Setup and care for rear seats
A fold and tumble rear seat is designed to fold forward to open cargo space, then return to its seating position. The hinge and latch points take the most repeated stress, so they show wear first. Keep the latches clean and confirm they lock fully each time the seat is raised, since a partly locked seat can shift under load.
Vinyl cushions and springs hold up well with routine care, but seat frames on older Jeep bodies rely on the floor and body mounts for stability. Check those points before major trips and after off-road use. Replace worn fasteners with matching sizes and grades, and keep the seat dry to reduce corrosion.
- Check latches before each drive
- Inspect hinges for play or grit
- Keep the seat dry to limit rust
- Replace worn fasteners with matching parts
