2008 Toyota 4Runner Mileage Danger Zones
The mileage windows when the 2008 Toyota 4Runner most commonly needs attention. Plan ahead, budget accordingly, and inspect before you cross each threshold.

This mileage often triggers more extensive maintenance, including spark plug replacement (V6), differential and transfer case fluid changes. It's also a good point to start inspecting for early signs of frame rust.
Elevated Risk Zone
At this point, suspension components like sway bar links may need attention. Front brake calipers should be inspected for sticking. On Sport Editions, the X-REAS system might begin showing signs of leaks.
High Risk Zone
This is where the more significant, though still relatively rare, issues can surface. The V8 exhaust manifold bolts are a real possibility, as are further electrical accessory failures like HVAC actuators. Frame rust could become a sever…
