Top Risk Areas
The systems that tend to fail first on the 1988 Toyota 4Runner, with the typical mileage window when each becomes a concern. Detailed repair-cost ranges and exact what-to-check inspection notes are in the full report.
Due to age and lack of modern rustproofing, frames (especially near suspension mounts), rear fenders, tailgate, and bed floors are highly susceptible to severe rust and rot, which can compromise structural integrity.
The 3VZ-E V6 engine, while torquey, is prone to head gasket failures, often due to design flaws that cause localized overheating. This is a well-documented issue that can lead to significant repair costs.
Aging wiring harnesses, power window motors, dash gauges, and various switches can become intermittent or fail entirely. While rarely critical, these issues are common and can be frustrating to diagnose.
