Factors making it moderately difficult:
* Weight: Suburbans are heavy vehicles. Jacking it up safely and securely is crucial, and you might need jack stands rated for a heavy load. Working under a heavy vehicle is inherently risky.
* Accessibility: Reaching and maneuvering the shocks, especially the rear ones, can be challenging due to the vehicle's size and components surrounding the suspension.
* Bolts: Rust and corrosion, common in older vehicles, can make removing bolts difficult. You may need penetrating oil, a breaker bar, and potentially even a torch to heat stubborn bolts.
* Compression: Shocks are under pressure. Improper handling can cause injury. Following the correct procedure for releasing this pressure is essential.
* Specialized Tools: While not always strictly necessary, having the right tools (torque wrench, spring compressor, etc.) will make the job significantly easier and safer.
What makes it *not* excessively hard:
* Relatively straightforward procedure: The basic steps are fairly well-documented in repair manuals and online tutorials.
* Common repair: Plenty of resources (videos, guides) are available to help walk you through the process.
In short: If you're mechanically inclined, have the necessary tools, and are comfortable working on your vehicle, it's a doable project. However, if you're uncomfortable with any of the above points, taking it to a mechanic is a safer and potentially less frustrating option. The cost of labor might be offset by the potential for damage or injury if you attempt it without the proper skills and tools.
