Frequently Asked Questions
Can I replace the tailgate hinges myself?
Yes, this is a very DIY-friendly job for most home mechanics. The process involves supporting the tailgate, unbolting the old hinges, and bolting on the new ones. 🎬 Watch this step-by-step Chevy truck tailgate hinge replacement guide. The most common tools needed are a socket set and possibly a pry bar. However, be aware of the potential for plug welds on the original hinges, which may require drilling.
Are tailgate hinges sold individually or in pairs?
Aftermarket hinges are typically sold in kits that include all four pieces: the two parts that mount to the truck bed and the two parts that mount to the tailgate. It is highly recommended to replace all components at the same time to ensure proper alignment and function.
What causes tailgate hinges to fail?
The primary causes of failure are rust, lack of lubrication, and simple wear and tear from years of opening, closing, and supporting weight. The plastic or metal bushings inside the hinge can wear down, leading to metal-on-metal contact, which accelerates wear and causes noise and binding.
Do I need any special tools for the job?
For most replacements, you'll just need a basic socket set (often 13mm or a T40 Torx bit). If your original hinges are plug-welded, you will also need a drill and drill bits to remove the weld. Applying a penetrating oil to rusted bolts a day before you start can also make the job much easier.
