What Do You Grease on a Semi-Truck?

Semi-trucks are a crucial part of the transportation industry, and they require regular maintenance in order to keep them running in top condition. One of the most important aspects of truck maintenance is knowing what to grease and when.

Greasing a semi-truck is essential for proper lubrication, which helps to reduce friction and wear on moving parts, as well as helping to prevent rust.

The most common points that require greasing on a semi-truck are the wheel bearings and fifth wheel. The wheel bearings should be greased every 10,000 miles or six months, whichever comes first.

The fifth wheel should be greased every 5,000 miles or three months. It’s important to use a high quality grease when greasing these points as it will last longer than cheaper alternatives.

In addition to the wheel bearings and fifth wheel, other components on a semi-truck that require regular greasing include the kingpins, U-joints, suspension bushings, steering system components, and drive shafts. These should be checked for proper lubrication every 10,000 miles or six months. U-joints should also be inspected for wear and re-lubricated if necessary.

Other Parts You May Need To Grease On A Semi Truck:

Some other parts that may need greasing on a semi-truck include the landing gear legs, trailer suspension bushings and shackles, air brake linkages, idler arms and tie rods. These should be inspected and lubricated as needed every 10,000 miles or six months.

Types Of Grease:

When it comes to choosing which type of grease is best for your semi-truck’s components there are many different options available. Most experts recommend using an EP (extreme pressure) or multi-purpose grease for most applications due to its ability to withstand high temperatures and resist water washout.

Conclusion:

In conclusion, it is important to know what parts of your semi truck need to be regularly greased in order to keep it running smoothly. Wheel bearings and fifth wheels should be greased every 10 000 miles or 6 months while other components such as kingpins U joints suspension bushings steering system components drive shafts landing gear legs trailer suspension bushings shackles air brake linkages idler arms tie rods etc should be checked for proper lubrication every 10 000 miles or 6 months. When choosing a type of grease experts recommend using an EP or multi purpose grease due to its ability to withstand high temperatures and resist water washout.
