AutoReplacing Shock Absorbers Using Isuzu Truck Parts

Replacing Shock Absorbers Using Isuzu Truck Parts

Shock absorbers are essential in ensuring vehicle safety, comfort, and handling, including trucks. Their purpose is to dampen the energy transferred from the suspension springs to the chassis, mitigating excess vehicle motion during transit. Using high-quality Isuzu truck parts should be your first choice when considering replacements.

Understanding the process can save you time and ensure optimal truck performance when your shock absorbers are due for a replacement. This guide offers a comprehensive look at replacing a shock absorber on an Isuzu truck effectively and accurately.

Early Signs of Shock Absorber Deterioration

Several indicators could signal the need to replace your shock absorbers:

  • Vehicle instability at high speeds
  • Uneven tire wear
  • Vehicle ‘nose-diving’ when you apply the brakes
  • Excessive bounce when you hit a road bump

Finding Spare Parts For Isuzu Trucks

For Isuzu truck owners, ensuring consistent maintenance and access to quality spare parts for trucks is crucial for optimal performance and longevity. While truck dealers may provide these parts, they sometimes face prolonged waiting periods and shortages. Consequently, exploring alternative distribution channels for OEM and aftermarket Isuzu truck parts is essential.

OEM parts manufacturers increase their market share by distributing their products through aftermarket channels. Several component manufacturers have access to technical specifications for OEM parts, allowing them to produce aftermarket parts for trucks with equivalent quality and adherence to high standards.

In some cases, alternative manufacturers capitalise on new technology to improve the specifications of aftermarket parts for trucks, resulting in enhanced performance and durability.

Note: Ensure you obtain the correct components by collecting part numbers (listed on the shock absorbers’ outer case) and using them in the ordering process.

Advantages of Alternative Aftermarket Channels

Opting for alternative channels for aftermarket parts for Japanese trucks provides several benefits for fleet managers of Isuzu trucks, including:

  1. Increased Accessibility: Alternative distribution channels ensure a steady supply of high-quality Isuzu truck parts, reducing the risk of shortages and waiting times.
  2. Affordability: Leveraging aftermarket channels often results in lower costs compared to purchasing directly from truck dealers, helping optimise maintenance budgets.
  3. Variety: Access to a broader range of options, both OEM and aftermarket, offers more choices for specialised components and improved performance.
  4. Product Enhancements: With alternative manufacturers striving to improve on existing truck parts, you can benefit from cutting-edge enhancements and developments.

Steps to Replace Shock Absorbers

Step 1: Safety Precautions

Before commencing, ensure safety precautions are met – work on a level surface, preferably with someone around. Apply the parking brake, block the truck’s wheels and lift the truck using a hydraulic lift or work in a truck pit.

Step 2: Removal of Old and Fitting New Shock Absorbers

Detach the old shock absorbers using a suitable wrench and socket. Note that the nut is welded to the frame on the top bolt for Isuzu trucks, so only the bolt will detach. Compare the old and new absorbers to ensure they are identical.

Insert the new Isuzu shock absorbers. Once the shock absorbers are in place, tighten the bolts. Isuzu recommends tightening the bolts to a torque of 29 foot-pounds for 1/2 inch (13mm) bolts and 49 foot-pounds for 9/16 inch (14mm) bolts.

Step 3: Verification

After installation, verify the shock absorbers’ effectiveness by performing a short test drive.


Regularly maintaining your truck is critical, and changing necessary components is part of the process. Remember to keep accurate parts replacement records to ensure you stay within recommended lifespan limits. Additionally, alternative sources for quality aftermarket parts for Japanese trucks provide quicker and more varied access, thus reducing vehicle downtime. A comprehensive search through a reputable distributor will avail you of all the options available.
