How to Install Hood Support Pistons 02-09 Toyota 4Runner

Difficulty: Beginner · About 20 min · Toyota 4runner

Replace the hood support pistons on a Toyota 4Runner while securely supporting the hood and confirming each new support holds its load.

Steps

1. Secure the hood and remove a support

   Open the hood and support it with a prop rod rated for the task. Remove the upper and lower support fasteners, then detach the old piston.

2. Install the new support

   Install the mounting studs if required, orient the thicker piston end upward, and press its sockets onto the studs until they lock. Keep the prop rod in place.

3. Replace the other side and test

   Repeat on the opposite side, then check that both retaining clips are engaged. Remove the prop rod only after confirming the hood stays raised and lowers smoothly.

Check your vehicle’s repair manual for exact specifications and fit.
