Best Model Years
For the second generation (1995-2001), later model years (2000-2001) generally saw some improvements, but the key is the engine choice. A 1998 5.0L V8 is preferable to a 4.0L SOHC.
Years to Avoid
Any 4.0L SOHC V6 model with unknown maintenance history or audible timing chain noise should be avoided.
Biggest Strengths
- Rugged body-on-frame construction
- Optional 5.0L V8 engine durability
- Abundant and affordable parts availability
Top Risk Areas
The systems that tend to fail first on the 1998 Ford Explorer, 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.
The overhead cam (SOHC) V6 engine is notorious for timing chain guides/cassettes wearing out, causing severe rattling noises, oil starvation, and eventually catastrophic engine failure if neglected. This is a complex, engine-out repair.
The 5R55E automatic transmission is prone to hard shifts, delayed engagements, solenoid failures, and valve body issues, often leading to complete transmission failure. Shift quality degradation is a common precursor.
Significant rust issues affect the frame, especially in the rear sections, rocker panels, wheel wells, and tailgate. This can compromise structural integrity and make repairs difficult or impossible, particularly in salt-belt regions.
1998 Ford Explorer Mileage Danger Zones
The mileage windows when the 1998 Ford Explorer most commonly needs attention. Plan ahead, budget accordingly, and inspect before you cross each threshold.
Low Risk Zone
At this mileage, the Explorer should still be relatively trouble-free, assuming basic maintenance has been performed. Early electrical gremlins might appear, but major issues are rare.
Maintenance Zone
This mileage often marks the start of wear-and-tear items needing attention. Front suspension components (ball joints, tie rods) are likely due for replacement, and the 4.0L SOHC timing chain noise may begin to manifest.
Elevated Risk Zone
This is where the Explorer's notorious issues often become prominent. Transmission issues are increasingly likely, and rust can become a significant concern. The blend door actuator and fuel pump are also common failures.
High Risk Zone
Beyond this point, major system overhauls become increasingly probable. Catastrophic 4.0L SOHC engine failure, full transmission replacement, or severe rust compromising structural integrity are real possibilities. Only well-maintained e…
1998 Ford Explorer Ownership Cost Outlook
What it typically costs to keep the 1998 Ford Explorer on the road. Full 5-year cost-of-ownership projection and major-failure-risk forecast are in the report.
Annual Maintenance
$500-800
Moderate Repairs
$600-1,800 occasionally
How Long Does the 1998 Ford Explorer Last?
For a 1998 Explorer, assume that any vehicle over 100,000 miles will require significant investment soon, unless there's documented evidence of a recent timing chain service (on SOHC models) or transmission rebuild. Lower mileage is always better, but prioritize documented maintenance over mileage alone.
