Q: What does a spring bolt do?

It is the pivot between the leaf spring and the chassis (or shackle), allowing the spring to flex while keeping the axle correctly located.

Q: What symptoms indicate a worn spring bolt?

Clunking over bumps, the axle feeling loose, visible elongation in the spring eye, or rusted seized bolts that need replacement during maintenance.

Q: Are there other names?

Leaf spring bolt
Spring eye bolt
Shackle bolt
Spring pivot bolt
Suspension mounting bolt

Names vary by manufacturer.

Q: Do I need special tools to install?

Standard hand tools, plus a press or rubber mallet for stubborn bolts. Lift the vehicle safely and support the axle before removing the existing bolt.

Q: Should I replace both sides at once?

Yes — the opposite spring has accumulated similar wear and corrosion, and doing the job in pairs ensures symmetric suspension geometry.
