Toyota 4Runner: Precaution
PRECAUTION
1. KINETIC DYNAMIC SUSPENSION SYSTEM
CAUTION:
- Be sure to check the pipe connections and whether or not any hydraulic circuit parts are damaged before performing work, as the hydraulic circuits become highly pressurized during air bleeding.
- The pipes become highly pressurized when bleeding air. If a fluid leak is discovered, immediately release the pressure and repair the fluid leak as there is danger involved.
(a) Before removing, installing and disassembling hydraulic circuit parts, clean each part to prevent mud and dirt from entering the hydraulic circuit.
(b) Always drain fluid from the bleeder plug of the stabilizer control with accumulator housing assembly to reduce pressure before removing parts, as the fluid is sealed under high pressure in the hydraulic circuit.
(c) Protect the removed/disassembled parts with plastic bags to prevent foreign matter from adhering to or entering them, and store them in a safe place.
(d) Be careful when removing, installing and disassembling the hydraulic circuit related parts, such as bleeder plugs and tube flare nuts, as fluid may leak when the parts are damaged.
