The systems that tend to fail first on the 1998 Lexus GS, 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.
Lower ball joints and control arm bushings are common wear items due to age and mileage, leading to clunks, squeaks, and loose steering. Power steering pumps and lines can also develop leaks.
The VVT-i solenoid screens can become clogged, especially if oil changes were neglected, leading to a check engine light and rough idle. Replacement solenoids and OCV filters are often needed.

1998 Lexus GS Mileage Danger Zones
The mileage windows when the 1998 Lexus GS most commonly needs attention. Plan ahead, budget accordingly, and inspect before you cross each threshold.

At this mileage, the GS is barely broken in. Focus on ensuring routine maintenance like oil changes and tire rotations were performed on schedule.
Maintenance Zone
This is a critical interval for factory-recommended maintenance, including fluid flushes and inspection of wear items. Addressing these now prevents future issues.
Elevated Risk Zone
Many original wear components like suspension bushings and ball joints start to show their age. VVT-i system issues might begin if oil changes were stretched.
