Maintenance has two goals: keep the jeepney usable during routes and prepare it for the community-documented roadworthiness check. A cosmetic attachment and a damaged brake system do not belong in the same priority bucket.

Core operating groups
The community components page names:
- engine and cooling
- manual transmission
- suspension
- brakes and steering
- battery and electrical systems
- lights and horn
- exhaust
Check condition indicators before spending on appearance. The source does not publish verified performance multipliers, so this guide does not claim that one engine or suspension setting is universally best.
Attachments and tuning
The community page also describes bumpers, horns, antennas, lights, rims, grills, and suspension tuning. Treat these as separate decisions:
- condition affects whether a component needs attention
- tuning changes setup
- attachments change function or appearance
Do not infer a speed or income bonus unless the current interface shows it.
Inspection connection
The community LTO page lists engine, brakes, tires, headlights, blinkers, and taillights in its roadworthiness conditions. Use the inspection checklist before visiting the officer.
For the overall catalog, return to routes, jeepneys, and parts. New players should start with the first-route guide.
Frequently asked questions
What is the best part upgrade?
This page does not rank upgrades because the checked public sources do not provide enough versioned performance data.
Which lights matter for roadworthiness?
The community LTO page names headlights, blinkers, and taillights as the complete light set.
