it. If heavy-duty truck owners cannot afford to bring their vehicle into a shop for inspection each year, they can ask a mechanic or someone else who works with heavy machinery to inspect the suspension system of their heavy diesel pickup at home. Doing this yourself will ensure that all components of your suspension are working correctly and won't put anyone in danger of being injured from an accident due to faulty equipment. 

Keep up with your preventative maintenance

Running heavy-duty suspensions heavy loads will put wear on the components. Using heavy equipment to perform heavy jobs can have an impact on heavy-duty suspension system components, leading to reduced overall lifespan. If you use heavy machinery for work purposes, it is important to replace suspensions before they are no longer safe or reliable. Preventative maintenance is one of the best ways to keep heavy-duty truck suspensions working great at all times. Preventative heavy-duty suspension maintenance can help ensure that heavy diesel pickups and other heavy machinery will continue to work great at all times. For truck owners who plan on keeping their heavy equipment for a long time, it is important to check the status of heavy-duty suspensions at least once every six months if not more often. Inspection by a professional mechanic is another way suspensions can be kept working correctly for this extended period of time. Some areas of heavy-duty truck suspension that can benefit from professional preventative maintenance include upper control arms, lower control arms, stabilizer link, sway bar bushings, struts and shocks, strut and shock mounts, strut bearing, bump stops, springs, and spring pads.

In conclusion

If heavy-duty truck suspensions are not kept up with, they can lead to issues within heavy equipment that can cause accidents or injuries. Truck owners who plan on keeping heavy machinery for a long time should follow the steps outlined in this article. This includes inspecting heavy-duty suspensions yearly, greasing them regularly, performing preventative maintenance at least once every six months, and replacing any parts found to be faulty or damaged during inspection procedures. Heavy-duty suspensions should never be placed under extreme stress in their first 500 miles, so heavy wear is best avoided until after this time period. This can help heavy-duty suspensions work correctly for many years to come.
