How Do You Check a Semi Truck Suspension?

Maintaining the suspension system in a semi-truck is critical to ensure the safety of both the driver and passengers as well as help reduce wear and tear of the truck. Checking a semi-truck suspension is not a difficult task, but it is important to do it regularly to make sure that all components are operating correctly.

Inspection of Parts

The first step in checking the semi-truck suspension is to visually inspect all parts for any signs of damage or wear. This includes inspecting the shocks, struts, springs, bushings, and other components for any signs of corrosion or cracks.

It’s also important to check that all fasteners are tight and secure. If any part appears damaged or worn, it should be replaced immediately.

Checking Tire Alignment

The next step in checking the semi-truck suspension is to check the alignment of the tires. This can be done by measuring the distance between each tire with a straight edge or tape measure.

The tires should be aligned evenly across all four corners with no more than 1/8 inch difference between them. If there is more than 1/8 inch difference between any two tires, then they should be adjusted accordingly.

Checking Shock Absorbers

The shock absorbers on a semi-truck provide an extra layer of cushioning against bumps and uneven terrain that can cause wear and tear on the truck’s suspension system over time. To check these shock absorbers for proper functioning, hold down one end and release it quickly. The shock absorber should move smoothly without any jerks or sticking points indicating that it needs to be replaced soon.

Testing Steering Linkage

The steering linkage on a semi-truck provides power steering assistance for turning and maneuvering on highways and city streets alike. To check this linkage for proper functioning, jostle each joint by hand while listening for any clunking sounds indicating loose hardware or worn out parts that need replacing soon.

Conclusion

: Checking a semi-truck suspension requires inspecting components such as shocks, struts, springs, bushings and other components; checking tire alignment; checking shock absorbers; testing steering linkage; and replacing any worn out parts immediately. Regular maintenance of the suspension system can help keep drivers safe on long hauls while also reducing overall wear and tear of their truck over time.
