The starter on a 2006 Jeep Laredo (assuming a standard gasoline engine, not a diesel) is located on the
bottom of the engine, typically
on the passenger side (right side when sitting in the driver's seat). You'll need to get underneath the vehicle to see it. It's usually fairly close to the bell housing (where the transmission connects to the engine).
However, the exact location might vary slightly depending on the specific engine (e.g., 3.7L or 4.0L). It's always best to consult a repair manual specific to your Jeep's year, make, model, and engine for precise location and removal instructions. A picture of the engine bay in a repair manual can be extremely helpful.
