GM Chevrolet GMC Assist Step Installation and Removal. Colorado Silverado Sierra Canyon Tahoe Etc.

Introduction

This tutorial provides a step-by-step guide for installing GM Assist Steps on a Chevy Colorado, Silverado, Sierra, Canyon, Tahoe, and similar models. The process also includes the removal of old steps, making it useful for those upgrading or replacing worn-out steps.

Step 1: Gather Necessary Tools

Before you begin, ensure you have the following tools ready:

• 13 mm socket (deep well recommended)
• 3/8 inch ratchet
• 6 inch extension
• Torque wrench

Step 2: Remove Old Assist Steps

To uninstall the previous steps, follow these sub-steps:

1. Locate the bolts securing the old steps.
2. Use the 13 mm socket and ratchet to loosen (not fully remove) the top bolts.
3. Remove the bottom bolts completely.
4. Support the step with one hand while removing the last top bolt to prevent it from dropping.
5. Carefully pull the old step off the brackets and set it aside.

Step 3: Prepare for New Steps

1. Inspect the mounting brackets on the truck and clean any rust or debris.
2. If necessary, use a screwdriver to remove any old plugs or obstructions where the new brackets will go.

Step 4: Install New Assist Steps

1. Take the new GM Assist Steps and align them with the mounting brackets on the truck.
2. Start by inserting the upper bolts into the brackets to hold the step up.
3. Once the upper bolts are hand-tightened, proceed to install the lower bolts.
4. Use the extension for better access to the lower bolts, getting a few threads started before tightening.

Step 5: Torque the Bolts

1. For proper installation, torque the lower bolts first:
   • Recommended torque specification is 18 lb-ft.
   • Torque the front lower bolt, followed by the rear, and then the middle ones.
2. Next, torque the upper bolts using a 5/8 inch deep well socket for easier access.
   • Follow the same order: front, rear, and middle.

Conclusion

You have successfully installed the GM Assist Steps on your truck. Ensure all bolts are securely torqued to the specified 18 lb-ft for safety and stability. If you’re considering other upgrades or modifications, check the vehicle manual or online resources for additional guidance. Enjoy your new assist steps and the improved functionality they provide!
